MYB1 — Daucus carota subsp. sativus

Summary

DCAR_010747 (DcMYB90, also known as MYB1 or MYB113) on carrot chromosome 3 encodes a Myb-domain transcription factor with DNA-binding and transcription cis-regulatory region binding activity. The protein localises to the nucleus and is associated with the regulation of primary metabolic process, DNA-templated transcription, and cell differentiation. In carrots, this gene is linked to root-specific anthocyanin pigmentation and anthocyanin biosynthesis. It is associated with positive regulation of anthocyanin anabolism, flavonoid anabolism, pigmentation, and green leaf volatile biosynthetic process. Associations also include anthocyanin content, photosynthetic rate, sesquiterpene accumulation, trichome formation, fruit storage life, resistance to Botrytis cinerea, disease resistance, antioxidant capacity, sugar content, and citric acid content. Studies of related genes in other species link the family to anthocyanin accumulation, petal color, fruit color, drought tolerance, and shelf life.
