MYB1 — Daucus carota subsp. sativus

Summary

DcMYB1 (DCAR_024045) on carrot chromosome 7 encodes a MYB transcription factor with RNA polymerase II-specific DNA-binding and chromatin-binding activities. It is associated with the regulation of anthocyanin and lignin anabolism, anther development, anther wall tapetum development, pollen development, and cell differentiation. The gene is linked to stress response, cold response, wounding response, drought tolerance, salt tolerance, and activation of salinity and thirst responses. DcMYB1 localises to the nucleus, nuclear speck, and cytosol. Studies of related genes in other species connect the family to osmotic stress tolerance, salt stress tolerance, abscisic acid response, seed germination under salt stress, leaf development, and tapetum development, while sequence similarity links extend to traits such as root shape, grain size, fruit shape, sugar content, and stomatal resistance.
