ATM4 — Daucus carota subsp. sativus

Summary

DCAR_008249 (DcATM4, also known as DcMYB39, DcPMG1, DcPMG2, DcMYB32, DcMYB76, DcMYB74, RAO7, MYB32, MYB76, MYB114, MYB74, MYB39) on carrot chromosome 2 encodes a plant Myb transcription factor containing a Myb DNA-binding domain. The product is a sequence-specific DNA-binding protein with transcription cis-regulatory region binding activity, localised to the nucleus. DcATM4 is associated with the regulation of anthocyanin and lignin anabolism, the shikimate pathway, green leaf volatile biosynthesis, root development, circadian rhythm, and responses to wounding and cold. It is also linked to metaphase, interphase, anaphase, and both up- and down-regulation of DNA-dependent transcription. The gene has been connected to root color. Studies of related genes in other species link the family to phenylpropanoid metabolism and secondary cell wall formation.
