CAR1 — Brassica oleracea var. botrytis

Summary

BoCAR1, located on cauliflower chromosome 4, encodes a protein with a C2 domain and multiple regulatory activities, including kinase regulator activity, protein phosphatase inhibitor activity, and GAP activity, as well as phospholipid and lipid binding. It is associated with the upregulation of GTPase activity, activation of defence response to bacteria, upregulation of abscisic acid-mediated signaling, jasmonic acid signaling, salinity response, and response to wounding. The protein localises to the tonoplast, plastid, mitochondria, cytosol, plasmalemma, cytoplasm, and nucleus. BoCAR1 is linked to transpiration rate, water use efficiency, stomatal resistance, seed yield, vegetative growth time, lateral root length, root thickness, anthocyanin content, leaf senescence, and high and low temperature stress response, osmotic response sensitivity, and disease tolerance. Related genes in other species connect the family to abscisic acid signaling, drought response, and transpiration.
