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 ...
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). ...
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 ...
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 ...
Arabidopsis thaliana HomeoBox 1 (AtHB1), a Homedomain-Leucine Zipper I (HD-Zip I) transcription factor, is regulated by PHYTOCHROME-INTERACTING FACTOR 1 to promote hypocotyl elongation
(Wiley Blackwell Publishing, Inc, 2015-08)
Arabidopsis thaliana HomeoBox 1 (AtHB1) is a homeodomain-leucine zipper transcription factor described as a transcriptional activator with unknown function. Its role in A. thaliana development was investigated. AtHB1 ...
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 ...
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 ...
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 ...
Thermomorphogenesis
(Annual Reviews, 2019-04)
When exposed to warmer, nonstressful average temperatures, some plant organs grow and develop at a faster rate without affecting their final dimensions. Other plant organs show specific changes in morphology or development ...
Functional convergence of growth responses to shade and warmth in Arabidopsis
(Wiley Blackwell Publishing, Inc, 2021-04)
Shade and warmth promote the growth of the stem, but the degree of mechanistic convergence and functional association between these responses is not clear. We analysed the quantitative impact of mutations and natural genetic ...
