EXPA6 — Solanum tuberosum

Summary

PGSC0003DMG400016715, the potato gene EXPA6 on chromosome 2, encodes an expansin protein characterized by expansin and RlpA-like domains. The encoded product is associated with plant-type cell wall loosening and organization, cell wall biogenesis, meristem development, and diverse metabolic processes including auxin, sucrose, lipid, carbohydrate, secondary, and isoflavonoid metabolism, as well as wax biosynthesis, protein modification, detoxification, and nitric oxide storage. The protein is localized to the extracellular region and membrane. Related genes in other species link the expansin family to cell wall modification and growth regulation, though these associations are not yet established for this potato gene.
