Northern Corn Leaf Blight, caused by Setosphaeria turcica, is one of the important fungous diseases. The pathogenicity of S. turcica to maize is involved in cAMP、MAPK and Ca~(~(2+))signal pathway. Protein kinase C (PKC), a serine/threonine kinases, is depended on phospholip and Ca~(~(2+)). The protein kinase C gene of S. turcica, named as PKC, was cloned and analyzed in our Lab. After inoculating maize seedlings with the spore suspension containing PKC-specific inhibitor (chelerythrine), the spore could ger...
