Ruth and I recently flew out to Minneapolis, Minnesota, USA, to attend the American Society of Plant Biologists’ (ASPB) annual conference, Plant Biology 2015.

Ruth did a sterling job of live-tweeting the scientific sessions she attended. She also spent some time stationed at the ASPB booth to talk to people about the Global Plant Council (GPC), as well as a big project we’re helping to bring to life: Plantae.org. I’ll talk more about what I did at the conference later… But first, what is Plantae.org?

The Evolution of Plantae.org

Some time ago, here at the GPC, we thought it would be a great idea if there was one, online location where plant scientists and teachers could go to look for and share new ideas, tools and resources for research and education. We tentatively called it the ‘Plant Knowledge Hub’, and set about looking for people or organizations that might be able to help us make it a reality.

In doing so, we discovered that the ASPB was interested in creating a kind of community networking and collaboration platform, for which they had the working title ‘Plant Science Exchange’. Joining forces, we decided to combine the two ideas into one big portal, now called ‘Plantae’. Extending beyond the ASPB membership, Plantae will be for plant scientists and educators all over the world. We hope it will become the leading plant science resource hub and community gathering place.

At this point, I should also mention the Society for Experimental Biology (SEB), without whose help the GPC would not have been able to move forward with this project. The SEB generously provided enough funding for my post! I joined the GPC in February as the Outreach & Communications Manager, so as well as looking after the GPC’s internal and external communications and helping to spread the word about the work of the GPC, one of my main duties is to identify and curate tools, resources and plant science information to upload to Plantae.

Building Plantae.org

I’ve made a few simple websites in the past, but nothing as complicated as an entire ‘digital ecosystem’ so taking the ‘Plant Science Knowledge Exchange Hub’ from an idea to the reality of Plantae.org was going to be a mammoth task. Fortunately we have had a lot of help!

Susan Cato, the ASPB’s Director of Member Services and Digital Marketing, and her team, have been doing a stellar job of pulling different stakeholder groups together to build and develop the Plantae platform. As well as a group of web architects to build the portal’s infrastructure, an agency called LookThink has been involved, with the unenviable task of optimizing the user experience. It’s no mean feat to take our ideas about what the platform should do, and the practicalities of how it can be built, to ensure that the final online product actually does what users want and need it to do in an intuitive, user-friendly way!

Ultimately, Plantae.org will have features such as Facebook or LinkedIn-style user profiles and groups, with the ability to ‘connect’, interact and send private messages. It will have public and private discussion boards where scientists can collaborate, talk about issues in science, or ask questions to the community and have them answered. It will eventually contain hundreds and thousands of pages of content including research papers, teaching resources, videos, posters and much more, some of which will be curated by groups like the GPC, and others uploaded directly by members. Underlying all of this, the portal needs a robust, intuitive search engine to allow users to find exactly the contact they are looking for.

User Testing the Beta Version

PlantBiology2015logoSo during the ASPB conference, I was to be found in a meeting room with Clare Torrans from LookThink, helping her to conduct some user experience analysis on an early beta version of the Plantae site. We recruited a range of potential Plantae users – from students through to senior professors – and asked them to tell us what they thought of the idea of Plantae, whether they would use it and find it useful, whether the icons, buttons and links on the screen did what they expected, and what else they would like Plantae to do.

I’d never consciously considered the ‘user experience’ of a website before, but having spent time with Clare, I now realize it’s a vital part of the build process – and now I’m analyzing every website I visit!

The feedback we received was varied: there were some clear patterns related to age, academic level, or previous experience with social media, some people pointed out elements of the site I hadn’t even noticed, or misinterpreted buttons I’d thought were obvious, but – positive or negative – all of the feedback we received was useful and will be fed back into the site development process.

When can I start using Plantae?

The site isn’t quite ready yet, but taking into account all of the data we obtained from the user testing sessions at Plant Biology 15, we will hopefully be ready for launch in the Autumn. Watch this space for more news!

