BERKELEY (August 5, 2020) – Newly emerged pathogens can lead to disease epidemics that create severe crop losses and threaten food security. The Foundation for Food and Agriculture Research (FFAR) awarded a $900,000 Seeding Solutions grant to the University of California, Berkeley to address devastating disease epidemics through advanced gene editing technologies. 2Blades Foundation and Innovative Genomics Institute provided matching funds, for a total $3.2 million investment.

Currently, breeding plants for disease resistance is the most effective and ecologically sustainable way to control plant epidemics. To achieve this, scientists use traditional crop breeding to introduce, or stack, multiple resistance genes – though this is a time-consuming approach. Additionally, the effectiveness of stacking resistance genes in economically vital crops like wheat are often short lived as the pathogens are constantly evolving to overcome resistance.

“A virulent wheat pathogen would not only harm farmers, but can also result in food supply shortages, threatening food security,” said FFAR Executive Director Sally Rockey. “Thus, scientists need a new approach to breeding wheat crops with greater disease resistance.”

Pathogens have special proteins that can cause plant disease. University of California, Berkeley researchers, led by Dr. Brian Staskawicz and Dr. Ksenia Krasileva, are using gene editing technology to stack resistance genes in the wheat crops that specifically recognize the pathogen’s proteins. By recognizing the pathogen’s proteins, the plant can fight the pathogen, even if the pathogen mutates.

In addition to using already cloned genes, this grant is also addressing the ability of combined computational and synthetic biology approaches to develop novel resistance genes. Outputs of the program will be advanced through The 2Blades Foundation’s wheat rusts consortium to ensure delivery of rust-resistant wheat.

“We are excited to employ gene editing in wheat, as it will allow us to reduce farm inputs and produce more sustainable wheat yields — more important than ever in the face of climate change,” said Staskawicz.

Ultimately, this project is accelerating the development of improved resistant wheat varieties and getting them to farmers. The resulting wheat varieties will have greater yields and require fewer chemical inputs. Improving the quality of wheat ensures the crop is robust enough to grow worldwide.

Overcoming Water Scarcity

Overcoming Water Scarcity

Continue

Agriculture uses 70 percent of the world’s accessible freshwater. FFAR’s 2016-2018 Overcoming Water Scarcity Challenge Area addressed water use efficiency in agriculture by developing water conservation and reuse technologies, improving crop and livestock breeds, creating improved agronomic practices, increasing the social and economic tractability of conservation practices and enhancing the efficacy of Extension services.

FFAR’s Sustainable Water Management Challenge Area builds on earlier work to increase water availability and water efficiency for agricultural use, reduces agricultural water pollution and develops water reuse technologies.

FFAR’s 2016-2018 Protein Challenge Area sought to improve the environmental, economic and social sustainability of diverse proteins.

The Advance Animal Systems challenge area supports sustainable animal production through environmentally sound productions practices and advancement in animal health and welfare. Additionally, the Next Generation Crops Challenge Area develops non-traditional crops, including plant-based proteins, and creates new economic opportunities for conventional crops to increase future crop diversity and farm profitability.

Food Waste and Loss

Food Waste and Loss

About 40 percent of food in the US, or $161 billion each year, is lost or wasted. FFAR’s 2016-2018 Food and Waste Loss Challenge Area addressed the social, economic and environmental impacts from food waste and loss through research that developed of novel uses for agricultural waste, improved storage and distribution, supported tracking and monitoring, minimized spoilage through pre- and post-harvest innovations and changed behaviors to reduce food waste

FFAR’s current Health-Agriculture Nexus Challenge Area addresses food waste and loss and supports innovative, systems-level approaches to reduce food and nutritional insecurity and improve human health in the US and globally.

Forging the Innovation Pathway to Sustainability

Continue

Supporting innovation is necessary for sustainable results. Over the last 50 years, farmers have tripled global food production thanks to agricultural innovations. Forging the Innovation Pathway to Sustainability was a 2016-2018 Challenge Area that focused on understanding the barriers and processes that prevented the adoption of technology and research results into sustainable practices.
