The timing of flowering affects the success of sexual reproduction. This developmental event
also determines crop yield, biomass, and longevity. Therefore, this mechanism has been …

COP1/SPA complex targets photomorphogenesis-promoting factors for proteolysis.•Active …

The plant hormone jasmonic acid (JA) is involved in the cold stress response, and the
inducer of CBF expression 1 (ICE1)‐C‐repeat binding factor (CBF) regulatory cascade plays …

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 terrestrialization brought forth the land plants (embryophytes). Embryophytes account
for most of the biomass on land and evolved from streptophyte algae in a singular event …

Plants sense different parts of the sun's light spectrum using distinct photoreceptors, which
signal through the E3 ubiquitin ligase COP 1. Here, we analyze why many COP 1 …

CONSTITUTIVE PHOTOMORPHOGENIC 1 functions as an E3 ubiquitin ligase in plants and
animals. Discovered originally in Arabidopsis thaliana, COP1 acts in a complex with SPA …

Light signals mediate a number of physiological and developmental processes in plants,
such as flowering, photomorphogenesis, and pigment accumulation. Emerging evidence …

As an important environment factor, light affects plant growth and development throughout
life. B-BOX (BBX) proteins play key roles in the regulation of light signaling. Although the …

In plants, the cryptochrome photoreceptors suppress the activity of the COP1/SPA ubiquitin
ligase to initiate photomorphogenesis in blue light. Both CRY1 and CRY2 interact with the …
