CHI2 — Brassica juncea
Summary
BJUA06G31020S (CHI2, also known as BjCHI2, CYP72C1, SOB7, or SHK1) encodes a cytochrome P450 monooxygenase on Indian mustard chromosome A06. The enzyme exhibits brassinosteroid binding, 7-deoxyloganate 7-hydroxylase, secologanin synthase, and monooxygenase activities, and localises to the endoplasmic reticulum membrane. The gene is associated with brassinosteroid inactivation, homeostasis, and metabolism, as well as saponin, indole alkaloid, and cholesterol metabolism. It is linked to plant growth and height, leaf morphology, cell and hypocotyl elongation, photomorphogenesis, flowering time, seed size, male fertility, and response to jasmonic acid and light. Studies of related genes in other species link the family to brassinosteroid catabolism and abiotic stress adaptation.
