Photoreceptor Signaling Networks in Plant Responses to Shade
(Annual Reviews, 2013-04)
The dynamic light environment of vegetation canopies is perceived by phytochromes, cryptochromes, phototropins, and UV RESISTANCE LOCUS 8 (UVR8). These receptors control avoidance responses to preclude exposure to limiting ...
Shade Promotes Phototropism through Phytochrome B-Controlled Auxin Production
(Cell Press, 2016-12)
Phototropism is an asymmetric growth response enabling plants to optimally position their organs. In flowering plants, the phototropin (phot) blue light receptors are essential to detect light gradients. In etiolated ...
Multiple links between shade avoidance and auxin networks
(Oxford University Press, 2018-01)
Auxin has emerged as a key player in the adjustment of plant morphology to the challenge imposed by variable environmental conditions. Shade-Avoidance responses, including the promotion of stem and petiole growth, leaf ...
Shade Avoidance
(American Society of Plant Biologists, 2012-01)
The presence of neighboring vegetation modifies the light environment experienced by plants, generating signals that are perceived by phytochromes and cryptochromes. These signals cause large changes in plant body form and ...
Perception and signalling of light and temperature cues in plants
(Wiley Blackwell Publishing, Inc, 2017-05-23)
Light and temperature patterns are often correlated under natural plant growth conditions. In this review, we analyse the perception and signalling mechanisms shared by both these environmental cues and discuss the functional ...
Convergence of constitutive photomorphogenesis 1 and phytochrome interacting factor signalling during shade avoidance
(Wiley, 2016-04)
Shade-avoidance responses require CONSTITUTIVE PHOTOMORPHOGENESIS 1 (COP1) but the mechanisms of action of COP1 under shade have not been elucidated. Using simulated shade and control conditions, we analysed: the transcriptome ...
Light perception and signalling by phytochrome A
(Oxford University Press, 2014-06)
In etiolated seedlings, phytochrome A (phyA) mediates very-low-fluence responses (VLFRs), which initiate de-etiolation at the interphase between the soil and above-ground environments, and high-irradiance responses (HIR), ...
Phytochrome A Antagonizes PHYTOCHROME INTERACTING FACTOR 1 to Prevent Over-Activation of Photomorphogenesis
(Oxford University Press, 2014-09)
Phytochrome A (phyA) is crucial to initiate the early steps of the transition between skoto- and photomorphogenesis upon light exposure and to complete this process under far-red light (typical of dense vegetation canopies). ...
Regulation of flowering time by light
(Research Signpost, 2011)
To predict the arrival of the favorable season, plants monitor environmental variables such as light and temperature. Light is perceived by several families of photoreceptors, the phytochromes, the cryptochromes and the ...
Phytochrome b nuclear bodies respond to the low red to far-red ratio and to the reduced irradiance of canopy shade in Arabidopsis
(American Society Of Plant Biologist, 2014-08)
The current consensus is that plant responses to canopy shade involve the perception of low red to far-red ratios (R:FRs) by phytochrome B (phyB), which leads to the direct activation of auxin synthesis genes by PHYTOCHROME ...