James Wong: Plant Geeks Will Save The World!

By | Blog, Interviews

James Wong trained as a botanist at Kew Gardens in London, UK, before embarking on a wide and varied career encompassing broadcasting, writing and garden design. He demonstrates his passion for plants in every strand of his work, and is making a significant contribution towards raising the profile of horticulture and the plant sciences within the UK. He took some time out of his busy schedule to speak to Amelia at the Global Plant Council.

james wongJames qualified with a Masters in Ethnobotany; the study of how people use plants, in 2006. This branch of the plant sciences is very relevant to tackling pressing issues such as food security and conservation.

Plants have provided humanity with essentially every aspect of our sustenance and material culture for millennia. Being a fusion of anthropology and botany, ethnobotany is vital to understanding everything we are and everything we do.

 Humanity relies on an incredibly narrow range of plants to meet its needs, with just 3 crops providing up to 50% of our sustenance. This means civilization has pinned its future on just 0.00006% of the world’s edible plants!

With threats like climate change and a growing global population, it is simply not feasible to continue to marginalise 99.99994% of our crops. Learning about how to grow, prepare and eat those other plants is where the work of ethnobotanists is vital.

 This is just one example of how ethnobotany is essential in helping combat some of the biggest threats our species are facing in the next century. Plant geeks will indeed save the world.

To meet the needs of a growing population, many resources are currently focused on grow for flavourincreasing productivity of our large scale farming systems. However, in his most recent book, Grow for Flavour, James explores how we can increase the nutritional quality of home-grown produce. Could small-scale food production such as personal allotments or gardens have any role to play in our future food production systems?

In short, no. My tiny urban garden is just 6x6m, and there is no way that it is ever going to make a significant contribution to my calorie intake.

However (and this is a big however), even in this tiny space I can get access to a range of fruit and vegetables that could make an important contribution towards certain micronutrients in my diet. Many of these, including key phytonutrients, are not found in the limited range of crops grown commercially, at least in large quantities.

For example tomatidine, a chemical found in green tomatoes, may help improve muscle tone and reduce atrophy according to some studies. It is not really found in any supermarket produce, yet I can easily grow 10 kgs of tasty, tomatidine-rich fruit like ‘Green Zebra’ each summer. Popped in the freezer they could provide me with an important source of this phytonutrient year round that would otherwise be almost totally absent in my diet.

Home gardens can make significant financial sense too, removing cost as a barrier to nutrient availability.

The garden design studio, Amphibian Designs, was co-founded by James in 2008. “I have always been fascinated by plants and I feel that designing with them helps me express that.” This fascination has led the studio to win four Royal Horticultural Society medals for its designs, including two gold medals at the Chelsea Flower Show. Gardening is perhaps something we might associate more with art and creativity than science. However, James finds that: “creating spaces with plants and arranging them to express an idea allows me to better understand their botany.” Furthermore, having a scientific rather than arts background can be advantageous in design.

 I have no formal design training and find this actually allows me more creative freedom! I rarely know the design rules and conventions, so I don’t feel I need to slavishly devote my works to them. There is an awful lot of assumed knowledge and entrenched ideas in horticulture, much of which has no factual basis, and being an outsider means you get to circumvent all that.

Engaging the public with the plant sciences is becoming increasingly important yet the perception that plants are boring can be difficult to overcome. Could gardens and horticulture provide a way to approach this problem?

Absolutely. Humans instinctively find plants beautiful. Sadly, I do think UK horticulture has done a rather good job of suppressing this instinct in many people by holding up a singular, historical ideal as the dominant mode of what a ‘proper’ garden should be. Between the rustic woven willow and stately home symbolism, it can be very easy for many people (like me) to not associate themselves with gardening. Would food, fashion, music, art or film limit themselves to such as singular ideal? Of course not, and that explains their far more broad-based appeal.

