Dark Reversion of Phytochrome in Sinapis alba L.
Phytochrome in Sinapis alba L. (white mustard) seedlings undergoes both decay and reversion after an exposure to red light. This is typical of other crucifers and of dicotyledons in general. In the presence of sodium azide, decay is inhibited, and reversion continues at about the same rate as in buffer alone. The reversion has been demonstrated both in cotyledon plus hypocotyl hook and in hypoc...
متن کاملIn vitro phytochrome dark reversion process.
Thermal reversion of the far-red absorbing form of phytochrome to the red absorbing form in darkness has been investigated in crude and partially purified isolates from a number of etiolated and light grown higher plants. The influence of temperature, aging and urea on the rate of reversion was also determined.Phytochrome isolated from all higher plants underwent reversion. The reversion procee...
متن کاملPhosphorylation and dark reversion of phytochrome B.
Phytochrome B (phyB) is the main light receptor responsible for the shade avoidance response in mature plants. Like other phytochromes (phys), it alternates between the Pfr form and the Pr form. Upon activation by red light (causing the switch to the Pfr conformation), phys interact with various signaling partners and translocate from the cytoplasm to the nucleus, where they are found in struct...

متن کاملDark Reversion of Phytochrome in Lettuce Seeds Stored in a Water-saturated Atmosphere.
Dark reversion of the far red-absorbing form of phytochrome, which does not occur in dry lettuce (Lactuca sativa var. Grand Rapids) seeds, appears to take place in seeds stored in a water-saturated atmosphere. The water content (approximately 70% after 10 days) of such seeds is insufficient to support germination; however the treatment enhances germination in seeds stored for 1 to 5 days, but t...
