Phytochrome-controlled Hydrogen Ion Excretion by Avena Coleoptiles
Year: 1977
Type: article
Abstract: A red light-induced, far red reversible stimulation of proton efflux from apical segments of etiolated Avena sativa L. cv. Victory coleoptiles was observed. The acidification responses to red light and also to auxin were not the consequence of respired CO(2). The response to red light was strongly inhibited by cycloheximide and carbonyl cyanide, m-chlorophenyl hydrazone, but mannitol had a stimulatory effect. Red light and auxin applied together yielded a greater than additive response, in comparison to the effects of the two stimuli applied separately.