 One of the most popular stands I saw at Chelsea Flower Show this year was for the European Space Agency, and represented how plants would be grown in space to feed astronauts and fuel interplanetary discovery. The look of wonder in faces of the kids (of all ages) as they wandered through spoke volumes. What an amazing way to engage kids with science.

So, we can’t leave without asking one final question: any tips for the budding gardeners amongst our readers?

Plants always grow and look best when planted to echo how they would naturally grow in the wild. Doing so means you will have less work, healthier plants and a perfectly matching aesthetic almost every time. Google image your favourite plants in their wild habitat and try your best to match them. The rest will take care of itself!

“So what does the Global Plant Council actually do?” – SEB Prague 2015

By | ASPB, Blog, GPC Community, Scientific Meetings, SEB

Dobrý den!

View across the Vltava river of Prague's Old Town and the Charles Bridge.


View across the Vltava river of Prague’s Old Town and the Charles Bridge.

Last week I attended the Society for Experimental Biology (SEB)’s Annual Main Meeting in the wonderful city of Prague in the Czech Republic.

Armed with a banner, a new batch of hot-off-the-press leaflets, some of our infamous GPC recycled paper pens, and a map of the world, the purpose of my trip was to staff an exhibitor’s booth at the conference to help raise awareness of the GPC and the projects and initiatives we are involved with.

2015-07-03 09.50.14To encourage delegates to speak to the exhibitors, there was a chance to win prizes in exchange for a ‘passport’ filled with stickers or stamps collected from each of the booths. This gave me a fantastic opportunity to meet people from all over the world and tell them about the Global Plant Council – even the SEB’s Animal and Cell biologists!

Many visitors to the booth were from Europe, but I also met people from as far away as Argentina, Australia, China and Vietnam. Thanks to everyone who visited the booth and gave me their email addresses to sign up for our monthly e-Bulletin newsletter!

“So what does the Global Plant Council actually do?”

This was the question I was most frequently asked at the conference. The answer is: many things! But to simplify matters, our overall remit falls into two main areas.

1) Enabling better plant science

2015-07-03 09.50.39

Visitors to our booth at SEB 2015 were asked to put their plant science on the map!

Plant science has a critical role to play in meeting global challenges such as food security, hunger and malnutrition. The GPC currently has 29 member organizations, including the SEB, representing over 55,000 plant, crop, agricultural and environmental scientists around the world. By bringing these professional organizations together under a united global banner, we have a stronger voice to help influence and shape policy and decision-making at the global level.  Our Executive Board and member organization representatives meet regularly and feed into international discussions and consultations.

The GPC also aims to facilitate more effective and efficient plant-based scientific research. Practically speaking, this means we organize, promote, provide support for, and assist with internationally collaborative projects and events. A good example is the Stress Resilience Symposium and Discussion Forum we are hosting, together with the SEB, in Brazil in October.

This meeting – which will be a satellite meeting of the International Plant Molecular Biology 2015 conference – will bring together scientists from across the world who are studying the mechanisms by which plants interact with and respond to their environments, particularly in the face of climate change. It will provide an excellent opportunity for researchers of all levels and from different regions to network and learn from each other, fostering new relationships and collaborations across borders. Registration and abstract submission is now open, so why not come along!

Importantly, as well as learning from researchers all over the world about the fantastic research they are doing, we also want to identify important research that is not being done, or which could be done better. Then, we can come together to discuss strategies to fund and fill these gaps.

You can find out more about our other current initiatives by going to our website.

2) Enabling better plant scientists

2015-07-03 12.42.41As well as physically bringing people together at meetings and events, the Global Plant Council aims to better connect plant scientists from around the world, promote plant research and funding opportunities, share knowledge and best practice, and identify reports, research tools, and educational resources.

Plant scientists have created an amazing diversity of assets for research and education, so by facilitating access to and encouraging use of these resources, we hope that a desperately needed new generation of plant researchers will be inspired to continue working towards alleviating some of the world’s most pressing problems. For example, we’re translating plant science teaching materials into languages other than English, and are helping the American Society of Plant Biologists to curate content for Plantae.org, an online resource hub and gathering place for the plant science community that will be launched later this year – stay tuned!

