ATM4 — Daucus carota subsp. sativus

Summary

DCAR_028146 (DcATM4) on carrot chromosome 8 encodes a protein with MYB transcription factor domains and is associated with DNA binding, transcription factor activity, and protein dimerization. It is associated with regulation of flavonoid and proanthocyanidin biosynthesis, glucosinolate metabolism, trichome morphogenesis and spacing, epidermal cell fate specification, defense response to insects, cellular detoxification of cadmium ions, response to sulfur starvation, and drought recovery. The gene has been linked to traits including root color, leaf trichome density, seed protein content, adventitious root number, phosphorus uptake, iron concentration, lignin biosynthesis, and photoperiod-sensitive flowering. Related genes in other species connect the family to cuticle deposition, suberin synthesis, drought response, glucosinolate accumulation, and insect herbivory resistance.
