MYB1 — Beta vulgaris subsp. vulgaris
Summary
BvMYB1 (BVRB_2G023500) on sugar beet chromosome 2 encodes a MYB transcription factor with RNA polymerase II-specific DNA-binding and chromatin-binding activities. This gene is associated with positive regulation of anthocyanin and lignin biosynthesis, pigmentation, secondary metabolism, anther and tapetum development, syngamy, embryogenesis, pollen development, and green leaf volatile production. It is linked to responses to auxin, cold, salinity, and thirst, as well as cell differentiation and transcriptional regulation. BvMYB1 has been connected to root shape, petiole length, salt tolerance, and drought tolerance. The protein localizes to the nucleus, nuclear speck, and cytosol. Studies of related genes in other species link the family to osmotic and salt stress tolerance, abscisic acid response, leaf shape, seed germination under salt stress, and tapetum development, while tomato studies connect it to leaf development.
