SUNN — Pisum sativum

Summary

PSAT7G240520 (SUNN) on chromosome 7LG7 of garden pea encodes a transmembrane receptor protein serine/threonine kinase, belonging to the Ser/Thr kinase diverse regulatory family. The gene is associated with nodulation, regulation of floral meristem size, floral organ development, specification of floral organ number, cytokinin anabolism, gametophyte development, embryo sac and plant ovule development, post-embryonic development, stomatal complex morphogenesis and its regulation, regulation of cell growth, heat acclimation, response to other organisms, activation of salinity response, and upregulation of response to thirst. The encoded protein localises to the plasma membrane and extracellular region. Studies of related genes in other species link the family to similar developmental and symbiotic processes.
