FLS — Glycine max

Summary

GmFLS (GLYMA_06G110600V4) encodes a flavonol synthase, a 2-oxoglutarate-dependent dioxygenase with oxidoreductase activity that also exhibits leucocyanidin oxygenase, flavanone 3-dioxygenase, and dihydroflavanol 4-reductase activities. In soybean, this gene is associated with flavonoid, anthocyanin, isoflavonoid, and coumarin biosynthesis, as well as auxin polar transport, response to gravity, UV-B, oxidative stress, and fungal elicitors. It has been linked to traits including flower and seed color, phenolic compound content, photosynthetic ability, root length, salt and low-temperature stress tolerance, herbicide sensitivity, and heterosis. Phenotypic associations include seed coat pigmentation, proanthocyanidin accumulation, drought tolerance, root-knot nematode resistance, and stamen development. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species connect the family to root gravitropic response, cyst nematode resistance, male fertility, and circadian rhythm.
