ATM4 — Daucus carota subsp. sativus

Summary

DCAR_012982 (DcATM4) on carrot chromosome 4 encodes a protein with a Myb DNA-binding domain, SANT/Myb domain and homeobox-like superfamily domain. The product exhibits sequence-specific DNA binding, transcription cis-regulatory region binding, chromatin binding, protein dimerization activity, calcium ion binding, protein kinase activity and BHLH transcription factor binding. DcATM4 is associated with regulation of flavonoid and proanthocyanidin anabolism, glucosinolate biosynthetic process, raffinose metabolic process, trichome morphogenesis and spacing, defense response to insects, cellular detoxification of cadmium ion, response to sulfur starvation, and plant epidermal cell fate specification. It localises to the nucleus, cytosol, root hair, preprophase band, cell cortex and TGN. The gene is linked to root color, leaf trichome density, seed protein content, anthocyanin pigmentation, glucosinolate biosynthesis, drought stress tolerance, salt stress tolerance, thermotolerance, insect herbivory resistance, root-system architecture, iron homeostasis, and shoot elongation under submergence.
