M2 — Daucus carota subsp. sativus

Summary

DCAR_030974 (DcM2) on carrot chromosome 9 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with cyclosporin A binding, salicylic acid binding, and peroxidase activity, and is annotated for diverse molecular functions including histone and chromatin binding, U2/U5 snRNA binding, and L-serine O-acetyltransferase activity. The gene is associated with numerous biological processes such as protein proline isomerization, alternative mRNA splicing, response to light intensity, arsenic, and chlorate, as well as endosome transport, planar polarity establishment, and embryonic pattern specification. DcM2 is linked to traits including variegated leaf, starch grain synthesis, respiration rate, sucrose content, root hair length, root mass density, photosynthetic rate, jasmonic acid content, and responses to temperature stress, zinc, and herbicides. It is also associated with phenotypes such as heat stress tolerance, disease resistance, auxin transport, gravitropism, root meristem development, and embryo patterning. Related genes in other species link the cyclophilin family to water stress tolerance, pathogen defense, cold stress response, hydrotropism, and apical-basal patterning.
