M2 — Solanum tuberosum

Summary

StM2 (PGSC0003DMG400006200) on potato chromosome 1 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with annotated activities including cyclosporin A binding, salicylic acid binding, peroxidase activity, and GTP:GDP antiporter activity. The gene is associated with diverse biological processes such as protein proline isomerization, regulation of ARF protein signal transduction, alternative mRNA splicing, wound healing, and responses to light intensity, chlorate, and sulfate starvation. It has been linked to traits including variegated leaf, starch grain synthesis, respiration and photosynthetic rates, sucrose content, root hair length, meristem development, chloroplast development, jasmonic acid content, and stress responses to temperature, zinc, and herbicides. Studies of related genes in other species connect the family to water stress tolerance, hydrotropism, phototropism, cold stress tolerance, and embryo patterning, as well as seed methionine content and storage protein accumulation.
