PGIP — Beta vulgaris subsp. vulgaris

Summary

BVRB_3G060740 (PGIP) on sugar beet chromosome 3 encodes a protein with leucine-rich repeat domains and enzyme inhibitor activity, also annotated with receptor serine/threonine kinase binding, transmembrane receptor protein serine/threonine kinase activity, and protein serine kinase activity. The gene is associated with defense responses, including detection of symbiotic fungi, activation of defense response to bacteria, positive regulation of the hypersensitive response, and upregulation of defense response. It is also linked to innate immunity, signal transduction, heat acclimation, specification of floral organ number, regulation of cell growth, and cell differentiation. The encoded protein localizes to the plasma membrane, external side of the plasma membrane, apoplast, endoplasmic reticulum membrane, perinuclear ER membrane, cortical ER, and nucleus. Studies of related genes in other species link the family to further defense-related functions.
