Abstract
Plants have mechanisms to acclimate to high-light conditions by extinction of the excess light energy. These mechanisms are important for plant to efficiently perform photosynthesis, and have to be controlled accurately. However, detailed mechanisms how plants diminish excess light energy are still unclear.Here we report a novel gene named LAP1(Light Acclimation Protein 1),that is involved in the high-light acclimation response in plants. Arabidopsis lap1 mutant displayed a pale green phenotype with higher NPQ values than those of wild type. We currently characterize lap1 mutant of synechocystis sp.PCC 6803.Together with these results, physiological function of LAP1 will be discussed in this presentation.
