11. The xanthophyll cycle, its enzymes, pigments and regulation
Abstract : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. Zeaxanthin has been implicated in the protection of the photosynthetic machinery from over-excitation. The enzyme violaxanthin de-epoxidase catalyses the conversion of violaxanthin to zeaxanthin.

12. Protein phosphorylation and proteolysis - regulation and adaptive responses in photosynthesis
Abstract : Just as all other organisms, plants adapt to various environmental conditions. This work focuses on the role of chloroplast light harvesting complex II, LHCII, in adaptation of photosynthesis to changed light conditions. READ MORE

13. Plant major intrinsic proteins - functional implications of expression and localisation studies
Abstract : Plant water channels are members of the very old Major Intrinsic Protein (MIP) family, with representatives in bacteria, fungi, animals, and plants. The genome of the model plant Arabidopsis thaliana contains 35 MIP genes. READ MORE

14. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways
Abstract : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. READ MORE

15. Violaxanthin De-epoxidase and the Xanthophyll Cycle
Abstract : The xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. READ MORE
