CCT1 — Pisum sativum

Summary

PsCCT1 (PSAT7G065040) on chromosome 7LG7 encodes a chaperonin belonging to the TCP-1/CCT family, with ATP-dependent protein folding chaperone activity, ubiquitin ligase activity, and ATP binding. It is associated with photoperiodic flowering, shade avoidance, circadian clock entrainment, and responses to light intensity and UV-B. The gene is linked to numerous traits including flowering time, anthocyanin content, seed maturation, stomatal movement, and responses to abiotic stresses such as salt, drought, and low temperature. It localizes to the cytosol, nucleus, and the Cul4-RING E3 ubiquitin ligase complex. Studies of related genes in other species connect the family to photomorphogenesis, light signaling, and stress tolerance.
