Functional Genomics of Plants

Functional genomics, bioinformatics, and DNA chip technology are fundamentally changing research on biological systems. Knowledge of complete genome sequences and high resolution genome technology provide an extraordinary opportunity to understand complex biological processes and to relate detailed understanding of protein structure and biochemical mechanism to the function of whole organisms and biological systems in nature.

Our research team is helping to build genome maps and DNA diagnostic microarrays/chips for analysis of global gene expression and biodiversity. This new technology is being used to explore the molecular basis of several fundamental plant responses: (1) light responsive genetic systems that help protect plants from damage by high intensity UV/blue light; (2) genetic systems that allow plants to adapt to the environment; (3) genes and signal transduction pathways that help protect plants from insects and disease; and (4) genes that regulate plant development (flowering time, fertility restoration, chloroplast development/number).
