ATR4 — Brassica oleracea

Summary

BoATR4 (BOLC102_C08P010620.1) on cabbage chromosome 8 encodes a cytochrome P450 monooxygenase with heme and iron binding, oxidoreductase activity acting on paired donors with NAD(P)H, and gibberellin binding. The gene is associated with glucosinolate and indole glucosinolate biosynthesis, auxin (IAA) biosynthesis and homeostasis, tryptophan formation, coumarin biosynthesis, and raffinose family oligosaccharide biosynthesis. It is linked to floral organ morphogenesis, shade avoidance, adventitious root development, defense response via callose deposition, induced systemic resistance, and gibberellin-mediated signaling. Associations with agronomic traits include plant height, stem length and elongation, flowering time, stamen length, fruit and seed growth and development, sulfur content, gibberellic acid sensitivity, and pollen fertility restoration. The protein localises to the ER membrane, cytoplasm, nucleus, mitochondria, and plasma membrane.
