Research interests:

A major type of plant defense against pathogen is inducible defense: i.e., defense mechanisms are turned on upon recognition of pathogen attack. Research in my group is directed towards understanding (1) how plants recognize pathogen attack and (2) how this recognition leads to induction of coordinated responses in plants. We use Arabidopsis and its bacterial pathogen Pseudomonas syringae as a model to study these problems. The type of resistance we study is called resistance (R) gene-mediated resistance. R gene-mediated resistance is usually strong and based on highly specific recognition of particular pathogen factors.

  1. How plants recognize pathogen attack.

    We try to elucidate how exactly this molecular recognition of pathogen factors is mediated by R gene products. We are also interested in determining the repertoire of recognition defined by the R gene family in Arabidopsis. We employ genetic, reverse-genetic, biochemical, genomic, and proteomic approaches for these objectives.
  2. How this recognition leads to induction of coordinated responses in plants.

    Our ultimate goal in this area is to understand the signaling mechanisms involved well enough to build a quantitative model for this signaling system. However, the signaling mechanisms are complex, and information we can obtain by conventional approaches is quite limited. Our major way to collect data from the signaling system is combining a large scale reverse genetics and massive phenotyping enabled by mRNA expression profiling. Based on this type of data, we elucidate complex relationships among the components involved in the system using a computational approach. We are also tapping into natural diversity among Arabidopsis accessions using genomic technologies to identify novel components of the system.
  3. Other projects:

    • Protein transfer from a fungal pathogen into the host plant cell.
    • Host factors that help bacterial virulence factors.
    • Computational biology, such as applications of nonlinear multivariate analysis to expression profile analysis and evolution within a single species, improvement of microarray data processing, methods for rapid and rough QTL mapping, etc.
