ATM4 — Daucus carota subsp. sativus

Summary

DCAR_003717, also known as DcATM4, encodes a protein with a Myb DNA-binding domain and SANT/Myb domain, and has sequence-specific DNA binding and transcription factor activity. The gene is associated with pigment accumulation, including anthocyanin, flavonoid, and phlobaphene biosynthetic processes, as well as positive regulation of anthocyanin metabolism. It has been linked to root color, lignin regulation, green leaf volatile biosynthesis, and defense responses to insects. Additional associations include cell differentiation, root development, and stress responses. The protein localizes to the nucleus. Related genes in other species, such as sorghum y1, link the family to anthocyanin regulation, though these functions are not established for DcATM4 itself.
