EXPR — Solanum tuberosum

Summary

StEXPR (PGSC0003DMG400026590) on potato chromosome 6 encodes a protein with expansin domains (Expan_Lol_pI, Expansin_CBD) and a major pollen allergen Ory s 1-like structure, placing it in the expansin-like family. The gene is associated with plant-type cell wall loosening, carbon catabolite repression, catabolite repression, chemotaxis, quorum sensing, proline metabolism, protein processing, sexual reproduction, steroidogenesis, wax anabolism, virus-induced PTGS, systemic acquired resistance, NO storage, morphogenesis, and response to thirst. It is linked to extracellular and membrane localisation. Associations include glucose content, photosynthetic rate, and drought tolerance. Studies of related genes in other species connect the family to stress resistance and fruit development, while sequence similarity links extend to fruit growth, leaf chlorosis, lignin content, auxin content, and salt tolerance.
