ARPI — Solanum tuberosum

Summary

PGSC0003DMG400009268, designated ARPI, is a potato gene on chromosome 11 that encodes a serine-type endopeptidase inhibitor belonging to the protease inhibitor I20 family. The encoded protein is localised extracellularly and is associated with defense response, response to wounding, proteolysis, regulation of gene expression, starch anabolism, somatic embryogenesis, secretion, quorum sensing, basophil activation, antibody production, and metabolic burst. ARPI is also linked to amino acid content and photosynthetic rate. Studies of related genes in other species link the family to jasmonic acid content, drought tolerance, chlorophyll content, plant height, root length, leaf number, and germination ratio.
