C4H — Brassica oleracea var. botrytis

Summary

BoC4H (BOLND125_C04P064150.1) on cauliflower chromosome 4 encodes a trans-cinnamate 4-monooxygenase, a cytochrome P450 enzyme that binds iron and heme. 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 has been linked to lignin deposition and content, Casparian strip formation, male fertility, plant growth, lateral and adventitious root development, auxin transport, UV-B protection, and hyperhydricity. The encoded protein localises to the endoplasmic reticulum, Golgi, plasmodesmata, plant-type vacuole, plasma membrane, nucleus, and extracellular region. Studies of related genes in other species connect it to lignification, dwarfism, altered phenylpropanoid metabolism, male sterility, and abiotic stress adaptation.
