Our research is focused on understanding, at the biochemical, molecular and cellular levels, how plants protect themselves against microbial pathogens. The major goal is to determine the mechanisms of action of salicylic acid (SA) in activation and regulation of the plant’s immune responses. We also are now employing the technology developed and knowledge gained from our work on SA and plant immunity to identify the targets of aspirin (acetyl SA) and its major metabolite SA in humans. The molecular/biochemical function of CRT1/MORC1 in multiple levels of plant immunity is also being deciphered. In addition, in collaboration with Frank Schroeder the induction of plant immune responses by nematode ascarosides is being investigated.
