AT2G22330 — Arabidopsis thaliana

Summary

AT2G22330, known as CYP79B3, encodes a cytochrome P450 enzyme with tryptophan N-monooxygenase activity (EC 1.14.14.156) in Arabidopsis thaliana. This gene is associated with indole glucosinolate metabolism and accumulation, tryptophan breakdown, and IAA biosynthetic processes. CYP79B3 is linked to leaf senescence, non-host resistance to necrotrophic fungi, and pathogen resistance. It is associated with auxin content and biosynthesis, camalexin biosynthesis, and defense responses against aphids, herbivores, and insects. The gene is also associated with plant growth and development traits, including root length, as well as disease tolerance and parasitic plant resistance. Related genes in other species link the family to branch angle. CYP79B3 localizes to membranes and is associated with glucosinolate transport and breakdown, phytoalexin biosynthesis, and secondary metabolite production.
