摘要: In plants, calcium acts as a universal second messenger in various signal transduction pathways. The plant-specific calcium-dependent protein kinases (CDPKs) play important roles regulating downstream components of signaling. We conducted genome-wide analysis rice CDPKs and identified 29 CDPK genes eight closely related kinase genes, including five CDPK-related (CRKs), one calmodulin-dependent (CCaMK) two phosphoenolpyruvate (PEP) carboxylase kinase-related (PEPRKs). mRNA splicing sites the CDPKs, CRKs PEPRKs (but not OsCCaMK) are highly conserved, suggesting that these derived from common ancestor. RNA gel blot analyses revealed majority exhibited tissue-specific expression. Expression OsCPK9 was elevated seedlings infected by blast, indicating this gene plays an role signaling response to blast treatment. Our genomic bioinformatic will provide foundation for further functional dissection family.
