PGIP — Capsicum annuum

Summary

T459_22761 (PGIP) on pepper chromosome 9 encodes a polygalacturonase inhibitor, a protein with leucine-rich repeat domains that exhibits enzyme inhibitor activity and is annotated with receptor serine/threonine kinase binding and protein kinase activities. The gene is associated with defence responses to fungi, brassinosteroid-mediated signalling, heat acclimation, and regulation of stomatal complex development and cell growth. It is also associated with post-embryonic plant organ development, specification of floral organ number, ovule and embryo sac development, and responses to salinity and thirst. The product localises to the apoplast, membrane and plasmalemma. Related genes in other species link the family to fungal pathogen defence.
