C4H — Brassica juncea

Summary

BJUB06G39980S (BjC4H) encodes a cytochrome P450 enzyme with trans-cinnamate 4-monooxygenase activity, also annotated for iron and heme binding. This Indian mustard gene on chromosome B06 is associated with lignin metabolism, phenylpropanoid metabolism and anthocyanin, flavonoid and ubiquinone anabolism. It is linked to leaf formation, pigmentation, pollen development, wound response, light response and nitric oxide storage. Associations include seed and leaf color, anthocyanin content, lignin deposition and content, male fertility, plant growth, lateral and adventitious root development, auxin transport, Casparian strip formation and hyperhydricity. The protein localises to the endoplasmic reticulum, plasmodesmata, Golgi, vacuole, plasma membrane, nucleus, cell wall and extracellular space. Studies of related genes in other species connect it to lignification, dwarfism, altered phenylpropanoid metabolism, male sterility and abiotic stress adaptation.
