PGIP — Beta vulgaris subsp. vulgaris

Summary

BVRB_4G088340 (PGIP) on sugar beet chromosome 4 encodes a protein with PGIP and leucine-rich repeat domains and annotated enzyme inhibitor activity, transmembrane receptor protein kinase activity, and protein serine/threonine kinase activity. The gene is associated with defense response, response to other organisms, signal transduction, and protein phosphorylation. It has been linked to developmental processes including specification of floral organ number, plant ovule development, embryo sac development, stomatal complex morphogenesis, and regulation of cell growth. Associations with stress responses include heat acclimation, activation of salinity response, and upregulation of response to thirst. The encoded product localizes to the apoplast, extracellular region, membrane, and plasmalemma. Studies of related genes in other species link the family to polygalacturonase inhibition and defense against fungal pathogens.
