TL;DR: It is demonstrated that the phytochrome B (phyB) photoreceptor participates in temperature perception through its temperature-dependent reversion from the active Pfr state to the inactive Pr state, and proposed that in addition to its photorecept functions, phyB is a temperature sensor in plants.
Journal ArticleDOI
Molecular mechanisms underlying phytochrome-controlled morphogenesis in plants
TL;DR: Current models of phytochrome function connecting light-induced conformational changes to physiological outputs are reviewed, to highlight open questions for future research and compare and contrast phy tochrome responses and signaling mechanisms among land plants.
Journal ArticleDOI
Perception and signalling of light and temperature cues in plants
TL;DR: The sharing of mechanisms of action for two distinct environmental cues is to some extent unexpected, as it renders these responses mutually dependent, and many ecological contexts in which such a mutual influence could be beneficial.
Journal ArticleDOI
Rapid Decline in Nuclear COSTITUTIVE PHOTOMORPHOGENESIS1 Abundance Anticipates the Stabilization of Its Target ELONGATED HYPOCOTYL5 in the Light
TL;DR: The classic view is challenged that the migration of the repressor of photomorphogenesis COP1 from the nucleus to the cytoplasm is too slow to participate in light-mediated developmental events.
Journal ArticleDOI
COP1 re-accumulates in the nucleus under shade.
TL;DR: It is shown that in Arabidopsis thaliana, COP1 accumulates in the nucleus under natural or simulated shade, despite the presence of far-red light, which is consistent with a signalling role of COP1 in shade avoidance.
