ST. LOUIS & EVANSTON, Ill.–Monsanto Company and charitable organization 2Blades Foundation (2Blades) have formed a new collaboration to discover novel sources of genetic resistance to Asian soybean rust (ASR). 2Blades will deliver resistance genes in further collaboration with The Sainsbury Laboratory (TSL, Norwich, UK), the leading global institute for research on plant-pathogen interactions, and the Universidade Federal de Viçosa (UFV), a leading university in agricultural sciences in Brazil.
Asian soybean rust, a disease caused by the fungus Phakopsora pachyrhizi, results in yellowing and browning of soybean leaves and can lead to premature senesence and significant yield loss. According to the U.S. Department of Agriculture (USDA), P. pachyrhizi has spread rapidly and causes yield losses from 10 to 80% in Argentina, Asia, Brazil, Paraguay, South Africa, and Zimbabwe.1
“Asian soybean rust is an ugly and expensive disease that can devastate farmers’ harvests,” said Jeremy Williams, Monsanto’s biotechnology and ag productivity innovation lead. “Current fungicide treatments can provide some control, but farmers need more tools – and the 2Blades research could help provide a durable solution as part of an integrated pest-management system.”
2Blades’ mission is to contribute to global food security by developing crops with long-lasting resistance to pathogens in order to reduce losses due to disease. By working with world-leading plant scientists, 2Blades seeks to discover new sources of disease resistance in nature and transfer them into important crops to extend the breadth of their immune system and secure yields.
“Collaboration with industry is vital to ensure that new discoveries made in the lab can lead to innovations that will prevent crop losses caused by plant disease,” said Dr. Peter van Esse, leader of the 2Blades Research Group at TSL. “It is therefore exciting to see that our scientific expertise and knowledge on plant-microbe interactions will be combined with Monsanto’s capacity to deliver solutions to farmers to tackle a key challenge in soybean cultivation.”
“The management of soybean rust requires the integration of different approaches, including disease resistance. This collaboration will allow us to use cutting-edge technologies to speed up the identification of new resistance genes that can be used to deliver more sustainable solutions to soybean farmers, reducing the environmental and economic impact of ASR,” said Prof. Sérgio H. Brommonschenkel at UFV.
In January 2017, Monsanto, 2Blades and The Sainsbury Laboratory announced a collaboration focused on tackling corn disease complexes such as stalk and ear rots that have the potential to significantly reduce yield. That research is ongoing and is independent of this new collaboration.
The ASR collaboration complements Monsanto’s work to expand the global crop protection toolbox while enabling farmers to produce more with less of an impact on the environment. 2Blades retains rights to deploy new leads arising from the program in crops for smallholder farmers in the least developed countries, with a particular focus on sub-Saharan Africa. Soybean is a crop of significant and increasing importance in Africa, with extraordinary nutritional, soil, and economic benefits. However, the presence of ASR throughout the African continent is a major factor limiting production.
