M2 — Daucus carota subsp. sativus

Summary

DcM2 (DCAR_025117) on carrot chromosome 7 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with cyclosporin A binding, peroxidase activity, and additional annotated molecular functions including salicylic acid binding, histone binding, and U5/U2 snRNA binding. The gene is associated with protein proline isomerization, chaperone-mediated protein complex assembly, alternative mRNA splicing, and responses to light intensity, sulfate starvation, arsenic, and chlorate. It is linked to numerous traits including photosynthetic rate, respiration rate, sucrose content, starch grain synthesis, root mass density, root hair length, herbicide sensitivity, zinc sensitivity, temperature stress response, and variegated leaf. Associations also extend to chloroplast development, meristem identity, embryo development, inflorescence morphology, and jasmonic acid content. Related genes in other species are linked to heat stress tolerance, cold stress tolerance, drought response, hydrotropism, phototropism, embryo patterning, and resistance to Botrytis cinerea.
