RD (TRAESCS3A02G226600) — triticum aestivum

Summary

TRAESCS3A02G226600 (TaRD, also known as TaDFR-3A, TaTT3-3A, or TaM318-3A) on bread wheat chromosome 3A encodes a protein with NAD(P)-binding and epimerase/dehydratase domains that exhibits dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, naringenin-chalcone synthase, and chalcone isomerase activities. The gene is associated with anthocyanin, flavonoid, and chalcone biosynthesis, as well as responses to UV-B, oxidative stress, jasmonic acid, auxin, wounding, and light stimulus. TaRD is associated with grain number, grain size, spikelet number, heading time, flag leaf area, leaf width, photosynthetic ability, and seed coat color. It is also linked to low nitrogen stress tolerance and to root development traits including root number, root length, and root gravitropic response.
