MYB1 — Daucus carota subsp. sativus

Summary

DCAR_000385 (DcMYB90, also known as MYB1, MYB113, or MYB113-like) on carrot chromosome DCARv2_C10735702 encodes a plant MYB transcription factor containing a Myb DNA-binding domain and a SANT/Myb domain. As a sequence-specific DNA-binding transcription factor, it is associated with the positive regulation of anthocyanin biosynthesis and anabolism, flavonoid anabolism, pigmentation, and regulation of lignin anabolism. The gene has been connected to root-specific anthocyanin pigmentation and purple pigmentation in carrots. It is also linked to photosynthetic rate, anthocyanin content, sesquiterpene accumulation, trichome formation, fruit storage life, resistance to Botrytis cinerea, disease resistance, antioxidant capacity, sugar content, and citric acid content. The protein localizes to the nucleus and is associated with regulation of primary metabolic processes, cell differentiation, and both upregulation and downregulation of DNA-dependent transcription.
