C4H — Brassica oleracea var. botrytis

Summary

BoC4H, the C4H gene on chromosome 3 of cauliflower (Brassica oleracea var. botrytis), encodes a cytochrome P450 enzyme with trans-cinnamate 4-monooxygenase activity, heme and iron binding, and belongs to the Cyt_P450 family. This gene is associated with phenylpropanoid and lignin biosynthesis and metabolism, secondary growth, ubiquinone anabolism, macroautophagy, programmed cell death, innate immunity, wound response, and response to light stimulus. It is linked to lignin deposition and content, Casparian strip formation, male fertility, plant growth, lateral and adventitious root development, auxin transport, and UV-B protection. The encoded protein localizes to the endoplasmic reticulum, plasmalemma, nucleus, Golgi, plant-type vacuole, cell wall, and plasmodesmata. Related genes in other species are linked to lignification, dwarfism, altered phenylpropanoid metabolism, and abiotic stress adaptation.
