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 ...
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 ...
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 ...
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 ...
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 ...
SPF45-related splicing factor for phytochrome signaling promotes photomorphogenesis by regulating pre-mRNA splicing in Arabidopsis
(National Academy of Sciences, 2017-08)
Light signals regulate plant growth and development by controlling a plethora of gene expression changes. Posttranscriptional regulation, especially pre-mRNA processing, is a key modulator of gene expression; however, the ...
Structural basis for the Pr-Pfr long-range signaling mechanism of a full-length bacterial phytochrome at the atomic level
(American Association for the Advancement of Science, 2021-11)
Phytochromes constitute a widespread photoreceptor family that typically interconverts between two photostates called Pr (red light-absorbing) and Pfr (far-red light-absorbing). The lack of full-length structures solved ...
Real-time tracking of phytochrome's orientational changes during Pr photoisomerization
(2012)
Photoisomerization of a protein bound chromophore is the basis of the light sensing and signaling responses of many photoreceptors. Z-to-E photoisomerization of the Pr Cph1Δ2 phytochrome has been investigated by polarization ...
Real-Time Tracking of Phytochrome's Orientational Changes During Pr Photoisomerization
(AMER CHEMICAL SOC, 2012)
Photoisomerization of a protein bound chromophore is the basis of the light sensing and signaling responses of many photoreceptors. Z-to-E photoisomerization of the Pr Cph1 Delta 2 phytochrome has been investigated by ...
Phytochrome B links the environment to transcription
(Oxford University Press, 2021-03)
Phytochrome B (phyB) senses the difference between darkness and light, the level of irradiance, the red / far-red ratio and temperature. Thanks to these sensory capacities, phyB perceives whether plant organs are buried ...
