IKU2 — Pisum sativum

Summary

PsIKU2 (PSAT1G212240) on chromosome 1LG6 encodes a transmembrane receptor serine/threonine kinase with protein kinase activity, belonging to the plant LRR-RLK family. In garden pea, this gene is associated with endosperm and embryo sac development, floral organ development and specification of floral organ number, regulation of meristem organisation and cell growth, gametophyte and ovule development, stomatal complex morphogenesis, cytokinin anabolism, protein phosphorylation, heat acclimation, and responses to salinity, thirst, and other organisms. It is linked to seed oil content, seed development, and a small seed phenotype. The protein localises to the plasma membrane and extracellular region. Studies of related genes in other species connect the family to seed size, seed mass, endosperm proliferation, and seed volume, shape, weight, and maturation.
