Speaker: Prof. Murray Grant, School of Life Sciences, Gibbet Hill Campus, University of Warwick, United Kingdom
Time: 9:30 am
Day/Date: October 14th, 2019 (Monday)
Host: Prof. Chanhong Kim
Venue: No.1 Meeting room
 
Abstract:
Significant progress has been made over the past 25 years in identifying classical plant disease resistance genes, and subsequently components of plant basal defence –two key defence mechanisms deployed by plants. However, our knowledge of the dynamics of plant-pathogen interactions are limited, especially our understanding of how the host responds at the cellular level and how signals are communicated from point of perception to the rest of the plant. We take a multidisciplinary approach to dissect host responses to pathogens exploiting genetics, whole plant imaging, subcellular imaging and electrophysiological responses. This talk will look at the dynamics of the early molecular events underpinning two key defence responses; (i) the induction and subsequent suppression of plant basal immunity in Arabidopsis thaliana by virulent Pseudomonas syringae and (ii) the rapid early events in the initiation and propagation of systemic signals following gene-for-gene recognition. A core theme of the talk will be an emerging role for the chloroplast in plant-microbe interactions.
 
The seminar will be delivered in English.
