SUNN — Pisum sativum

Summary

PSAT4G142480 (SUNN, also known as PsRLP52) on chromosome 4LG4 encodes a leucine-rich repeat receptor-like kinase with transmembrane receptor serine/threonine kinase activity, ATP binding, and steroid binding. This gene is associated with nodulation, regulation of floral meristem size, floral organ development and specification of floral organ number, plant ovule development, embryo sac development, gametophyte development, and post-embryonic development. It is also linked to cytokinin anabolism, regulation of meristem organisation, stomatal complex morphogenesis and development, response to chitin, detection of brassinosteroid stimulus, regulation of cell growth, heat acclimation, activation of salinity response, and upregulation of response to thirst. The product localises to the membrane and plasmalemma. Related genes in other species link the family to powdery mildew resistance, and sequence similarity connections associate the family with traits including nitrogen content, phosphorus uptake, root length, and sensitivity to acid, nitrate, and abscisic acid.
