PSY — Brassica juncea

Summary

BJUB08G54390S (symbol PSY) on chromosome B08 of Indian mustard (Brassica juncea) encodes a protein with squalene/phytoene synthase domains and is annotated with squalene synthase, phytoene synthase (PSase), and farnesyltranstransferase activities. This gene is associated with carotenoid and chlorophyll anabolism, pigment metabolism, autotrophy, detoxification, the TCA cycle, and seed germination. Its product localizes to the chromoplast stroma, chloroplast membrane, and plastoglobule. Associations also link PSY to flavonoid content, chlorophyll content, and stomatal opening. Studies of related genes in other species connect the family to EC 2.5.1.32 (phytoene synthase).