My #SEBSelfie! Other updates from the meeting can be found by following the hashtag #SEBAMM on Twitter.

My #SEBSelfie! Other updates from the meeting can be found by following the hashtag #SEBAMM on Twitter.

In addition, the GPC website is full of useful information including research and funding news, an events calendar, reports and white papers, fellowships and awards. We operate a Twitter account (@GlobalPlantGPC) for up-to-the-minute news and views, and a Spanish version @GPC_EnEspanol. We also have a blog (obviously!) that is regularly updated with interesting and informative articles written by the GPC staff, our two New Media Fellows, and plant scientists from across our member network. A Facebook page will be coming soon!

If you would like any more information about the projects and initiatives mentioned here, or more details about the GPC’s work, please do contact me (Lisa Martin, Outreach & Communications Manager): lisa@globalplantcouncil.org.

An Interview with Mary Williams: Plant Teaching & Social Media

By | ASPB, Blog, GPC Community, Interviews

Mary Williams headshotThis week we spoke to Mary Williams about plant science education, her role as features editor of The Plant Cell, and effective use of social media for scientists.

 

 

 

What inspired you to focus your career on education in the plant sciences? 

As a biochemistry student whose friends were arts majors, I discovered that I really enjoyed the challenge of explaining things through plain language and analogy. After a postdoc I took a faculty position at a primarily undergraduate institution where professors were encouraged to explore different approaches to teaching.

By sharing ideas and resources through ASPB Teaching Tools in Plant Biology, workshops, and my blog, I try to help young scientists gain confidence and become better teachers.

How have people responded to the Teaching Tools in Plant Biology (TTPB) you have developed, and how are these being used?

The response has been really positive. I regularly hear from undergraduates, graduate students, postdocs, lab heads and educators who are using them for a multitude of purposes including lesson preparation, self-learning and outreach. The articles can be accessed through most university libraries or via ASPB membership. They are also available throughout the developing world through the AGORA program.

The teaching tools articles are quite technical, so we didn’t anticipate that high school teachers would want to read them. However, in response to their expressed interest I started posting interesting newsclips and videos onto the various social media sites that I manage. This summer we’re moving all of the content onto a new platform, Plantae.org, which will provide a centralized place for educators to connect in what I have described as a Global Plant Science Learning Community. I’m really excited about providing a space for people to share their ideas and promote discussions about effective plant science teaching.

Why do you think teaching the plant sciences in an inspirational way proves so difficult?

The biggest obstacle is the preconception that plants are not interesting, which too often is conveyed by teachers in primary and secondary education. Additionally, many students have no first-hand experience of growing or caring for a plant, and this first-hand experience is really key. We find that many of the most engaged young people have grown up in close contact with plants, perhaps through a family’s involvement in agriculture or horticulture.

In terms of status and salaries, our society places a much higher value on medical sciences and medical research than the plant sciences; the tangible rewards of working with and studying plants are not always evident.

How can we better capture student imaginations when it comes to plants?

Giving students the opportunity to physically engage and inquire about plants is critical, and this has to span from the earliest years through university education. Students need to use all of their senses when exploring plants, and being allowed to explore in an open-ended way lets students develop an interest and curiosity about plants.

This idea of exploration and open-ended inquiry should continue into university, even in large lecture classes. Give students a pea in a pot to take home and observe. Hand out Brussels sprouts, green onions and daisies for students to pull apart and examine. Use some class time to pose open-ended questions. Good ideas are plentiful!

Innovative tools and support for teachers can also be found on sites such as Wisconsin Fast Plants developed by Paul Williams, SAPS and PlantingScience.org.

You are features editor for The Plant Cell. What does this role involve? 

TTPB is published by The Plant Cell, and we made the decision early on to focus our effort on the teaching of upper-level plant biology. This is the point at which students transition from using textbooks to the primary literature.

