SAPK8 — Sorghum bicolor

Summary

SORBI_3001G078800, designated SAPK8, encodes a non-specific serine/threonine protein kinase (EC 2.7.11.1) with protein serine/threonine kinase activity and ATP binding. In sorghum, SAPK8 is associated with abscisic acid (ABA) signaling, seed germination, seedling development, protein autophosphorylation, and protein phosphorylation. It localizes to the cytosol, cytoplasm, and nucleus. The gene is linked to drought tolerance and responses to drought and salinity, as well as ABA biosynthesis and mediated signaling. Studies of related genes in other species connect the SAPK8 family to proline content, germination rate, and salt tolerance.
