MYB5 — Glycine max

Summary

GmMYB5 (GLYMA_14G154400V4) on soybean chromosome 14 encodes a Myb-family transcription factor with sequence-specific DNA binding and protein dimerization activity. The gene is associated with the regulation of flavonoid, proanthocyanidin, isoflavonoid and phlobaphene biosynthesis, pigment accumulation, vacuolar acidification and transport, citrate secretion, trichome spacing and differentiation, epidermal cell fate specification, and mucilage accumulation during seed coat development. It localizes to the nucleus and root hair. Associations with traits include flower and seed coat color, anthocyanin content, leaf trichome density and morphology, root epidermal cell length, iron concentration, nitrate uptake, brassinosteroid and jasmonic acid content, drought tolerance, biotic and abiotic stress responses, seed development, seed oil content, and heat stress tolerance. Studies of related genes in other species link the family to seed coat development, mucilage, trichome formation, flavonoid and proanthocyanidin biosynthesis, iron accumulation, and root epidermal cell patterning.
