ABSTRACT
The aim of this monograph is to highlight various mechanisms followed by plants to overcome the high light stress and photoinhibition, and also the plant responses to low light levels. Emphasis has been on the regulation of light harvesting process, the avoidance phenomena at leaf and chloroplast levels and the strategy followed by certa in solar t

mutants are qualitatively similar to results obtained with equivalent mutants of Chlamydomonas. Structural and photophysical similarity has been noticed between Z and lutein. It is, therefore, possible that some lutein molecules bound to PS II protein perhaps PsbS may play a direct role in the ApH and xanthophyll dependant NPQ. The roles of xanthophylls in photoprotection has been
