PME — Solanum tuberosum

Summary

StPME (PGSC0003DMG400042971) on potato chromosome 10 encodes a pectinesterase with pectinesterase and pectinesterase inhibitor activities (EC 3.1.1.11). The protein contains a pectinesterase catalytic domain and a pectin lyase fold. This gene is associated with pectin metabolism and breakdown, cell wall modification and thickening, wound healing, fruit ripening, cell cycle, and cell division. It has also been linked to amylose content, heterosis, lignin content, stem elongation, and photosynthetic rate. Studies of related genes in other species connect the family to fruit firmness, fruit color, fruit weight and size, sugar content, lycopene content, cellulose content, chlorophyll content, root length, turgor pressure, and cytoplasmic male sterility.
