From past OSC support we have used a new technology, gene silencing, to identify the key soybean genes involved in soybean resistance to Phytophthora sojae. A few critical genes, including PR-1a and PR-2, were found to be master control genes for the expression of all the forms of resistance to Phytophthora. In the work proposed here, we will move this research into the next phase. First of all, we will extend our findings to PR-3, which we believe will function as a master control gene for a broad spectrum of other fungal pathogens of soybean. We then wish to determine if over-expression of these three master genes in soybean will actually confer enhanced broad spectrum resistance to...
