M2 — Solanum tuberosum

Summary

StM2 (PGSC0003DMG400014848) on potato chromosome 8 encodes a cyclophilin-type peptidyl-prolyl cis-trans isomerase (EC 5.2.1.8) with additional annotated molecular functions including salicylic acid binding, peroxidase activity, and histone binding. The gene is associated with diverse biological processes such as protein proline isomerization, alternative mRNA splicing, wound healing, and responses to light intensity and sulfate starvation. StM2 is associated with numerous traits including photosynthetic rate, respiration rate, sucrose content, starch grain synthesis, chloroplast development, root mass density, and responses to temperature stress, zinc, and herbicides. It is also associated with phenotypes such as heat stress tolerance, disease resistance, auxin transport, gravitropism, and root meristem development. Studies of related genes in other species link the family to drought response, cold stress tolerance, hydrotropism, and embryo patterning.
