Cryptochromes are blue-light receptors that mediate photoresponses in plants. The
genomes of most land plants encode two clades of cryptochromes, CRY1 and CRY2, which …

Abstract ELONGATED HYPOCOTYL5 (HY5), a member of the bZIP transcription factor
family, inhibits hypocotyl growth and lateral root development, and promotes pigment …

Many plants use information about changing day length (photoperiod) to align their
flowering time with seasonal changes to increase reproductive success. A mechanism for …

Ultraviolet-B (UV-B) radiation is an intrinsic fraction of sunlight that plants perceive through
the UVR8 photoreceptor. UVR8 is a homodimer in its ground state that monomerizes upon …

Evergreen conifers are champions of winter survival, based on their remarkable ability to
acclimate to cold and develop cold hardiness. Counterintuitively, autumn cold acclimation is …

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 …

Major cereal crops have benefitted from Green Revolution traits such as shorter and more
compact plants that permit high-density planting, but soybean has remained relatively …

Plant growth is coordinately controlled by various environmental and hormonal signals, of
which light and gibberellin (GA) signals are two critical factors with opposite effects on …

Grain weight is one of the most important components of grain yield and is controlled by
quantitative trait loci (QTLs) derived from natural variations in crops. However, the molecular …
