Three major viruses, Alfalfa mosaic virus (AMV), Bean pod mottle virus (BPMV) and Soybean mosaic virus (SMV), cause significant losses in the yield and quality of soybean seeds in Ohio. With support from OSC and other sources, we have carried out studies to generate transgenic soybeans that confer resistance to all three viruses with one single transgene construct. Greenhouse studies have identified three independent lines that confer strong resistance to simultaneous infections of all three viruses. This project involves further testing of these three transgenic soybean lines in experimental fields for their resistance to the three viruses. Successful completion of this project will lay...
