Photosynthetic HCO3− Utilization and OH− Excretion in Aquatic Angiosperms: LIGHT-INDUCED pH CHANGES AT THE LEAF SURFACE 1
AUTOR(ES)
Prins, Hidde B. A.
RESUMO
The utilization of HCO3− as carbon source for photosynthesis by aquatic angiosperms results in the production of 1 mole OH− for each mole CO2 assimilated. The OH− ions are subsequently released to the medium. In several Potamogeton and Elodea species, the site of the HCO3− influx and OH− efflux are spatially separated. Described here are light- and dark-induced pH changes at the lower and upper epidermis of the leaves of Potamogeton lucens, Elodea densa, and Elodea canadensis.
