PGIP — Beta vulgaris subsp. vulgaris

Summary

BVRB_4G088310 (PGIP) on sugar beet chromosome 4 encodes a polygalacturonase-inhibiting protein (PGIP) family member with leucine-rich repeat domains. The product exhibits enzyme inhibitor activity, receptor serine/threonine kinase binding, protein serine kinase activity, and ATP binding. It is associated with defense response, signal transduction, heat acclimation, cell differentiation, and regulation of cell growth. The protein localizes to the apoplast, membrane, and plasmalemma. In floral development, it is linked to regulation of floral meristem size, specification of floral organ number, floral organ development, regulation of meristem organization, and gametophyte development. Studies of related genes in other species connect the family to polygalacturonase inhibition and defense responses.
