CPK9 (TRAESCS4A02G283400) — triticum aestivum

Summary

TRAESCS4A02G283400, symbol CPK9 and also known as TaCDPK1-5A, encodes a non-specific serine/threonine protein kinase with EF-hand calcium-binding domains, calmodulin-binding capacity, and ATP-binding activity. This bread wheat gene on chromosome 4A is associated with pollen maturation, inhibition of the salinity response, response to karrikin and nitrate, vacuole organization, protein membrane targeting, positive regulation of flavonoid anabolism, regulation of the hypersensitive response, intracellular signal transduction, osmotic response, and cellular homeostasis. It is linked to calcium concentration and drought tolerance, and its product localizes to the membrane, plasmalemma, cytoplasm, and nucleus. The gene is connected to pathways including regulation of seed germination and coleoptile growth under submergence, gravitropism, and responses to abiotic stimuli. Studies of related genes in other species link this gene family to calcium signaling and stress responses.