To write each article, I read dozens of recent papers and review articles to identify the key questions and the foundational concepts a student needs. I then create both a written article and an image-rich version of the information. Images are powerful ways to explain difficult concepts, and also are useful to people who teach and learn in languages other than English. After I finish the articles I send them out to several experts for peer review. I update the articles regularly so that they continue to reflect our current understanding.

A new initiative this year has been to draw on the talents of the community to develop additional Teaching Tools topics. We’ve been running competitions to solicit pre-proposals for development into Teaching Tools – you can read more about that here.

When did you first get involved with social media? How can social media platforms such as blogging and Twitter be of benefit to researchers? 

My social media roots stretch back to the early 1990s when I was active in the usenet email-based Arabidopsis and Plant Education newsgroups. These networks were excellent sources of resources, ideas and support as I became an independent researcher and educator.

I started using Twitter, ScoopIt and Facebook in earnest in 2011 with the encouragement of Sarah Blackford (@BiosciCareers) and the Global Plant Council’s Ruth Bastow (@plantscience). Like many people, I quickly realized the power of Twitter and other social media tools as a way to connect and converse with the broader community of plant scientists, plant educators, and other plant enthusiasts. Social media not only lets me meet and learn from plant scientists from around the world, but also keep abreast of new publications and get a glimpse into what is being discussed at conferences.

Mary’s top tips for getting started on social media:

  1. Apply the same social rules online as you would in real life
  2. Be friendly
  3. Give credit where it’s due
  4. Avoid talking about religion and politics; be culturally sensitive
  5. Listen a lot, talk a little
  6. Don’t be discouraged if it takes a while to get noticed
  7. Be professional; swearing, gossip and slander are common in the social sphere, but when it’s being broadcast to the world and recorded for posterity, think twice

A Postcard From… The Australian Society of Plant Scientists

By | Blog, GPC Community

A new feature on the Global Plant Council blog will be ‘A Postcard From…’ In these posts representatives from our member organizations will tell us about their society’s visions, aims and activities.

This pioneering ‘Postcard From’ was sent in by Gonzalo Estavillo and John Evans, both members of    the ASPS.

aspspostcard

The Australian Society of Plant Scientists (ASPS) promotes plant science in Australia, and provides professional contact within our community of teachers and researchers in plant biology. Originally fo­unded in 1958, the ASPS currently has approximately 400 members from Australia and also overseas. It provides a forum for knowledge exchange so that the membership can build on both the depth and breadth of knowledge of plant functions. ASPS offers a unifying representation of plant scientists in Australia, and is linked with the Global Plant Council and many other important international plant science organizations.

One of the main activities of the ASPS is to provide mutual support and collective mentorship to facilitate the dissemination of new research. For example, there has been a long and mutually supportive interaction between ASPS and Functional Plant Biology, which is perhaps the most prestigious journal of the Commonwealth Scientific and Industrial Research Organisation (CSIRO). ASPS is one of the foundation partner societies of ComBio, the annual international biology conference held in Australia. ASPS also sponsors other specialist workshops upon request.

The Society aims to nurture a new generation of plant scientists in many ways. It sponsors student attendance to ComBio through travel awards, and encourages active student participation by awarding poster prizes. Additionally, the RN Robertson Travelling Fellowship is available to students and early career researchers to support their research in another laboratory so as to widen their experience and raise their profile.

ASPS rewards excellence at all levels of scientific career development. Eminent plant scientists are invited to give the JG Wood or RN Robertson lectures at ComBio, in honour of the first two Presidents of the Society. Outstanding young plant scientists are recognized every year by the Peter Goldacre Award and the ASPS–FPB Best Paper Award. The commitment of ASPS to plant science education is reflected by both the ASPS Teaching Award, which recognizes innovative contributions to undergraduate teaching, and the development of online resources for plant biology teaching such as Plants in Action.

