M2 — Daucus carota subsp. sativus

Summary

DCAR_024828 (DcM2) on carrot chromosome 7 encodes a protein with a cyclophilin-type peptidyl-prolyl cis-trans isomerase domain and a cyclophilin-like domain, and is annotated with cyclosporin A binding and peroxidase activity. The gene is associated with diverse biological processes including protein proline isomerization, chaperone-mediated protein complex assembly, alternative mRNA splicing, and responses to light intensity, sulfate starvation, and arsenic. DcM2 is linked to traits including photosynthetic rate, respiration rate, sucrose content, root mass density, root hair length, chloroplast development, jasmonic acid content, and stress responses including temperature and herbicide sensitivity. It is also associated with phenotypes including heat stress tolerance, disease resistance, root hydrotropism, gravitropism, auxin transport, and embryo patterning. Related genes in other species link the family to cold stress tolerance, drought response, and phototropism.
