PGIP — Beta vulgaris subsp. vulgaris

Summary

BVRB_4G076040 (PGIP) on sugar beet chromosome 4 encodes a leucine-rich repeat-containing N-terminal plant-type domain-containing protein belonging to the PGIP family. The gene 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, regulation of cell growth, cell differentiation, post-embryonic development, and specification of floral organ number. The protein localizes to the apoplast, membrane, and plasmalemma. Related genes in other species, including PGIP1, PGIP2, and HAR1, link the family to defense and developmental signaling, though these associations are not yet established in sugar beet.
