CYP73 — Cicer arietinum

Summary

CYP73 (C4H) on chickpea chromosome 2 encodes a trans-cinnamate 4-monooxygenase (EC 1.14.14.91), a cytochrome P450 family member. The gene is associated with lignin, flavonoid, pigment, phytoalexin, and ubiquinone metabolism, as well as responses to wounding, light, and cGMP. It has been linked to seed coat color, drought tolerance, UV-B protection, male fertility, plant growth, lignin deposition and content, monolignol biosynthesis, adventitious and lateral root development, auxin transport, Casparian strip formation, and hyperhydricity. The encoded protein localizes to the endoplasmic reticulum, plasma membrane, nucleus, Golgi, plasmodesmata, vacuole, cell wall, and extracellular space. Related genes in other species are linked to cinnamate 4-hydroxylase activity, lignification, abiotic stress adaptation, and dwarfism.
