Creating stress resilient agricultural systems: Video interviews

By | Blog, Scientific Meetings, SEB

The global population is projected to reach 9.6 billion by 2050, and to accommodate this, crop production must increase by 60% in the next 35 years. Furthermore, our global climate is rapidly changing, putting our cropping systems under more strain than ever before. Agriculture will need to adapt to accommodate more extreme weather events and changing conditions that may mean increased instance of drought, heatwaves or flooding. The Global Plant Council Stress Resilience initiative, was created to address these issues.

Back in October the Global Plant Council, in collaboration with the Society for Experimental Biology brought together experts from around the world at a Stress Resilience Forum to identify gaps in current research, and decide how best the plant science community can move forwards in terms of developing more resilient agricultural systems. We interviewed a number of researchers throughout the meeting, asking about their current work and priorities for the future.  Watch the best bits in the video below:

Now That’s What I Call Plant Science 2015

By | Blog, Research, Science communication

With another year nearly over we recently put out a call for nominations for the Most Influential Plant Science Research of 2015. Suggestions flooded in, and we also trawled through our social media feeds to see which stories inspired the most discussion and engagement. It was fantastic to read about so much amazing research from around the world. Below are our top five, selected based on impact for the plant science research community, engagement on social media, and importance for both policy and potential end product/application.

Choosing the most inspiring stories was not an easy job. If you think we’ve missed something, please let us know in the comments below, or via Twitter! In the coming weeks we’ll be posting a 2015 Plant Science Round Up, which will include other exciting research that didn’t quite make the top five, so watch this space!

  1. Sweet potato is a naturally occurring GM crop

Scientists at the International Potato Center in Lima, Peru, found that 291 varieties of sweet potato actually contain bacterial genes. This technically means that sweet potato is a naturally occurring genetically modified crop! Alongside all the general discussion about GM regulations, particularly in parts of Europe where regulations about growing GM crops have been decentralized from Brussels to individual EU Member States, this story caused much discussion on social media when it was published in March of this year.

It is thought that ancestors of the modern sweet potato were genetically modified by bacteria in the soil some 8000 years ago. Scientists hypothesize that it was this modification that made consumption and domestication of the crop possible. Unlike the potato, sweet potato is not a tuber but a mere root. The bacteria genes are thought to be responsible for root swelling, giving it the fleshy appearance we recognize today.

This story is incredibly important, firstly because sweet potato is the world’s seventh most important food crop, so knowledge of its genetics and development are essential for future food supply. Secondly, Agrobacterium is frequently used by scientists to artificially genetically modify plants. Evidence that this process occurs in nature opens up the conversation about GM, the methods used in this technology, and the safety of these products for human consumption.

  1. RNA-guided Cas9 nuclease creates targetable heritable mutations in Barley and Brassica

Our number two on the list also relates to genetic modification, this time focusing on methods. Regardless of whether or not we want to have genetically modified crops in our food supply, GM is a valuable tool used by researchers to advance knowledge of gene function at the genetic and phenotypic level. Therefore, systems of modification that make the process faster, cheaper, and more accurate provide fantastic opportunities for the plant science community to progress its understanding.

The Cas9 system is a method of genome editing that can make precise changes at specific locations in the genome relatively cheaply. This novel system uses small non-coding RNA to direct Cas9 nuclease to the DNA target site. This type of RNA is small and easy to program, providing a flexible and easily accessible system for genome editing.

Inheritance of genome modifications using Cas9 has previously been shown in the model plants, Arabidopsis and rice. However, the efficiency of this inheritance, and therefore potential application in crop plants has been questionable.

The breakthrough study published in November by researchers at The Sainsbury Laboratory and John Innes Centre both in Norwich, UK, demonstrated the mutation of two commercial crop plants, Barley and Brassica oleracea, using the Cas9 system and subsequent inheritance mutations.

This is an incredibly exciting development in the plant sciences and opens up many options in the future in terms of genome editing and plant science research.

  1. Control of Striga growth

Striga is a parasitic plant that mainly affects parts of Africa. It is a major threat to food crops such as rice and corn, leading to yield losses worth over 10 billion US dollars, and affecting over 100 million people.

Striga infects the host crop plant through its roots, depriving them of their nutrients and water. The plant hormone strigolactone, which is released by host plants, is known to induce Striga germination when host plants are nearby.

In a study published in August of this year the Striga receptors for this hormone, and the proteins responsible for striga germination were identified.

Striga plants are known to wither and die if they cannot find a host plant upon germination. Induction of early germination using synthetic hormones could therefore remove Striga populations before crops are planted. This work is vital in terms of regulating Striga populations in areas where they are hugely damaging to crop plants and people’s livelihoods.

