Lauren Ryder

Senior Postdoctoral Scientist and Research Manager
Nick Talbot Group

I completed my PhD in Molecular Genetics at The University of Exeter in 2009, working with Trichoderma hamatum for use as a crop stimulant and biocontrol agent in plant agriculture. My interest in plant pathology moved me to Professor Nick Talbot’s Molecular Genetics group as an associate research fellow, where I could study the mechanisms required for the rice blast fungus Magnaporthe oryzae to infect rice. I am particularly interested in answering fundamental questions regarding the processes underling appressorium mediated plant infection in M. oryzae. My research interests have largely focused on the role of superoxide-generating NADPH enzymes in the formation and function of appressoria and subsequent host penetration by the rice blast fungus. I am currently determining what signal(s) triggers cytoskeletal reorientation during appressorium development prior to host entry. This could potentially identify a novel and broad mechanism of appressorium mediated plant infection in other important cereal diseases.
