C4H — Daucus carota subsp. sativus

Summary

DCAR_018641 (symbol C4H, also known as DcC4H, DcCYP73A5, DcCYP73A16, CYP73A5, CYP73A16, DcREF3) on carrot chromosome 5 encodes a cytochrome P450 enzyme with trans-cinnamate 4-monooxygenase activity, iron and heme binding, and identical protein binding. This gene is associated with lignin content, metabolism, and anabolism; phenylpropanoid, anthocyanin, and ubiquinone anabolism; response to wounding and light stimulus; pollen development; and carbohydrate metabolism. It is linked to lignin deposition, monolignol and phenylpropanoid biosynthesis, male fertility, plant growth, Casparian strip formation, auxin transport, lateral and adventitious root development, UV-B protection, and hyperhydricity. The encoded protein localizes to the endoplasmic reticulum, plant-type cell wall, vacuole, Golgi, plasmodesmata, plasma membrane, nucleus, and extracellular regions. Studies of related genes in other species link the family to lignification, dwarfism, altered phenylpropanoid metabolism, male sterility, and abiotic stress adaptation.
