Uptake of potassium (K) and (86)rubidiumlabelled potassium ((86)Rb) by sub-hypocotyl hook sections of Phaseolus aureus L. was inhibited by red light. The effect was reversible with far red light. Using short exposures of high irradiance the effect on (86)Rb-labelled K uptake was observed after 5 min
The opening of the hypocotyl hook in bean seedlings is due to a rapid elongation of cells on the inner side of the hook elbow. Red light promotes hook opening by inducing this cell elongation.Opening is inhibited by low concentrations of indoleacetic acid (IAA) and 2,4-dichlorophenoxyacetic acid (2,
