DFR — Nicotiana attenuata

Summary

A4A49_64584 (DFR, DFRA) encodes a protein with dihydroflavonol 4-reductase, flavanone 4-reductase, chalcone isomerase, naringenin-chalcone synthase, and flavonol synthase activities, and is associated with flavonol metabolism, chalcone anabolism, regulation of proanthocyanidin anabolism, oxidative phosphorylation, response to gravity, secondary metabolite biosynthesis, histogenesis, flavonol biosynthetic process, autotrophy, proanthocyanidin anabolism, regulation of phenylpropanoid metabolism, pigmentation, regulation of anthocyanin anabolism, response to UV, auxin polar transport, lignin anabolism, secondary metabolism, and anthocyanin anabolism. The gene is linked to traits including UV light sensitivity, stamen morphology, photosynthetic ability, root phototropism, flavonoid content, UV-B light sensitivity, adventitious rootless, herbicide sensitivity, insect damage response, flower development, light intensity response, pollen fertility restoration, photosynthetic rate, stomatal complex closure time, anthocyanin content, low temperature stress response, and oxidative stress response. Localisation evidence connects the product to the cytosol, nucleus, endoplasmic reticulum, tonoplast, and extrinsic to ER membrane. Related genes in other species link the family to anthocyanin biosynthesis, anthocyanin accumulation, glucose content, tuber color, flower color, phenolic compounds content, antioxidant capacity, phenolic antioxidant content, steroid alkaloid
