SUNN — Pisum sativum

Summary

PSAT7G145320 (SUNN) on chromosome 7LG7 of garden pea encodes a transmembrane receptor protein serine/threonine kinase with protein kinase activity and ATP binding, belonging to the LRRC69/RLP family with leucine-rich repeat domains. The gene is associated with cytokinin anabolism, post-embryonic plant organ development, regulation of floral meristem size and floral organ number, gametophyte development, megasporogenesis, microsporogenesis, anther wall tapetum development, plant ovule development, stomatal complex morphogenesis, and regulation of cell growth. It is also linked to activation of defense responses to bacteria, upregulation of defense response, and responses to salinity and thirst. The encoded protein localises to the membrane, plasmalemma, ER membrane, extracellular region, and nucleus. Studies of related genes in other species link the family to additional roles in meristem regulation and disease resistance.
