C4H1 (TRAESCS3A02G342900) — triticum aestivum

Summary

TRAESCS3A02G342900, designated C4H1 (synonym CYP73A2) on bread wheat chromosome 3A, encodes a cytochrome P450 73A33 with trans-cinnamate 4-monooxygenase activity (EC 1.14.14.91), heme binding and iron binding. The gene is associated with lignin metabolism and biosynthesis, and with traits including lignin content, grain color, seed coat color, grains per spike, grain number, and grain yield. It is linked to responses to karrikin, nitrate, abiotic and biotic stimuli, as well as to alkaloid metabolism, flavonoid accumulation, calcium transport, proton transmembrane transport, vacuole organization and protein membrane targeting. The product localises to the membrane and nucleus. Related genes in other species link the family to leaf morphology.
