Elucidating the molecular basis of plant potyvirus resistance

Plant viruses are responsible for a large proportion of crop losses, and genetic resistance is currently the most effective means to control viral spread. This project investigates, on a molecular and structural level, host factors that plant viruses hijack during infection, and in particular, the mutations in these factors that confer resistance. We further aim to elucidate the mechanisms by which plant viruses overcome resistance mediated by these host factors. A detailed understanding of the molecular interactions between plant viruses and their host will enable new, robust and more effective forms of resistance to be engineered. This work therefore has economic and environmental implications for agricultural productivity in Australia.
