The research in my laboratory is aimed at elucidation of the molecular circuitry used by plants in response to environmental stress. This enables the identification of key components which would help in their targeted manipulation in transgenic plants. Our efforts to address these involve utilization of a repertoire of approaches, which include physiochemical, proteomic and genomic tools. Recent advances in proteomics have created an opportunity for dissecting quantitative and qualitative traits in a more meaningful way. The proteomics approach is ideally suited for fast and sensitive analysis of the functions of the plant genes and gene-products, the proteins. Our research interest can be grouped under two thrust areas: stress proteomics, and gene expression and regulation.

STRESS PROTEOMICS

The application of proteomics technologies to advance our knowledge of stress tolerance in crop species has increased dramatically in the past few years. We are focusing on subcellular proteomics and using a number of proteome mining tools to understand the role of protein modifications and/or their differential expression under stress conditions. We have developed differential proteomes in response to various environmental stresses. The major focus is to discover the regulatory genes that control stress tolerance in crop plants, which would not only aid in elucidation of the underlying mechanism(s) of stress tolerance, but also serve as a valuable resource for engineering strategies towards improved stress adaptation.

GENE EXPRESSION AND REGULATION

Stress tolerance is a quantitative trait determined by multiple and complex genetic interactions. Plant response to stress involves changes in the expression of thousands of genes, which in turn are affected by complex interactions with the environment, beyond the stress of interest. To better understand the interdependent action of an array of genes, my group has been working on several crop species, owing to the variable degree of tolerance among cultivars. This approach provides correlative evidence for genes involved in stress adaptation. While our research has shown the involvement of several novel genes in stress physiology, the richness of the candidate genes points to the enormity of the complexity to be deciphered for understanding the stress-responsive network.
