CTR1 — Arabidopsis thaliana

Summary

AT5G03730 (CTR1) in Arabidopsis thaliana encodes a protein with dual-specificity protein kinase, histidine kinase, and serine/threonine protein kinase activities, and possesses a Ser/Thr kinase catalytic domain. CTR1 is associated with ethylene signal transduction, nitrate deficiency response, lateral root angle, anthocyanin accumulation, nitrogen metabolism, iron acquisition, endoreduplication, salinity and drought tolerance, and boron-mediated root development. It localizes to the ER membrane, cytosol, cytoplasm, and nucleus, and is linked to processes including translation reinitiation, flavone metabolism, stem cell renewal, lateral root branching, xanthophyll cycle, long-chain fatty acid metabolism, epidermis development, response to gravity and singlet oxygen, detection of ethylene stimulus, and jasmonic acid/ethylene-dependent systemic resistance. Associations with yield, grain weight, tiller number, root hair density, bacterial disease response, submergence tolerance, fruit ripening, and temperature stress response have also been noted. Related genes in other species are linked to fruit ripening, disease resistance, and oxidative stress response.
