pgip — Daucus carota subsp. sativus

Summary

DCAR_017029 (pgip) on carrot chromosome 5 encodes a leucine-rich repeat-containing N-terminal plant-type domain-containing protein with enzyme inhibitor activity, transmembrane receptor protein serine/threonine kinase activity, and ATP binding. The gene is associated with defense response, heat acclimation, regulation of cell growth, specification of floral organ number, plant ovule development, embryo sac development, stomatal complex morphogenesis and its regulation, upregulation of response to thirst, and activation of salinity response. The product localizes to the apoplast, membrane, and plasmalemma. Studies of related genes in other species, including PGIP1, PGIP2, and CLV1A, connect the family to polygalacturonase-inhibiting protein function and receptor kinase signaling.