  1. Resurrection plants genome harvesting

Resurrection plants are a unique group of flora that can survive extreme water shortages for months or even years. There are more than 130 varieties in the world, and many researchers believe that unlocking the genetic codes of drought-tolerant plants could help farmers working in increasingly hot and dry conditions.

During a drought, the plant acts like a seed, becoming so dry that it appears dead. But as soon as the rains come, the shriveled plant bursts ‘back to life’, turning green and robust in just a few hours.

In November, researchers from the Donald Danforth Plant Science Centre in Missouri, US, published the complete draft genome of Oropetium thomaeum, a resurrection grass species.

O. thomaeum is a small C4 grass species found in Africa and India. It is closely related to major food feed and bioenergy crops. Therefore this work represents a significant step in terms of understanding novel drought tolerance mechanisms that could be used in agriculture.

  1. Supercomputing overcomes major ecological challenge

Currently, one of the greatest challenges for ecologists is to quantify plant diversity and understand how this affects plant survival. For the last 500 years independent research groups around the world have collected this diversity data, which has made organization and collaboration difficult in the past.

Over the last 500 years, independent research groups have collected a wealth of diversity data. The Botanical Information and Ecology Network (BIEN) are collecting and collating these data together for the Americas using high performance computing (HPC) and data resources, via the iPlant Collaborative and the Texas Advanced Computing Center (TACC). This will allow researchers to draw on data right from the earliest plant collections up to the modern day to understand plant diversity.

There are approximately 120,000 plant species in North and South America, but mapping and determining the hotspots of species richness requires computationally intensive geographic range estimates. With supercomputing the BIEN group could generate and store geographic range estimates for plant species in the Americas.

It also gives ecologists the ability to document continental scale patterns of species diversity, which show where any species of plant might be found. These novel maps could prove a fantastic resource for ecologists working on diversity and conservation.

The Global Plant Council Guide To Social Media

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

Here at the GPC we love social media. It provides a fantastic platform upon which we can spread awareness about our organisation and the work we do. Since Lisa Martin’s appointment as Outreach and Communications Manager in February of this year, and the New Media Fellows two months later, we have expanded our online presence and are reaching more people than ever before. We still have a way to go, but here are a few things we’ve learnt over the past year that might provide you with a bit more social media know-how.

  1. Tweet, tweet, and tweet some more

To increase your following as an individual try to produce maybe one or two good tweets everyday. If you’re tweeting on behalf of an organization and have more time or people power, 5–8 tweets a day should be your target.

Global Plant Council twitter account

The Global Plant Council twitter account now has over 1500 followers. Find us @GlobalPlantGPC

Our Twitter following has grown rapidly over the past year. We had 294 followers on Twitter in September 2014 and now have over 1500! Much of this has been down to there now being four of us maintaining the account rather than Ruth Bastow (@PlantScience) on her own.

The more you tweet, and the better you tweet, the more followers you will get. Things move fast in the Twittersphere, so just a few days of inactivity can mean you drop off the radar.

For more hints about using Twitter see this great article from Mary Williams (@PlantTeaching): Conference Tweeting for Plant Scientists Part 1 and Part 2.

  1. If your followers won’t come to you, go to your followers

Decide on who you want to connect with, find out which social media platform they se most, and set yourself up!

As a global organization we want to connect with all our members and plant scientists around the world, so we need to use different means of communication to do this. In April 2015 we set up a Spanish language Twitter account with Juan Diego Santillana Ortiz (@yjdso), an Ecuadorian-born PhD student at Heinrich-Heine University in Dusseldorf, Germany, who translates our tweets into Spanish.

Of course Twitter is not universally popular, and our main following seems to come from the

Scoopit

The newest edition to the GPC social media family is our GPC Scoop.It account which you can find here

UK and US. To connect with those choosing to use different communication platforms, New Media Fellow Sarah Jose set up a GPC Scoop.It account in September 2015. Around this time we also set up a GPC Facebook page after many of our member organizations told us this was their primary means of connecting with their communities. Although relatively new, this page is slowly gaining momentum and we hope it will provide a great outlet for conversation in the future. Find out about which of our member organizations are on Facebook here.

If there’s a site you use to stay up to date with science content that we don’t have a presence on, do let us know and we will look into setting up an account!

  1. Generate your own content

Ultimately, the best way to expand your reach online is to generate your own content.

The GPC blog was started in October 2014, and in its first 14 months of life received an average of 142 views per month. However, since Lisa, myself and Sarah started working with the GPC, we have been generating one blog post every week, with the result of our monthly views shooting up to almost 700 views per month since May.

