PS3 — Zea mays
Summary
ZM00001EB376640, designated PS3 (also known as ZmSRPK5, ZmG3PP2, and MPK1), encodes a protein with MAP kinase and serine/threonine kinase domains on maize chromosome 9. The product has been annotated with MAPKK activity, protein tyrosine kinase activity, and glucose 6-phosphate:phosphate antiporter activity. PS3 is associated with biological processes including embryonic meristem development, ear development, microsporocyte differentiation, pre-harvest sprouting, lignin metabolism, and salicylic acid metabolism. It localizes to the spliceosome complex, nuclear speck, and endomembrane system. The gene is linked to traits such as grain width, plant vigor, inflorescence size, relative biomass, net photosynthetic rate, water use efficiency, salinity tolerance, and high temperature stress response. Studies of related genes in other species connect the family to phosphate homeostasis, stem cell maintenance, and organ development.
