CAR1 — Brassica oleracea var. botrytis

Summary

BoCAR1, located on chromosome 6 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with kinase regulator activity, protein phosphatase inhibitor activity, and GAP activity, and it contains a C2 domain. The gene is associated with upregulation of GTPase activity, activation of defence response to bacteria, upregulation of abscisic acid mediated signaling, upregulation of response to thirst, activation of salinity response, JA signaling, response to wounding, salinity response, response to abscisic acid, and defense response. It is linked to traits such as transpiration rate, adventitious rootless, seed yield trait, jasmonic acid sensitivity, osmotic response sensitivity, water use efficiency, vegetative growth time, stomatal resistance, lateral root length, plant stress response trait, jasmonic acid content, high temperature stress response, abiotic plant stress response trait, anthocyanin content, stomatal complex closure time, low temperature stress response, stomatal opening, leaf senescence trait, root thickness, disease tolerance, and plant growth and development trait. The protein localizes to multiple cellular compartments including the tonoplast, plastid, mitochondria, cytosol, plasmalemma, cytoplasm, and nucleus. Studies of related genes in other species connect the family to ABA signaling, drought response, and seed dormancy.
