Effects of High Light Stress on Carotenoid-Deficient Chloroplasts in Pisum sativum.

abstract：:The development of photochemical activity in relation to pigment and membrane protein accumulation in chloroplasts of greening wild-type barley (Hordeum vulgare L. cv. Gateway) and its virescens mutant were studied. The rate of chlorophyll accumulation per plastid was faster in the wild-type than in the mutant seedlin...

abstract：:The mechanism of photoactivation of photosystem I electron transport was studied in intact Bryopsis corticulans chloroplasts. The evidence from chemical and photochemical studies suggests that photoactivation is a consequence of a reduction of an electron transport component, presumably ferredoxin-NADP(+) reductase. O...
