CYP734A6 (TRAESCS2D02G157300) — triticum aestivum

Summary

TRAESCS2D02G157300 (symbol CYP734A6) on bread wheat chromosome 2D encodes a cytochrome P450 monooxygenase with secologanin synthase activity, heme and iron binding, and oxidoreductase activity acting on paired donors with oxygen incorporation. The gene is associated with brassinosteroid metabolism, miRNA transcription, regulation of enzyme activity, reactive oxygen species anabolism, proline metabolism, the ascorbate-glutathione cycle, oxidative phosphorylation, sulfur metabolism, and secondary metabolite biosynthesis including indole alkaloids, isoflavonoids, and saponins. It localizes to the ER membrane and membrane. Associations with agronomic traits include culm and ear color, awn color and length, flag leaf angle, grain shattering, seed shape, grain texture and width, starch quality, coleoptile length, canopy temperature, leaf necrosis, stem rust, heading time, days to maturity, biomass yield, shoot and root dry weight, zinc and iron concentration, and nitrate transport. Studies of related genes in other species link the family to spikelet number.
