PSY — Brassica napus

Summary

BnPSY (DARMORV10_A02P04030.1) on chromosome A02 of oilseed rape encodes a protein with squalene/phytoene synthase domains and squalene synthase, phytoene synthase, dimethylallyltransferase and farnesyltranstransferase activities. The gene is associated with phytoene anabolism, carotenoid anabolism, chromoplast organization, chloroplast organization, de-etiolation, seed development, circadian rhythm, and response to light stimulus. It has been linked to alpha-carotene content, carotenoid content, leaf color, photosynthetic rate, chloroplast development, cell elongation, flowering time, and drought tolerance. Studies of related genes in other species connect the family to carotenoid accumulation, fruit development, flowering time, thermotolerance, seed germination, abscisic acid content, provitamin A carotenoid content, salt stress response, chlorophyll accumulation, and photosynthetic development.
