M2 — Solanum tuberosum

Summary

StM2 (M2) on potato chromosome 10 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (PPIase) with annotated cis-trans proline isomerase activity, cyclosporin A binding, salicylic acid binding, peroxidase activity, and L-serine O-acetyltransferase activity. The gene is associated with diverse biological processes including protein proline isomerization, chaperone-mediated protein complex assembly, alternative mRNA splicing, response to light intensity, wound healing, and regulation of ARF protein signal transduction. It has been linked to traits such as variegated leaf, starch grain synthesis, respiration rate, photosynthetic rate, sucrose content, temperature stress response, herbicide sensitivity, root hair length, root mass density, chloroplast development, jasmonic acid content, and plant stress response. Localization evidence connects the product to the Golgi stack, thylakoid lumen, secretory vesicle, and proteasome. Related genes in other species are linked to water stress tolerance, cold stress response, hydrotropism, and phototropism.
