Understanding these mechanisms will help in developing crop plants that are able to thrive even under harsh environmental conditions. Currently we are focusing our studies on a family of four high light inducible polypeptides (HLIP) with similarity to the light harvesting chlorophyll a/b-binding proteins of vascular plants in the cyanobacterium Synechocystis sp. PCC 6803. These polypeptides accumulate under a variety of stress conditions and they are required for surviving exposure to high intensity light. The exact mechanism of HLIP action and the function of the polypeptides in survival during high light exposure are not clearly understood. HLIPs are preserved in vascular plants; they may play important roles in these systems as well. The regulatory mechanism that governs the expression of the genes encoding HLIPs (hli) has not yet been elucidated. Several important questions are being addressed. These include how hli genes are regulated, whether HLIPs form complexes, and what are the roles of HLIPs in cell survival. The approaches being used combine genomics, proteomics and bioinformatics tools.   .   .
