Phytochrome A is an irradiance-dependent red light sensor.

The Plant journal : for cell and molecular biology - 1 Apr 2007

Franklin Keara A, Allen Trudie, Whitelam Garry C

Abstract excerpt

Plants perceive red (R) and far-red (FR) light signals using the phytochrome family of photoreceptors. In Arabidopsis thaliana, five phytochromes (phyA-phyE) have been identified and characterized. Unlike other family members, phyA is subject to rapid light-induced proteolytic degradation and so accumulates to relatively high levels in dark-grown seedlings. The insensitivity of phyA mutant seedlings to prolonged...
