FLS — triticum aestivum

Summary

TRAESCS6D02G310700 (FLS) on wheat chromosome 6D encodes a flavonol synthase, a 2-oxoglutarate-dependent dioxygenase with leucocyanidin oxygenase, flavanone 3-dioxygenase and dihydroflavanol 4-reductase activities. The gene is associated with flavonol and anthocyanin biosynthesis, chalcone and coumarin anabolism, and regulation of phenylpropanoid metabolism. It is linked to responses to UV-B, jasmonic acid, auxin, wounding, oxidative stress, gravity, and molecules of fungal origin, as well as seed germination and auxin polar transport. Associations with agronomic traits include grain color, plant height, stripe rust resistance, powdery mildew resistance, drought and salt stress tolerance, photosynthetic ability, root morphology, and herbicide sensitivity. The protein localises to the cytosol, nucleus, endoplasmic reticulum and tonoplast. Studies of related genes in other species link the family to root gravitropism, flavonol synthesis, male fertility and seed coat pigmentation.
