Light is a crucial environmental cue not only for photosynthetic energy production but also
for plant growth and development. Plants employ sophisticated methods to detect and …

Plants undergo a major physiological change as they transition from vegetative growth to
reproductive development. This transition is a result of responses to various endogenous …

Highlights•The COP1/SPA E3 ubiquitin ligase is a repressor of photomorphogenesis.•The
COP1/SPA complex targets photomorphogenesis-promoting factors for proteolysis.•Active …

COP1 and DET1 are among the first repressors of photomorphogenesis to be identified,
more than 20 years ago. Discovery of these repressors as conserved regulators of the …

Phytochromes function as red/far-red photoreceptors in plants and are essential for light-
regulated growth and development. Photomorphogenesis, the developmental program in …

Phytochromes are red (R)/far-red (FR) light photoreceptors that play fundamental roles in
photoperception of the light environment and the subsequent adaptation of plant growth and …

Anthocyanins are natural pigments that accumulate only in light‐grown and not in dark‐
grown Arabidopsis plants. Repression of anthocyanin accumulation in darkness requires the …

protein domains in COP1 and SPA proteins.•The structure of the COP1 WD-repeat domain …

Cryptochromes are blue light receptors that mediate light regulation of gene expression in
all major evolution lineages, but the molecular mechanism underlying cryptochrome signal …

Light is life for plants. To continuously assess and adapt to fluctuations in the quality and
quantity of this essential commodity, plants deploy sensory photoreceptors, including the …
