pgip — Daucus carota subsp. sativus

Summary

DCAR_013563 (symbol pgip) on carrot chromosome 4 encodes a PGIP family member, characterised by leucine-rich repeat domains and annotated with enzyme inhibitor activity, transmembrane receptor protein serine/threonine kinase activity, and ATP binding. The gene is associated with defence response, response to other organisms, and protein phosphorylation. It is linked to specification of floral organ number, plant ovule development, embryo sac development, stomatal complex morphogenesis, and regulation of cell growth. Associations with heat acclimation, activation of salinity response, and upregulation of response to thirst connect pgip to abiotic stress responses. The encoded protein localises to the apoplast, extracellular region, and membrane. Related genes in other species, including PGIP1-3 and FOR1, link the family to defence signalling and receptor kinase functions.
