Persistent Photoreversibility of Leaf Development
Year: 1969
Type: article
Abstract: Far red light reversal of red light induced leaf expansion and enzyme changes were investigated in seedlings of Phaseolus vulgaris var. Black Valentine. In etiolated plants growth, anthocyanin accumulation and increases in glyceraldehyde-3-phosphate dehydrogenase and glycolic acid oxidase activities induced by a 10 min red irradiation were stopped by a 7 min far red irradiation given 17, 24, or 48 hr after activation. Etiolated seedlings illuminated for 24 hr with white light and seedlings grown in continuous light remained sensitive to far red reversal. This suggests that the far red sensitive receptor does not decay with time but remains associated with the site of its regulatory functions.
