BAS1 — Pisum sativum

Summary

PsBAS1 (PSAT6G145680) on chromosome 6LG2 of garden pea encodes a cytochrome P450 monooxygenase of the CYP734A family, with steroid hydroxylase, secologanin synthase and monooxygenase activities, and is localised to the ER membrane. The gene is associated with brassinosteroid metabolism, homeostasis and response, as well as seed growth, development and germination, saponin and cholesterol metabolism, and responses to jasmonic acid and light stimulus. It has been linked to starch and protein content, and to phenotypes including brassinosteroid catabolism and inactivation, photomorphogenesis, flowering time, hypocotyl elongation, organ boundary formation, oxidative stress tolerance, and plant growth. Studies of related genes in other species connect the family to brassinosteroid content and sensitivity, light response, germination rate, organ identity, and flowering time traits.
