TCP — Cucumis sativus

Summary

CsTCP (CSA_5G644550) on cucumber chromosome 5 encodes a chaperonin belonging to the TCP-1 family, with ATP-dependent protein folding chaperone activity and ATP hydrolase activity. It is associated with diverse biological processes including zeatin and hormone anabolism, auxin transport, meristem and floral organ development, leaf morphogenesis, seed germination, protein refolding, and response to zinc. The gene product localizes to the cytosol, nucleus, plastid, mitochondria, and the TriC complex. Associations with selenium and sulfur content, leaf size, and organ identity have been noted. Studies of related genes in other species link the TCP-1 family to peroxisomal protein import, glyoxysomal function, cadmium tolerance, and nitric oxide production, as well as traits such as seed weight, fruit weight and shape, leaf length, chlorophyll content, and cytokinin and auxin content.
