FL — Medicago truncatula

Summary

MTR_5G059140, designated FL and also known as MtFLS, encodes a protein with a DIOX_N domain and an Oxoglu/Fe-dep_dioxygenase_dom, and is annotated with flavonol synthase, leucocyanidin oxygenase, flavanone 3-dioxygenase, flavanone 4-reductase, dihydroflavanol 4-reductase and naringenin-chalcone synthase activities. The gene is associated with flavonol, anthocyanin, proanthocyanidin and coumarin biosynthesis, as well as the regulation of phenylpropanoid and anthocyanin metabolism. It is linked to responses to UV-B light, jasmonic acid, auxin, oxidative stress, wounding, fungal molecules, gravity and light, and to nodulation and innate immunity. Associations with traits include anthocyanin content, seed coat pigmentation, pollen fertility, flower development, root morphology, stomatal closure, and tolerance to drought, salt, low temperature, nitrogen stress, herbicides, heavy metals and photooxidation. Studies of related genes in other species connect the family to root gravitropic response, cyst nematode resistance and circadian rhythm.
