ATM4 — Daucus carota subsp. sativus

Summary

DCAR_004151, also known as DcATM4, encodes a protein with a Myb DNA-binding domain and SANT/Myb domain on carrot chromosome 1. The protein localises to the nucleus and exhibits sequence-specific DNA binding, chromatin binding, transcription cis-regulatory region binding, DNA binding, and DNA binding transcription factor activity. This gene is associated with metaphase, interphase, anaphase, the shikimate pathway, regulation of lignin anabolism, green leaf volatile biosynthetic process, anther wall tapetum development, anthocyanin anabolism, circadian rhythm, regulation of gene expression, downregulation of transcription, response to wounding, root development, DNA-dependent transcription, and regulation of DNA-templated transcription. It has also been connected to root color traits. Studies of related genes in other species, such as MYB42, MYB31, and MYB80, link the family to similar regulatory processes, though these functions are not yet established for DcATM4 itself.