The Society’s social media platforms work with members to enhance their ability to do research and to educate others in plant sciences. The ASPS website offers the opportunity to connect with other members, get updates on the latest plant science research around the world, post jobs, student scholarship opportunities and conference announcements, and provides a growing collection of teaching resources for plants sciences. Phytogen is the Society’s newsletter blog to inform our own members and general readers with an interest in developments in Australian plant science, provide a vehicle for communicating new ideas, recent professional experiences, and forthcoming events. Finally, we use our Facebook and Twitter (@asps_ozplants) accounts to interact and engage with both scientific and general audiences. Meet us and view our photos in our ASPS Facebook page!

The Next Generation

By | ASPB, Blog, Future Directions, GPC Community, SEB

Meet Amelia and Sarah, the two newest additions to the Global Plant Council team.

As a coalition of plant and crop societies from the around the globe, the Global Plant Council (GPC) aims to bring together scientists, policy makers and other stakeholders to engage in coordinated strategies to find solutions to global problems.

The GPC currently has 29 member organizations representing thousands of scientists in diverse disciplines around the world. Online media such as this blog and the @GlobalPlantGPC Twitter account provide a fantastic resource for our member organizations to stay in touch, share ideas and develop interdisciplinary collaborations.

For Spanish speakers, we’ve also recently launched a Spanish version of our Twitter feed at @GPC_EnEspanol, kindly translated for us by Juan-Diego Santillana-Ortiz, an Ecuadorian currently studying at Heinrich-Heine University in Düsseldorf, Germany.

Amelia is in the third year of her PhD at the John Innes Centre, Norwich UK. She is researching how altering the biochemistry of epicuticular waxes affects the physiology and ultimately yield of UK wheat. She tweets @AmeliaFrizell (https://twitter.com/AmeliaFrizell)

Amelia Frizell-Armitage is in the third year of her PhD at the John Innes Centre, Norwich UK. She is researching how altering the biochemistry of epicuticular waxes affects the physiology and ultimately yield of UK wheat. She tweets @AmeliaFrizell.

To further enhance this network, the GPC has awarded two New Media Fellowships to early career plant scientists Amelia Frizell-Armitage and Sarah Jose. The role of the Fellows will be to increase visibility of the GPC through managing this blog, devising new strategies to promote GPC activities and to increase traffic flow and engagement on Twitter.

A key priority will be to increase members’ contributions to this blog to promote their organizations and associated activities. Contributing to the blog is a fantastic way to interact with other GPC members, and we are always open to suggestions for guest posts. Perhaps you want to talk about a recent meeting or activity, discuss a particularly exciting piece of emerging research, promote a newly published book, or even just give some insight into your everyday life?

Sarah Jose is a third year PhD student at the University of Bristol, UK. She is investigating the link between wax biosynthesis and stomatal development in barley and Arabidopsis, and its potential impact on the water use efficiency of plants. Find her on Twitter @JoseSci.

Can you crowdfund the sequencing of a plant genome?

By | Blog, Future Directions, Global Change
Dr Peng Jiang, University of Georgia, USA

Dr Peng Jiang, University of Georgia, USA

Peng Jiang and Hui Guo at the University of Georgia think you can! They are currently raising money via a crowdfunding approach to sequence the first cactus genome – but the question is: why would they want to? Peng explains all in this guest blog post.

A Prickly Proposal: Why Sequence the Cactus?
In these times of growing food insecurity due to climate change and population pressures, the prickly pear cactus (Opuntia ficus) has growing commercial and agricultural importance across much of the world – you will find it growing in Mexico and Brazil, Chile, large parts of India and South Africa, and in Spain and Morocco.

The goal of our proposal is to sequence the genome and transcriptome of the prickly pear cactus, a recognized food and forage crop in these challenging semiarid regions of the world.

