C4H — Pisum sativum

Summary

PSAT2G050720 (C4H, PsC4H) encodes a cytochrome P450 enzyme with trans-cinnamate 4-monooxygenase activity, located on chromosome 2LG1 of garden pea (Pisum sativum). The gene is associated with lignin metabolism, ubiquinone anabolism, phenylpropanoid anabolism, flavonoid anabolism, JA signaling, developmental process, pollen development, response to wounding, and response to light stimulus. It is linked to wound response, phenylpropanoid biosynthesis, UV-B protection, phenylpropanoid metabolism, male fertility, plant growth, lignin deposition, hyperhydricity, lateral root development, lignin biosynthesis, fertility, lignin production, Casparian strip formation, monolignol biosynthesis, Casparian strip diffusion barrier, adventitious root development, and auxin transport. The protein localizes to the endoplasmic reticulum, plasma membrane, Golgi, plasmodesmata, plant-type cell wall, vacuole, and extracellular space. Studies of related genes in other species connect the family to lignification, dwarfism, altered phenylpropanoid metabolism, male sterility, and abiotic stress adaptation.
