CYP707A1 — Brassica oleracea

Summary

BoCYP707A1 on cabbage chromosome 2 encodes a cytochrome P450 monooxygenase with abscisic acid 8'-hydroxylase activity, placing it in the CYP707A family. The gene is associated with abscisic acid breakdown, response to abiotic stimulus, release of seed from dormancy, sterol metabolism, chlorophyll breakdown, brassinosteroid homeostasis and anabolism, response to red or far-red light, response to AOS, MAPK cascade, response to thermal stimulus, response to hypoxia, NO storage, microtubule bundling, skotomorphogenesis, homeostasis, and fruit ripening. It is linked to chlorophyll content, stomatal density, rehydration response, abscisic acid metabolism, stomatal closure, seed dormancy, primary seed dormancy, postgermination growth, stomatal conductance, abscisic acid catabolism, abscisic acid level, ABA homeostasis, transpiration rate, stomatal development, high humidity response, lateral root emergence, seed germination, ABA metabolism, abscisic acid degradation, seed thermoinhibition, hypo-osmotic response, and drought stress tolerance. The encoded protein localises to the ER membrane and is also associated with extracellular and membrane locations. Related genes in other species link the family to drought tolerance, suppressed transpiration, elevated ABA levels in seeds, and reduced germination without stratification.
