Apr 12, 2010 · CONSTANS is an evolutionarily-conserved central component of the genetic pathway that controls the onset of flowering in response to daylength. However, the specific biochemical mechanism by which the CONSTANS protein regulates the expression of its target genes remains largely unknown. •

Feb 13, 2004 · We show that light stabilizes nuclear CO protein in the evening, whereas in the morning or in darkness the protein is degraded by the proteasome. Photoreceptors regulate CO stability and act antagonistically to generate daily rhythms in CO abundance.

Jan 14, 2011 · The role, extent, and association between ancient redox and photoperiod control of gene and protein expression are extremely interesting but beyond the scope of this review. Another layer of control ensures that transcription factors that activate photosynthetic genes are degraded during the night.

Sep 22, 2023 · CONSTANS protein, Arabidopsis. DNA-Binding Proteins. CONSTANS (CO) is a critical regulator of flowering that combines photoperiodic and circadian signals in Arabidopsis (Arabidopsis thaliana). CO is expressed in multiple tissues, including seedling roots and young leaves.
constans (CO mutant) LD and SD plants. However, seed size is smaller compared with plants grown under their preferred photoperiods. The broken line arrows show an increase (upward arrow) and a decrease (downward arrow) in protein levels. The unbroken arrow represents positive regulation and the bar represents negative regulation.
