Differential effects of severe water stress on linear and cyclic electron fluxes through Photosystem I in spinach leaf discs in Co2-enriched air

Jia, Husen; Oguchi, Riichi; Hope, Alexander B; Barber, James; Chow, Wah S (Fred)

Description

Linear and cyclic electron fluxes through Photosystem I in 1% CO 2 were quantified in spinach leaf tissue under severe water stress. Using actinic light with a peak at 697 nm for preferential light absorption by Photosystem I while also stimulating Photosystem II to improve redox poising, the cyclic electron flux after 60 s of illumination was a substantial proportion (33-44%) of the total electron flux through PSI at irradiances up to ~1,070 μmol photons m-2 s-1. At the maximum irradiance, the...[Show more]
