Outline of Research and Education
In nature, plants cope with a wide range of microbes that reside on the surface of or within plant tissues. Plants disregard or tolerate the presence of these plant-inhabiting endophytic microbes at non-damaging levels, despite an elaborate innate immune system to detect and repel microbes. We hypothesize that plants distinguish pathogens from non-pathogens by sensing “danger” signals (DAMPs) generated upon pathogen challenge in addition to microbial signals (MAMPs). We aim to decipher the molecular principles and mechanisms underlying plant immunity to infectious microbes, with major focuses on signaling crosstalk between MAMP and DAMP receptors, defense-related transcriptional reprogramming and infection strategies of pathogenic and endophytic microbes. We also study the mechanisms by which a subset of endophytic microbes facilitates host adaptation to adverse conditions. We believe that our studies will reveal important insight into general principles of plant-microbe interactions, and thus offer new effective approaches to controlling plant health and growth in sustainable agriculture.
