SUNN — Pisum sativum

Summary

PSAT3G051680, also known as SUNN, encodes a non-specific serine/threonine protein kinase with transmembrane receptor protein kinase activity, belonging to the plant receptor-like kinase family with leucine-rich repeat domains. In garden pea, this gene is associated with the regulation of floral meristem size, floral organ development and specification of floral organ number, as well as phloem or xylem histogenesis, gametophyte development, and stomatal complex morphogenesis. It is also linked to cytokinin anabolism, heat acclimation, response to other organisms, and activation of salinity response. The encoded protein localises to the plasma membrane and extracellular region. Studies of related genes in other species connect this family to additional roles in meristem regulation and nodulation control.
