CYP79B2 — Arabidopsis thaliana
Summary
AT4G39950 (CYP79B2) in Arabidopsis thaliana encodes a cytochrome P450 enzyme with tryptophan N-monooxygenase activity (EC 1.14.14.156), catalyzing the conversion of L-tryptophan to indole-3-acetaldoxime. This gene is associated with indole glucosinolate biosynthesis and content, auxin biosynthesis, and camalexin production. CYP79B2 has been linked to resistance against Botrytis cinerea, necrotrophic fungi, aphids, insects, and clubroot, as well as to callose deposition, leaf senescence, and phenylpropanoid content. It is also connected to plant growth and development traits, including root length and branch angle, and to responses such as systemic indole accumulation and temperature-dependent reduction in free IAA levels. The gene product localizes to the membrane and is associated with IAA biosynthesis, glucosinolate transport, and response to lipopolysaccharide. Studies of related genes in other species link the family to early senescence, reduced size, and lower auxin levels.
