PGIP — Beta vulgaris subsp. vulgaris

Summary

BVRB_4G088330, designated PGIP, encodes a polygalacturonase-inhibiting protein (PGIP) family member on sugar beet chromosome 4. The product contains leucine-rich repeat domains and is annotated with enzyme inhibitor activity, receptor serine/threonine kinase binding, transmembrane receptor protein serine/threonine kinase activity, and protein serine kinase activity, as well as ATP binding. The protein localises to the apoplast, membrane and plasmalemma. PGIP is associated with defence response, signal transduction, cell differentiation, heat acclimation, and regulation of cell growth. It is associated with stomatal complex morphogenesis and its regulation, specification of floral organ number, plant ovule development, embryo sac development, and responses to thirst and salinity. Related genes in other species link the PGIP family to receptor kinase signalling and developmental regulation.