With more than 130 genera and 1,500 species of Cactaceae, we will create a draft genomic and transcriptome database that would aid the understanding of this understudied plant family, and provide the research community with valuable resources for molecular breeding and genetic manipulation purposes. Here are some of the reasons why we think a first cactus genome would be so important:

The Prickly Pear Cactus

The Prickly Pear Cactus

1. Ecological Improvement
The beauty of the drought-tolerance cactus is that it can grow on desert-like wastelands. Nowadays, more than 35% of the earth’s surface is arid or semiarid, making it inadequate for most agricultural uses. Without efforts to curb global warming, “Thermageddon” may hit in 30–40 years time, causing desertification of the US, such that it may become like the Sahara. Opuntia helps create a vegetative cover, which improves soil regeneration and rainfall infiltration into the soil. This cactus genome research may help us to adapt our food crops to a much hotter, drier climate.

2. Food Crops, Feed and Medicine
The fruits of prickly pear cactus are edible and sold in stores under the name “tuna”. Prickly pear nectar is made with the juice and pulp of the fruits. The pads of prickly pears (“Nopalito”) are also eaten as a vegetable. Both the fruits and pads of prickly pears can help keep blood sugar levels stable because they contain rich, soluble fibers. The fruit contains vitamin C and was used as an early cure for scurvy.

Furthermore, there has been much medical interest in the prickly pear plant. Studies [1, 2, 3] have shown that the pectin contained in prickly pear pulp lowers cholesterol levels. Another study [4] found that the fibrous pectin in the fruit may lower a diabetic’s need for insulin. The plant also contains the antioxidant flavonoids quercetin, (+)-dihydroquercetin (taxifolin), quercetin 3-methyl ether (isorhamnetin) and kaempferol, which have a protective function against the DNA damage that leads to cancer.

3. Biofuels in Semiarid Regions
Planting low water use, Crassulacean acid metabolism (CAM; a water saving mode of photosynthesis) biofuel feedstocks on arid and semiarid lands could offer immediate and sustained biogas advantages. Opuntiapads have 8–12% dry matter, which is ideal for anaerobic digestion. With an arid climate, this prevents the need for extra irrigation or water to facilitate the anaerobic digestion process. Requiring only 300 mm of precipitation per year, Opuntiacan produce a large amount of dry matter feedstock and still retain enough moisture to facilitate biogas production. It’s possible to get as much as 2.5 kWh of methane from 1 kg of dry Opuntia.

4. Phylogenetic Importance
Trained botanists and amateurs alike have held cacti in high regard for centuries. The copious production of spines, lack of leaves, bizarre architecture and impressive ability to persist in the harshest environments on Earth are all traits that have entitled this lineage to be named a true wonder of the plant world.

The cacti are one of the most celebrated radiations of succulent plants. There has been much speculation about their age, but progress in dating cactus origins has been hindered by the lack of fossil data for cacti or their close relatives. Through whole genome sequencing, we help will reveal the genomic evolution of Opuntia by comparing this genome with that of other sequenced plant species.

Cacti are typical CAM plants. We will analyse the evolution of CAM genes in the cactus to help reveal the secret of drought tolerance. Furthermore, plant architecture genes and MADS-box gene family members will be analysed to reveal the specific architecture and structure of cactus.

Crowdfunding the Cactus Genome Project
Cactus has several fascinating aspects that are worth exploring, not just for its biology, but also its relevance to humanity and the global environment. We plan to generate a draft genome for Opuntia, and have launched a crowdfunding campaign to help fund this project – we have already raised $2300 USD (46% of what we need), but we only have 15 days to raise the rest. If you would like to help fund this project, please visit our Experiment page at: https://experiment.com/projects/sequencing-the-cactus-genome-to-discover-the-secret-of-drought-resistance.

If we are successful in raising enough money to initiate the Cactus Genome Project, not only will this be the first plant genome to be sequenced in the Cactaceae family, we will be releasing the results to the plant science community through GeneGarden, an ornamental plant genome database. Our citizen science approach is also allowing us to reach out directly to members of the public, creating exciting opportunities for outreach and engagement with plant science.

If you have any further questions, please contact project leader Dr Peng Jiang at pjiang@uga.edu.
