MYB1 — Beta vulgaris subsp. vulgaris

Summary

BvMYB1 (BVRB_2G024590) on sugar beet chromosome 2 encodes a MYB transcription factor with RNA polymerase II-specific DNA-binding and chromatin-binding activities. This nuclear-localised protein is associated with the regulation of phenylpropanoid metabolism, pigmentation, anthocyanin anabolism, and green leaf volatile biosynthetic process. It is linked to anther development, anther wall tapetum development, pollen development, cell differentiation, circadian rhythm, and responses to auxin and cold. BvMYB1 is associated with salt tolerance, drought tolerance, and transcriptional regulation. Studies of related genes in other species associate the family with osmotic stress tolerance, salt stress tolerance, abscisic acid response, leaf development, and tapetum development. Sequence similarity connections further link the family to traits including sugar content, anthocyanin content, root shape, grain size, fruit shape, and stomatal resistance.
