Rice is a model plant for monocots and one of the most important food crops for over half of the world's population. Rice blast (Magnaporthe oryzae) and sheath blight (Rhizoctonia solani) are the two most destructive diseases that negatively affect world-wide rice production. My research program aims to understand the molecular mechanism of pathogen virulence and host immunity during the rice-fungus interaction, and to translate new genomic knowledge into agricultural productivity via biotechnology. Our current research activities involve the following areas:
1. Pathogen virulence: Our recent studies focus on molecular, biochemical and functional characterization of the fungal effectors and their corresponding host protein targets. For example, the Nep1-like toxins and the zinc-finger effectors from Magnaporthe oryzae were found to interfere with host protein degradation or manipulate host chromatin configuration and gene expression, respectively. Using the yeast two-hybrid assay, in vitro protein binding, in vivo co-immunoprecipitation, bimolecular fluorescence complementation, and transgenic analyses, we have been elucidating the mode of action of the fungal effectors and characterizing the host target complexes for the underlying mechanism of pathogenesis and host susceptibility.
2. Host immunity: Our previous studies on rice defense signaling pathways reveal the distinctive roles of salicylic acid (SA), jasmonic acid (JA), ethylene (ET) and abscisic acid (ABA) in mediating rice resistance to different pathogens. The cross-talk between jasmonate and gibberellin pathways was shown to play an important role in rice growth and defense response. Using a combination of molecular, biochemical, physiological and functional genomic approaches, a number of stress-responsive rice mitogen-activated protein kinases (MAPKs) were found to modulate hormone signaling and mediate cross-talks between disease resistance and abiotic stress tolerance. To gain novel insights into the rice protein kinase signal transduction, we have been characterizing many substrates of the stress-responsive MAPKs and calcium-dependent protein kinases (CDPKs) and determining the role of the MAPK-CDPK cross-talk in rice biotic and abiotic stress tolerance.
3. Translational biotechnology: Based on the mechanistic studies of pathogen virulence and host immunity, we have generated genetically modified rice crop with enhanced disease resistance and/or abiotic stress tolerance. Recently, the bacterial CRISPR-Cas9 system has been adapted in my laboratory for plant genome editing and precision breeding of transgene-free, genetically improved crops such as rice, potato and mushroom. A series of plasmid vector systems (see www.addgene.org) and bioinformatic tools (www.genome.arizona.edu/crispr) have been developed by our group to facilitate the application of CRISPR-Cas9 editing technology in plant genome engineering and crop improvement.
