New study: Forests are still underrated as allies to curb rural poverty

By | Climate change, Forestry, Future Directions, News

In the face of the Covid-19 pandemic and the mounting threat of climate change, forests and trees are vital for the rural poor in countries around the world. However, the poor are rarely able to capture the bulk of benefits from forests. A global science assessment analyses how forests can realize their potential to reduce poverty in a fair and lasting manner.

How plants ensure regular seed spacing

By | Agriculture, CEPLAS, Future Directions, News, Plant Science, Research

An international team of researchers led by biologists has examined how seed formation is coordinated with fruit growth. In their report, they explain the genetic control mechanisms underlying the process. If you open up a pea pod, you will find that all of the peas inside are the same size and the same distance apart. The same is true of princess beans, runner beans and soybeans as well as various other peas and beans, and it also applies to non-pulses. This is surprising because both the seed size and number and the pod size differ substantially from one variety to the next.

Large-scale genomics will improve the yield, climate-resilience, and quality of bread wheat, new study shows

By | Future Directions, News, Plant Science, Research

Scientists identified significant new chromosomal regions for wheat yield and disease resistance, which will speed up global breeding efforts.

Using the full wheat genome map published in 2018, combined with data from field testing of wheat breeding lines in multiple countries, an international team of scientists has identified significant new chromosomal regions for wheat yield and disease resistance and created a freely-available collection of genetic information and markers for more than 40,000 wheat lines.

Reported in Nature Genetics, the results will speed up global efforts to breed more productive and climate-resilient varieties of bread wheat, a critical crop for world food security that is under threat from rising temperatures, rapidly-evolving fungal pathogens, and more frequent droughts, according to Philomin Juliana, wheat scientist at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new study.

“This work directly connects the wheat genome reference map with wheat lines and extensive field data from CIMMYT’s global wheat breeding network,” said Juliana. “That network in turn links to over 200 breeding programs and research centers worldwide and contributes to yield and other key traits in varieties sown on nearly half the world’s wheat lands.”

The staple food for more than 2.5 billion people, wheat provides 20% of human dietary calories and protein worldwide and is critical for the nutrition and food security of hundreds of millions of poor persons in regions such as North Africa and South Asia.

“Farmers and societies today face new challenges to feed rising and rapidly-urbanizing populations, and wheat epitomizes the issues,” said Ravi Singh, CIMMYT wheat breeder and corresponding author of the study. “Higher temperatures are holding back yields in major wheat-growing areas, extreme weather events are common, crop diseases are spreading and becoming more virulent, and soil and water are being depleted.”

Juliana said the study results help pave the way to apply genomic selection, an approach that has transformed dairy cow husbandry, for more efficient wheat breeding.

“Molecular markers are getting cheaper to use; meanwhile, it’s very costly to do field testing and selection involving many thousands of wheat plants over successive generations,” Juliana said. “Genome-wide marker-based selection can help breeders to precisely identify good lines in early breeding generations and to test plantlets in greenhouses, thereby complementing and streamlining field testing.”

The new study found that genomic selection could be particularly effective in breeding for wheat end-use quality and for resistance to stem rust disease, whose causal pathogen has been evolving and spreading in the form of highly-virulent new races.

The new study also documents the effectiveness of the global public breeding efforts by CIMMYT and partners, showing that improved wheat varieties from this work have accumulated multiple gene variants that favor higher yields, according to Hans-Joachim Braun, director of CIMMYT’s global wheat program.

“This international collaboration, which is the world’s largest publicly-funded wheat breeding program, benefits farmers worldwide and offers high-quality wheat lines that are released directly to farmers in countries, such as Afghanistan, that are unable to run a full-fledged wheat breeding program,”

Braun explained.

The study results are expected to support future gene discovery, molecular breeding, and gene editing in wheat, Braun said.

Together with more resource-efficient cropping systems, high-yielding and climate-resilient wheat varieties will constitute a key component of the sustainable intensification of food production described in Strategy 3 of the recent EAT-Lancet Commission recommendations to transform the global food system. Large-scale genomics will play a key role in developing these varieties and staying ahead of climate- and disease-related threats to food security.

Second post of our “Global Collaboration” series

Earning a graduate degree in the life sciences is all about preparing students to become productive and competitive in today’s scientific field; ensuring they are at the cutting edge of technology and knowledge. However, one aspect of graduate education that is seemingly overlooked is extending outside of the lab and learning how to become a scientist in the global community. This oversight is something that scientists at the University of Missouri and China Agricultural University are working to combat.

In August 2018, faculty, graduate students and post-docs from both universities came together in Beijing for a workshop to discuss scientific areas of expertise ranging from wetland ecology to crop modeling. This allowed attendees to practice collaborating with other scientists internationally and across disciplines.

Joint Scicomm US-China Workshop

Introducing the concept of breaking multiple “language” barriers

One of the key skills the graduate students developed during the workshop was how to communicate science in multiple languages. The students had to overcome the challenges of communicating science in English and Chinese along with explaining it to scientists outside of their disciplines and then take those experiences and turn them into videos, stories and blog posts that the public could enjoy. 

Needless to say, the students quickly learned that not only is science communication difficult, but the degree of difficulty rises exponentially when trying to communicate with an audience outside of your native language and discipline. To tackle the language barrier, students avoided jargon and slowed their speaking pace to clearly articulate their points. Many times, the students from the two universities took the breaks between sessions to really talk to each other about the presentation content to solidify what the takeaways were. It was these informal discussions that led to very productive conversations. Students also pointed out the similarities and differences between their projects, allowing for bridges to be built between what would normally be very different fields. 

Another part of this workshop helped the students to learn how to better engage with the general public. While in China, the Missouri graduate students performed journalistic tasks in order to demonstrate what they learned and experienced during the workshop. They took video footage, interviewed workshop attendees and conceptualized how to turn all of that content into stories. When the Missouri students returned home, they began the process of creating content about the China trip. They had to make sure all videos, blogs, and articles were easily understandable to a non-science audience since everything would be eventually posted online at https://rootsindrought.missouri.edu/ and on Youtube.

Through this experience, University of Missouri students were able to take what they had learned in theory and put it into practice. These skills will help them to have a unique advantage compared with their peers and help them as they move into their academic and professional careers. 

Conclusions

There is no question that the scientific field is becoming more global and the general public is becoming increasingly skeptical of science. This makes it critical that we begin developing graduate programs to incorporate experiences that allow students to engage in the world outside the lab and learn to communicate why their science is beneficial to society, both at home and abroad.