This just shows that generating interesting and regular content really does work in terms of increasing reach and online presence. All these blog posts have also contributed towards a growing following on our various social media sites over the past six months.

If you want to write for us, please send us an email or get in touch on Twitter! We are always looking for contributions from the plant science community. Perhaps you’ve recently attended a scientific meeting, are doing a really cool piece of research, organized a great outreach activity or have seen something relevant in the news. Whatever it is, we want to know.

We’re also happy to write about the GPC for your blog or website, so if you would like us to contribute an article, please get in touch!

  1. Cover as many platforms as possible

Try to have a global presence across as many platforms as you think you can maintain, although an inactive account on any social media site won’t do you any favors, so don’t take on too much!

I’ve already described our presence on Twitter, Facebook, Scoop.It and the blog, all of which help make our organization accessible, however people want to use social media.

In addition to this we of course have the GPC website, and Lisa sends out a monthly e-Bulletin providing a summary of all the information published on the website for that month. Anyone can sign up here to stay up to date with our activities, and it’s free!

In a bid to further reach out to members that perhaps don’t engage with social media (yet!), Lisa wrote this article explaining what the GPC does and sent it out to be published by our various member organizations.

  1. Plantae
New Media Fellow Sarah Jose promotes our new Plantae platform at IPMB 2015

Confession time, this isn’t really a helpful hint on how to use social media, but Plantae is so good it deserves a section all on its own!

We are hoping Plantae, set up by the GPC in collaboration with the ASPB, and with support from the SEB, will be the digital ecosystem for the plant science community. It will provide a platform for plant scientists to collaborate with one another, network, and access journals, advice and jobs. You can read more about Plantae on our blog, here.

It’s now in beta testing and you can sign up to give it a go at http://www.plantae.org. Let us know what you think!

Plant Biology Scandinavia 2015

Celia Knight and Saijaliisa Kangasjarvi at the conference dinner

The 26th Scandanavian Plant Physiology Society (SPPS) Congress took place from the 9th – 13th August at Stockholm University. Celia Knight attended the meeting and has written a report for the blog this week, so that those of you who couldn’t attend are up to speed!

A diversity of speakers and topics

Attending SPPS 2015 was a fantastic opportunity to hear about progress across a really broad spectrum of plant biology research. The program included sessions on development, epigenetics and gene regulations, high-throughput biology, photobiology, abiotic stress, education and outreach, and biotic interactions. There really was something for everyone! Additionally, the organizers had made a notable effort to include a good mix of both established and early career researchers, further adding to the diversity of talks on offer.

I was struck by the contributions from the various Society awards so will focus on these.

SPPS awards

Gunnar Öquist (Umeå University, Sweden) was given the SPPS Award in recognition of his outstanding merited contribution to the science of plant biology. His talk entitled “My view of how to foster more transformative research” provided a reminder that the dual aims of research, both to solve problems and to seek new knowledge, are very important if global challenges are to be met.

The SPPS early career award recognizes a highly talented scientist who has made a significant contribution to Scandinavian plant biology. This year two early career awards were given. The first recipient, Ari-Pekka Mähönen (University of Helsinki, Finland), received the award for his work on growth dynamics in Arabidopsis thaliana, and showed some amazing sections to follow cambium development. Nathaniel Street (Umeå University, Sweden) also received an award for his work “Applying next generation sequencing to genomic studies of Aspen species and Norway Spruce”. Both gave great talks including strong research in these areas; it was great to see upcoming researchers take the spotlight and give us a glimpse to the future of plant biology.

Torgny Näsholm (SLU, Umeå Sweden) was awarded the Physiologia Plantarum award. This award is given to a scientist that has made significant contribution to the areas of plant science covered by the journal Physiologia Plantarum. Torgny uses microdialysis, a technique currently used by neuroscientists, to investigate the availability of soil nitrogen to plants. Data generated using this technique are now bringing into question our current view of nitrogen availability measured using traditional methods.

Additional activities included a tour of the Bergius Botanic Garden

The Popularisation prize, awarded to Stefan Jansson (Umeå University, Sweden), recognizes significant contributions to science communication and public engagement. Stefan’s work in public engagement has been wide-ranging. He has been involved with The Autumn Experiment, a citizen science project engaging schools in observation, data collection and real research. Recently Stefan published a book in Sweden, called ‘GMO’, which tackles the response of societies to genetically modified organisms.

At the congress, Stefan took over as the new President of the SPPS. This could lead to further emphasis and resources being placed on communicating science as the society moves forward.

