C4H — Brassica oleracea

Summary

BoC4H (BOLC102_C03P020970.1) on cabbage chromosome 3 encodes a cytochrome P450 family protein with trans-cinnamate 4-monooxygenase activity, iron and heme binding, and identical protein binding. The gene is associated with phenylpropanoid, flavonoid, anthocyanin, glucosinolate, lignin, ubiquinone, and secondary metabolite biosynthesis, as well as anthocyanin and chlorophyll breakdown, pigmentation, leaf and pollen development, wound and light responses, and developmental processes. It localises to the endoplasmic reticulum, Golgi, plasmalemma, nucleus, plant-type cell wall, vacuole, plasmodesmata, and extracellular regions. The gene is linked to flavonoid, anthocyanin, and sugar content, drought tolerance, lignin deposition and content, male fertility, plant growth, lateral and adventitious root development, Casparian strip formation, auxin transport, hyperhydricity, and UV-B protection. Studies of related genes in other species connect the family to lignification, dwarfism, altered phenylpropanoid metabolism, male sterility, and abiotic stress adaptation.
