Photocontrol of boron metabolism in sea grasses.
Boron is taken up in the dark and is excreted in response to light by the leaves of the marine vascular plant, Halophila engelmannii Ascherson. This phenomenon makes possible the study of boron metabolism in a higher plant without the stress of boron deficiency. Dependence of boron excretion on photosynthetic CO(2) fixation suggests that an organoboron complex between boron and a newly formed carbon compound from photosynthesis is selectively excreted.
