CYP79B2 — Brassica oleracea

Summary

BoCYP79B2 (BOLC102_C01P001080.1) on cabbage chromosome 1 encodes a cytochrome P450 protein with tryptophan N-monooxygenase, tyrosine N-hydroxylase, and multiple amino acid N-monooxygenase activities, along with heme and iron binding. This gene is associated with glucosinolate, camalexin, auxin, cyanogenic glycoside, dhurrin, and anthocyanin biosynthesis, as well as tryptophan breakdown, lipid hydroxylation, pollen exine formation, anther development, induced systemic resistance, defense response by callose deposition, and responses to insects and oomycetes. It localizes to the ER membrane and membrane. Phenotypic associations include herbivore, pathogen, aphid, fungal, insect, clubroot, and parasitic plant resistance; disease resistance to Phytophthora brassicae; auxin and indole glucosinolate biosynthesis; plant growth; lateral root development and branching angle; temperature-dependent IAA reduction; zinc oxide nanoparticle tolerance; phenylpropanoid accumulation; and systemic acquired resistance. Studies of related genes in other species link the family to callose deposition, leaf senescence, auxin content, and resistance to Botrytis cinerea.
