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 thaliana and its bacterial pathogen Pseudomonas syringae as a model to study these problems. The type of resistance we mainly 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.

How plants recognize pathogen attack.
We try to elucidate how exactly this molecular recognition of pathogen factors is mediated and how signaling of this recognition is initiated by R gene products. We are also interested in determining the repertoire of recognition specificity defined by the R gene family (NB-LRR genes) in Arabidopsis. Furthermore, we are investigating whether members of the R gene family have any roles in other types of resistance mechanisms. We employ genetic, reverse-genetic, biochemical, genomic, and proteomic approaches for these objectives.

How this recognition leads to induction of coordinated responses in plants.
Our ultimate goal in this area is to understand the signaling mechanisms well enough, so that we will be able to build a quantitative model for this signaling network on computer. However, the topology of the signaling network is 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, quantitative phenotyping enabled by mRNA expression profiling. Based on this type of data, we will elucidate complex relationships among the components involved in the network using a computational approach. We are also tapping into natural variation among populations of Arabidopsis using genomic technologies to discover novel components of the network. Furthermore, we are trying to shut down the entire signaling network and reconstitute it with one component at a time - with this technology, we will be able to collect data that are much easier to interpret for the purpose of elucidating the signaling network.

Computational biology and Bioinformatics.
We are integrating computational approaches to experimental approaches to facilitate our discovery.The small-scale microarray we developed for mRNA expression profiling uses a model-based statistics and a novel normalization method to enable accurate measurement.We are building a database that allows recording and statistical analysis of metadata, as well as the mRNA expression profiles and other experimental data. We apply nonlinear multivariate analysis to infer the signaling network topology.We are developing a rapid QTL mapping method for the purpose of discovering novel components of the network.
