ATM4 — Beta vulgaris subsp. vulgaris

Summary

BvATM4 (BVRB_8G181400) on sugar beet chromosome 8 encodes a MYB transcription factor with DNA-binding, transcription factor activity, and protein dimerization activity. It is associated with the regulation of flavonoid, anthocyanin, proanthocyanidin, and glucosinolate biosynthesis, as well as raffinose metabolism, cutin anabolism, trichome morphogenesis and spacing, epidermal cell fate specification, defense responses to insects, drought recovery, cellular detoxification of cadmium ions, and response to sulfur starvation. The gene product localizes to the nucleus, cytosol, root hair, preprophase band, and cell cortex. Associations with traits include seed protein content, seed coat morphology, leaf trichome density, root epidermal cell length, shoot elongation under submergence, branch angle, phosphorus response, iron concentration, brassinosteroid content, lignin biosynthesis, and photoperiod-sensitive flowering time. Related genes in other species link the family to cuticle development, suberin biosynthesis, and drought response.
