21KD — Solanum tuberosum

Summary

PGSC0003DMG400010809, also known as St21KD or StPMEI11, encodes a 21kD protein containing a pectinesterase inhibitor domain and is annotated with pectinesterase inhibitor activity and pectinesterase activity. This potato gene on chromosome 3 is associated with cell wall modification, cell adhesion, plant-type cell wall organization, pectin breakdown, and defense response. It has been linked to wax anabolism, lipid metabolism, detoxification, signal transduction, shade avoidance, regeneration, memory, and response to thirst. The protein localizes to the apoplast, plant-type cell wall, plastid, and extracellular regions. St21KD is associated with root yield, photosynthetic rate, drought tolerance, and immunity to Botrytis cinerea. Related genes in other species are linked to cell wall development and Botrytis immunity.
