Deploying GABA metabolism to boost plant immunity to phytopathogens: From fundamental research to practical application

Aminobutyric acid (GABA) is a non-protein amino acid that has recently been discovered to play an important role in plant-pathogen interactions. In this proposal, we will comprehensively investigate the potential of GABA metabolism to boost plant immunity against fungal and bacterial pathogens using tomato and Arabidopsis as model plant systems. The effectiveness of exogenous applications of GABA will be compared with known inducers of disease resistance in laboratory and greenhouse trials, and then novel formulations will be developed and evaluated.
