pgip — Daucus carota subsp. sativus

Summary

DCAR_029654 (pgip) on carrot chromosome 9 encodes a protein with leucine-rich repeat domains, possessing peptide hormone binding, signaling receptor activity, and protein serine/threonine kinase activity, along with calmodulin binding and ubiquitin ligase binding. This gene is associated with defense responses, including activation of defence response to bacteria and upregulation of defense response, as well as brassinosteroid and hormone-mediated signalling, response to nutrient levels, heat acclimation, and specification of floral organ number. The encoded product localizes to the ER membrane, apoplast, plant-type cell wall, and plasmodesma. Associations with disease resistance, immune response, brassinosteroid sensitivity, abscisic acid signaling, root elongation, and shade avoidance response have been noted. Studies of related genes in other species link the family to pathogen resistance, self-incompatibility, and traits including sulfur content and days to flowering.
