M2 — Solanum tuberosum

Summary

StM2 (M2) on potato chromosome 1 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with annotated cis-trans proline isomerase activity, cyclosporin A binding, salicylic acid binding, and peroxidase activity. It is associated with diverse biological processes including protein proline isomerization, regulation of ARF protein signal transduction, alternative mRNA splicing, response to light intensity, wound healing, and cysteine anabolism. The gene has been linked to traits such as variegated leaf, starch grain synthesis, respiration rate, photosynthetic rate, sucrose content, root hair length, chloroplast development, jasmonic acid content, and responses to temperature stress, zinc, and herbicides. Studies of related genes in other species connect the family to heat stress tolerance, pre-mRNA splicing, hydrotropism, phototropism, cold stress tolerance, and embryo patterning.
