MYC2 — Daucus carota subsp. sativus

Summary

DCAR_006548 (MYC2, DcBHLH14) on carrot chromosome 2 encodes a protein with domains including AIB/MYC-like, MYC/MYB_N, bHLH-TF_ACT-like_plant, and bHLH_dom, and is annotated with DNA binding, sequence-specific DNA binding, transcription cis-regulatory region binding, and protein dimerization activity. The protein localises to the nucleus and is associated with regulation of jasmonic acid mediated signaling pathway, defense response, positive regulation of anthocyanin anabolism, flavonoid anabolism, trichome morphogenesis, anther dehiscence, dehiscence, pollen development, pollen maturation, regulation of primary metabolic process, regulation of DNA-templated transcription, upregulation of transcription, DNA-dependent transcription, and DNA-dependent transcription. It is linked to photosynthetic rate, drought tolerance, disease resistance, Fusarium wilt resistance, nematode resistance, jasmonate signaling, jasmonate biosynthesis, stress response, and, based on descriptions centred on MYC1, monoterpene and sesquiterpene biosynthesis, trichome initiation, trichome development, trichome formation, herbivore defense, and glandular cell development. Studies of related genes in other species link the family to terpene biosynthesis, steroidal glycoalkaloid biosynthesis, phenylpropanoid-polyamine conjugate biosynthesis, cold tolerance, bacterial leaf spot resistance, and insect resistance.
