PME — Solanum tuberosum

Summary

StPME (PGSC0003DMG400019199) on potato chromosome 10 encodes a pectinesterase with pectinesterase and pectinesterase inhibitor activities (EC 3.1.1.11), placing it in the pectinesterase catalytic domain family. The gene is associated with pectin metabolism and breakdown, cell wall modification and thickening, wound healing, fruit ripening, cell cycle and division, signal transduction, detoxification, lipid and wax metabolism, memory, and response to thirst. It has been linked to traits including amylose content, heterosis, lignin content, stem elongation, and photosynthetic rate. Related genes in other species connect the family to fruit firmness, fruit color, fruit weight and size, sugar and protein content, lycopene and chlorophyll content, cellulose content, root length, turgor pressure, and cytoplasmic male sterility.
