SUNN — Pisum sativum

Summary

PSAT6G062600 (SUNN) on chromosome 6LG2 encodes a transmembrane receptor protein serine/threonine kinase with ATP binding activity, belonging to the plant LRR-RLK family. The gene is associated with nodulation, regulation of floral meristem size, floral organ development, and specification of floral organ number. It has been linked to cytokinin anabolism, regulation of meristem organisation, gametophyte development, embryo sac development, plant ovule development, and post-embryonic development. Associations also include stomatal complex morphogenesis and its regulation, regulation of cell growth, heat acclimation, response to other organisms, protein phosphorylation, and upregulation of response to thirst and activation of salinity response. The product localises to the plasma membrane, membrane, and extracellular region. Related genes in other species link the family to regulation of meristem size and nodulation control.
