MYC2 — Daucus carota subsp. sativus

Summary

DCAR_010770, the carrot MYC2 gene on chromosome 3, encodes a basic helix-loop-helix (bHLH) transcription regulator with sequence-specific DNA binding, transcription cis-regulatory region binding, and protein dimerization activity. This nuclear-localized gene is associated with jasmonic acid (JA) signaling, positive regulation of anthocyanin anabolism, and flavonoid anabolism. It is linked to pollen maturation, pollen development, anther dehiscence, dehiscence, trichome morphogenesis, regulation of primary metabolic process, DNA-templated transcription, and upregulation of transcription. Related genes in other species link the family to additional aspects of anthocyanin regulation and stress responses, though these associations are not yet established in carrot.
