SUNN — Pisum sativum

Summary

PSAT6G144560 (SUNN) on garden pea chromosome 6LG2 encodes a transmembrane receptor serine/threonine kinase with an extracellular leucine-rich repeat domain, possessing transmembrane receptor protein serine/threonine kinase activity and ATP binding. The gene is associated with regulation of floral meristem size, floral organ development and specification of floral organ number, as well as phloem or xylem histogenesis, gametophyte development, embryo sac development, and plant ovule development. It has been linked to cytokinin anabolism, stimulus detection, regulation of meristem organisation, stomatal complex morphogenesis, heat acclimation, and response to other organisms. Localisation evidence links the product to the plasma membrane and extracellular region. Studies of related genes in other species connect the family to regulation of meristem size and nodulation control.
