Genetic resistance to mycotoxin-producing fungi is the most cost-effective means of reducing these impacts, but there are currently no varieties of corn with this resistance. 2Blades researchers, led by Dr. Josiah Mutuku, are bringing new insights and cutting-edge tools to advance strong, long-lasting resistance to these fungi.
The researchers are using new gene discovery platforms to analyze thousands of plant cell surface receptor proteins. These proteins can bind molecules that may reveal the presence of the fungus to the plant. Upon detection of the invader, the plant can mount an immune response that prevents fungal growth and mycotoxin production. The genes for these proteins will then be transferred to corn to generate resistant crops.
This scientific research is enabling food systems and supply chains to be more resilient. By developing corn varieties resistant to toxic fungi production costs will be lower, and both grain quality and yield will be preserved, which helps to increase the income of growers. This is a significant step to continue to ensure there is safe food for all.
