C4H — Brassica napus

Summary

BnC4H (DARMORV10_A04P23220.1) on chromosome A04 of oilseed rape encodes a cytochrome P450 family protein with trans-cinnamate 4-monooxygenase activity, iron and heme binding, and protein binding capabilities. The gene is associated with phenylpropanoid, lignin, anthocyanin, proanthocyanidin, pectin, cellulose, hormone, and ubiquinone metabolism, as well as pigment accumulation, leaf formation, developmental processes, and protein modification. It has been linked to plant height, stem diameter, seed and leaf color, anthocyanin content, wound response, UV-B protection, male fertility, lignin deposition, Casparian strip formation, lateral and adventitious root development, auxin transport, and hyperhydricity. The protein localizes to the endoplasmic reticulum, Golgi, plasma membrane, nucleus, vacuole, plasmodesmata, and cell wall. Related genes in other species are associated with lignification, dwarfism, altered phenylpropanoid metabolism, and abiotic stress adaptation.
