SUNN — Pisum sativum

Summary

PSAT1G047640 (SUNN, also known as PsRLP52) on garden pea chromosome 1LG6 encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeat domains, belonging to the LRR-receptor-like kinase family. It exhibits kinase activity, ATP binding, steroid binding, and SNARE binding, and is localized to the plasma membrane and endosomes. The gene is associated with regulation of floral meristem size and organ number, floral organ development, gametophyte development, plant ovule development, stomatal complex morphogenesis, response to chitin, detection of brassinosteroid stimulus, cytokinin anabolism, microtubule bundling, heat acclimation, and activation of salinity response. Related genes in other species link the family to powdery mildew resistance, and sequence similarity connections associate the family with traits including nitrogen content, root length, and phosphorus uptake.
