M2 — Daucus carota subsp. sativus

Summary

DCAR_025710 (DcM2) on carrot chromosome 7 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase with tetratricopeptide repeat domains, and is annotated with cis-trans proline isomerase activity, cyclosporin A binding, salicylic acid binding, peroxidase activity, and is associated with protein proline isomerization, chaperone-mediated protein complex assembly, and alternative mRNA splicing. The gene is associated with numerous traits including variegated leaf, starch grain synthesis, respiration rate, temperature stress response, zinc sensitivity, phototropism response, root phototropism response, sucrose content, meristem tissue development, herbicide sensitivity, inflorescence morphology, cotyledon morphology, root hair length, light intensity response, root mass density, cell cycle, chloroplast development, jasmonic acid content, arsenic concentration, photosynthetic rate, embryo development, stomatal closure, leaf composition, seedling growth, and organ identity. It is also linked to heat stress tolerance, pre-mRNA splicing, pathogen defense, boron transport, root hydrotropism, disease resistance, apical hook development, embryo patterning, lateral root initiation, gravitropism, auxin transport, and membrane trafficking. Studies of related genes in other species connect the family to water stress tolerance, cold stress, hydrotropism, phototropism, embryo patterning, drought response, and chromium tolerance.
