MYB1 — Daucus carota subsp. sativus

Summary

DCAR_010746, also known as DcMYB90, MYB1 or MYB113 on carrot chromosome 3, encodes a Myb-domain transcription factor that localises to the nucleus and binds sequence-specific DNA. The gene is directly associated with positive regulation of anthocyanin biosynthesis and anabolism, flavonoid anabolism, pigmentation, and root-specific anthocyanin pigmentation in carrots. It is also linked to regulation of lignin anabolism, primary metabolic processes, cell differentiation, and both upregulation and downregulation of transcription. Associations extend to traits including anthocyanin content, photosynthetic rate, sesquiterpene accumulation, trichome formation, fruit storage life, sugar and citric acid content, antioxidant capacity, and resistance to Botrytis cinerea. Studies of related genes in other species connect the family to petal and fruit color, drought tolerance, disease tolerance, heterosis, and chlorophyll content.
