DFR — Nicotiana attenuata

Summary

A4A49_27764 (DFR, DFRA) on chromosome 9 of coyote tobacco (Nicotiana attenuata) encodes a protein with flavanone 4-reductase, dihydroflavanol 4-reductase, chalcone isomerase, naringenin-chalcone synthase and flavonol synthase activities. The gene 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. It is linked to traits including flavonoid content, anthocyanin content, photosynthetic ability, UV light sensitivity, stamen morphology, root phototropism, insect damage response, herbicide sensitivity, low temperature stress response, oxidative stress response, and stomatal complex closure time. Related genes in other species are linked to flavonoid and proanthocyanidin biosynthesis, UV-B sensitivity, oxidative stress tolerance, genome stability, and seed coat pigmentation.
