Ethylene-independent promotion of photomorphogenesis in the dark by cytokinin requires COP1 and the CDD complex [PDF]

, 2019
The transition of skotomorphogenesis to photomorphogenesis is induced by the perception of light, and is characterized by the inhibition of hypocotyl elongation and opening of cotyledons.

Interactions of drosophila cryptochrome

Photochemistry and Photobiology
AbstractIn this study, we investigate the intricate regulatory mechanisms underlying the circadian clock in Drosophila, focusing on the light‐induced conformational changes in the cryptochrome (DmCry). Upon light exposure, DmCry undergoes conformational changes that prompt its binding to Timeless and Jetlag proteins, initiating a cascade crucial for ...

Veinal Necrosis Induced by Turnip mosaic virus Infection in Arabidopsis Is a Form of Defense Response Accompanying HR-Like Cell Death

Molecular Plant-Microbe Interactions, 2008
In the pathosystems of Turnip mosaic virus (TuMV) with Brassicaceae crops, various symptoms, including mosaic and necrosis, are observed. We previously reported a necrosis-inducing factor TuNI in Arabidopsis thaliana, a model species.

Multiple roles for UV RESISTANCE LOCUS8 in regulating gene expression and metabolite accumulation in arabidopsis under solar ultraviolet radiation [PDF]

, 2013
Photomorphogenic responses triggered by low fluence rates of ultraviolet B radiation (UV-B; 280–315 nm) are mediated by the UV-B photoreceptor UV RESISTANCE LOCUS8 (UVR8).

Reversible Lichtinduzierte Oligomerisierung von Arabidopsis‑Cryptochrom 1 und Antagonismus durch BIC1: Einblicke durch Zeitaufgelöste Native Massenspektrometrie

Angewandte Chemie, EarlyView.
Mittels zeitaufgelöster nativer Massenspektrometrie wird der blaulichtabhängige kinetische Mechanismus der Oligomerisierung von Arabidopsis CRY1 aufgedeckt. Die Oligomerisierung verläuft sequenziell von Monomeren über Dimere zu Tetrameren. Während ATP die Assemblierung fördert, inhibiert BIC1 die Tetramerbildung und dissoziiert diese unabhängig von ...

UV Radiation in DNA Damage and Repair Involving DNA-Photolyases and Cryptochromes

Biomedicines, 2021
Prolonged exposure to ultraviolet radiation on human skin can lead to mutations in DNA, photoaging, suppression of the immune system, and other damage up to skin cancer (melanoma, basal cell, and squamous cell carcinoma).

Antagonistic Regulation of Circadian Output and Synaptic Development by JETLAG and the DYSCHRONIC-SLOWPOKE Complex [PDF]

, 2020
Circadian output genes act downstream of the clock to promote rhythmic changes in behavior and physiology, yet their molecular and cellular functions are not well understood. Here we characterize an interaction between regulators of circadian entrainment,

Comparative transcriptomic analysis unveils interactions between the regulatory CarS protein and light response in Fusarium [PDF]

, 2019
Background The orange pigmentation of the agar cultures of many Fusarium species is due to the production of carotenoids, terpenoid pigments whose synthesis is stimulated by light.

The action mechanisms of plant cryptochromes [PDF]

Trends in Plant Science, 2011
Cryptochromes (CRY) are blue-light receptors that mediate various light responses in plants. The photoexcited CRY molecules undergo several biophysical and biochemical changes, including electron transfer, phosphorylation and ubiquitination, resulting in conformational changes to propagate light signals.

Time‐Resolved Native Mass Spectrometry Reveals Reversible Light‐Driven Oligomerization of Arabidopsis Cryptochrome 1 and Its Antagonism by BIC1

Angewandte Chemie International Edition, EarlyView.
Time‐resolved native mass spectrometry uncovers the blue‐light‐dependent kinetic mechanism of Arabidopsis CRY1 oligomerization, proceeding sequentially from monomers to dimers and tetramers. ATP promotes assembly, whereas BIC1 actively blocks and disassembles tetramers independent of light, providing mechanistic insight into the regulation of ...
