Phytochrome A mediates blue-light enhancement of second-positive phototropism in Arabidopsis [PDF]
, 2016 Hypocotyl phototropism of etiolated Arabidopsis seedlings is primarily mediated by the blue-light receptor kinase phototropin 1 (phot1). Phot1-mediated curvature to continuous unilateral blue light irradiation (0.5 µmol m-2 s-1) is enhanced by overhead ...

Cytoplasmic Phytochrome Action [PDF]
Plant and Cell Physiology, 2010 Phytochrome photoperception is a common mechanism for the detection of red and far-red light in bacteria, cyanobacteria, fungi and plants. However, the responses following phytochrome activation appear to be quite diverse between species. Lower plants, such as mosses, show phytochrome-mediated directional responses, namely phototropism and ...

Phytochrome-Interacting Proteins
Biomolecules, 2023 Phytochromes are photoreceptors of plants, fungi, slime molds bacteria and heterokonts. These biliproteins sense red and far-red light and undergo light-induced changes between the two spectral forms, Pr and Pfr. Photoconversion triggered by light induces conformational changes in the bilin chromophore around the ring C-D-connecting methine bridge and ...

Phytochrome A Mediates the Disassembly of Processing Bodies in Far-Red Light
Frontiers in Plant Science, 2022 Phytochromes are red- and far-red light receptors that control the growth and development of plants, enabling them to respond adequately to changing light conditions. It has been shown that halted mRNAs stored in RNA granules called processing bodies are

Phytochrome A Regulates Carbon Flux in Dark Grown Tomato Seedlings
Frontiers in Plant Science, 2019 Phytochromes comprise a small family of photoreceptors with which plants gather environmental information that they use to make developmental decisions, from germination to photomorphogenesis to fruit development.

Photoreversible interconversion of a phytochrome photosensory module in the crystalline state. [PDF]
, 2020 A major barrier to defining the structural intermediates that arise during the reversible photointerconversion of phytochromes between their biologically inactive and active states has been the lack of crystals that faithfully undergo this transition ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Interaction between the Circadian Clock and Regulators of Heat Stress Responses in Plants. [PDF]
, 2020 The circadian clock is found ubiquitously in nature, and helps organisms coordinate internal biological processes with environmental cues that inform the time of the day or year.

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light
Advanced Functional Materials, EarlyView.NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.
