JAM3 — Daucus carota subsp. sativus

Summary

DcJAM3 (DCAR_000434) encodes a transcription factor with DNA-binding and protein-dimerization activity, belonging to the bHLH and MYC-like families. It is associated with the regulation of anthocyanin and flavonoid biosynthesis, pigmentation, and jasmonic acid-mediated signaling pathways. The gene has been linked to responses to low humidity, basic pH, and defense responses, including systemic acquired resistance. DcJAM3 is also associated with guard cell fate commitment, trichome morphogenesis, and cell differentiation. In terms of traits, it has been associated with insect damage response, vegetative growth time, jasmonic acid content, root thickness, flowering time, and disease tolerance. Related genes in other species link the family to stomatal development, pathogen resistance, and freezing tolerance. The protein localizes to the nucleus and is involved in hormone signaling pathways, particularly those mediated by jasmonic acid.
