CAR1 — Brassica oleracea var. botrytis

Summary

BoCAR1, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with a C2 domain that is associated with kinase regulator activity, protein phosphatase inhibitor activity, GAP activity, signaling receptor activity, and phospholipid binding. This gene is associated with the upregulation of abscisic acid (ABA)-mediated signaling, jasmonic acid (JA) signaling, defence response to bacteria, salinity response, and response to wounding. It has been linked to numerous agronomic traits including seed yield, water use efficiency, transpiration rate, stomatal resistance and closure, anthocyanin content, leaf senescence, root thickness and lateral root length, vegetative growth time, and tolerance to high and low temperature stress, osmotic stress, and disease. The protein localizes to multiple cellular compartments including the tonoplast, plastid, mitochondria, cytosol, plasmalemma, and nucleus.
