ATM4 — Daucus carota subsp. sativus

Summary

DCAR_010775 (DcATM4) on carrot chromosome 3 encodes a protein with sequence-specific DNA binding, DNA binding transcription factor activity, protein dimerization activity, calcium ion binding, BHLH transcription factor binding, and kinase binding. The gene is associated with regulation of flavonoid and proanthocyanidin biosynthesis, glucosinolate biosynthetic and metabolic processes, raffinose metabolism, cellular detoxification of cadmium ions, and response to sulfur starvation. It is linked to root color, root hair localization, trichome morphogenesis and spacing, epidermal cell fate specification, drought recovery, defense response to insects, shoot elongation under submergence, seed protein content, phosphorus uptake, iron concentration, and brassinosteroid content. Related genes in other species link the family to cuticle deposition, suberin synthesis, and drought response, as well as to aliphatic glucosinolate accumulation and insect herbivory resistance.
