CPK13 — Zea mays

Summary

ZM00001EB072810, designated CPK13 on maize chromosome 2, encodes a protein with calcium/calmodulin-dependent serine/threonine kinase activity, calcium ion binding, calmodulin binding, and ATP binding, and belongs to the CDPK_Ser/Thr_kinases family with EF-hand domains. This gene is associated with biological processes including intracellular signaling, immune memory response, regulation of root hair elongation, tube development, cell cycle DNA replication, nitrogen fixation, seed growth, sucrose anabolism, and responses to stimuli such as actidione and chewing. It is linked to membrane, cytosol, plasmalemma, cytoplasm, and nucleus localization. CPK13 is associated with traits including grain yield, grain weight, ear weight, seed size, seed longevity, seed viability, seedling vigor, root hair length, root length, chlorophyll content, stomatal resistance, water use efficiency, and tolerances to drought, salt, heat, and cold. Related genes in other species support these associations.