Poster prizes

Prizes for the best posters are also awarded at the meeting. Five judges, including myself, assessed the posters, and the competition was fierce. It was impossible to split the top prize, so joint 1st prizes were awarded to Veli Vural Uslu (Heidelberg University, Germany) on “Elucidating early steps of sulfate sensing mechanisms by biosensors” and to Timo Engelsdorf (Norwegian University of Science and Technology, Norway) for “Plant cell wall integrity is maintained through cooperation of different sensing mechanisms”. Joint second prizes went to Zsofia Stangl (Umeå University, Sweden) on “Nutrient requirement of growth in different thermal environments” and to Annika Karusion (University of Tartu, Estonia) for “Circadian patterns of hydraulic and xylem sap properties: in situ study on hybrid aspen.”

Additional activities

Like any meeting, SPPS wasn’t all work and no play! Lisbeth Jonsson (Stockholm University, Sweden) and her team organized an excellent program. I feel very fortunate, on this short trip, to have had the opportunity to view Stockholm’s fine City Hall where Nobel laureates have dined, as well  as the incredibly preserved Vasa ship, which sank in Stockholm bay on its maiden voyage in 1628.

I very much look forward to seeing how the society progresses in the future, and nurturing new friendships and collaborations I made at the congress.

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!

An interview with Ellen Bergfeld

By | Blog, GPC Community, Interviews

EllenBergfeldThis week, New Media Fellow Amelia Frizell-Armitage has been talking to Ellen Bergfeld, CEO of the Alliance of Crop, Soil and Environmental Science Societies (ACSESS), a coalition of the American Society of Agronomy (ASA), Crop Science Society of America (CSSA) (both of which are Global Plant Council member organisations) and the Soil Science Society of America (SSSA). She spoke to us about the societies, her role as CEO, and her visions for the future.

What is the purpose of the ACSESS?

ACSESS is a nonprofit organization founded by the ASA, CSSA and SSSA to support the activities of member societies.

ACSESS has five primary goals. 1) Firstly, we help professional societies representing agronomic, crop, soil, and environmental sciences to collaborate and 2) advance the missions, visions, and activities of these societies. 3) We promote the value and image of agronomic, crop, soil and environmental resource professions, and 4) unify communication with scientists, educators, policy-makers, and the public to enhance impact. Finally, 5) we engage science-based knowledge on the challenges facing humanity.

How do the work and aims of the ACSESS coalition cross over with those of the Global Plant Council (GPC)?

The GPC’s goal to feed an ever-growing human population sustainably is of paramount interest and importance to all three of our member societies.

Additionally, all three societies advocate nationally and internationally for plant and crop sciences. They act as catalysts to generate plant-based solutions for the sustainable intensification of agriculture, whilst preserving biodiversity, protecting the environment, reducing world hunger, and improving human health and wellbeing.

In your opinion, what will be the biggest challenges over the next 50 years in terms of food production and agriculture?

Three things: climate change, degraded and decreased natural resources, and population growth.

What do you think our top priorities should be in terms of tackling these issues?

Adapting plants to climatic changes and developing crops that can be sustainably grown in the field is a top priority, and very broad in terms of the research required.

Another large gap I see is education and science literacy. By educating and empowering communities, particularly girls and women, regarding the carrying capacity of the planet, we can open up discussions and raise awareness of the need for sustainability in all aspects of our lives.

What are the key developments in agronomy required to ensure sustainable agriculture in the future?

If we continue to deplete our soil and water resources, this will have a dire impact on our ability to feed the population. We need to recognize this, and adapt our agricultural practices accordingly.

2015 is International Year of Soils. Can you sum up in one sentence why soils are so important?

 Soils Sustain Life!

What inspired you to leave academia and move into science policy, strategy and administration?

At the time I was looking to graduate, I would have had to do multiple postdocs to be competitive for an academic position. I enjoyed the teaching and working with animals, but not the lab work or grant writing.  I pursued the Congressional Science Fellowship to open new doors and took advantages of the opportunities that followed.

Day to day, what is the most rewarding part of your job as CEO?

I enjoy connecting our sciences, and scientists, to address the global challenges that we face.

Interacting with the best and brightest minds who are collectively addressing these challenges is incredibly inspiring and fulfilling.

Ellen Bergfeld received her BSc in Animal Science from Ohio State University, going on to study reproductive physiology, first at masters then PhD level, at the University of Nebraska-Lincoln.  After graduating she was awarded the Federation of Animal Science Societies Congressional Science Fellowship. This Fellowship provides an opportunity for highly skilled scientists to spend a year working in congress as special assistants in legislative areas. Following the fellowship Ellen became Executive Director of the American Society of Animal Science. Ellen is now CEO of ACSESS.
