PME21 — Capsicum annuum

Summary

CaPME21 (PME21, T459_33702) on pepper chromosome PGAv.1.6.scaffold1273 encodes a pectinesterase with pectinesterase inhibitor activity (EC 3.1.1.11), containing pectinesterase catalytic and inhibitor domains. The gene is associated with pectin breakdown, cell wall modification, fruit ripening, and pollen development, and its product localises to the apoplast. It has also been linked to inositol phosphate metabolism, oxidative phosphorylation, phosphate metabolism, and cytoplasmic male sterility. Studies of related genes in other species connect the family to root morphology traits, though this has not been established in pepper.
