PI3K — Cicer arietinum

Summary

LOC101495936 (CaPI3K, also known as CaVPS34) on chickpea chromosome 8 encodes a phosphatidylinositol 3-kinase of the class III/VPS34 type, possessing protein serine/threonine kinase activity and ATP binding. This gene is associated with phosphatidylinositol 3-phosphate biosynthesis, macroautophagy, pexophagy, TOR signaling, endocytosis, and regulation of stomatal closure. It is linked to activation of defence response to bacteria, reactive oxygen species metabolism, and DNA damage checkpoint processes. Associations include leaf senescence, pollen development and germination, root hair growth, proline accumulation, and responses to salt and heat stress. The encoded protein localises to endosome membranes, the Golgi complex, and class III PI3K complexes. Studies of related genes in other species link the family to plant growth and development, disease resistance, and stomatal closure.
