MYB1 — Daucus carota subsp. sativus

Summary

DCAR_028796, designated DcMYB1 (also known as MYB1, MYB44, SRM1, DcMYB25, and DcMYB44) on carrot chromosome 8, encodes a DNA-binding transcription factor with transcription cis-regulatory region binding activity. The protein localizes to the nucleus, nuclear speck, and cytosol. In carrot, DcMYB1 is associated with anthocyanin biosynthesis, pollen development, and stress response. It is linked to anthocyanin content, drought tolerance, and salt tolerance. Related genes in other species are associated with osmotic stress tolerance, abscisic acid response, tapetum development, leaf development, and seed germination under salt stress. Distant sequence similarity also links the family to traits such as root shape, grain size, fruit shape, sugar content, and stomatal resistance.
