ATM4 — Daucus carota subsp. sativus

Summary

DCAR_008094 (DcATM4) on carrot chromosome 2 encodes a protein with a Myb domain and SANT/Myb domain, and is associated with DNA binding, transcription factor activity, protein dimerization activity, chromatin binding, kinase binding, and calcium ion binding. In carrot, DcATM4 is linked to regulation of proanthocyanidin and flavonoid biosynthesis, raffinose metabolism, glucosinolate biosynthesis, trichome morphogenesis and spacing, epidermal cell fate specification, defense response to insects, cadmium detoxification, sulfur starvation response, and drought recovery. It localizes to the nucleus, cytosol, root hair, and preprophase band. Associations with related genes MYC1 and MYC4 are noted. Related genes in other species are linked to glucosinolate accumulation, cuticle and suberin deposition, trichome differentiation, root epidermal patterning, and responses to drought, salt, ammonium, and cadmium stress.
