| Abstract: | The pathogen causing blast disease on Zizania latifolia in Dandong city, Liaoning province is identified as Xenopyricularia zizaniicola by the Koch’s postulate, morphological characteristics, and gene sequences analysis on actin, β-tubulin and calmodulin. A representative pathogenic isolate is similar to X. zizaniicola on conidium morphology and is clustered into one clade with X. zizaniicola in phylogenetic tree. Taken together, our findings indicate that X. zizaniicola is the pathogen of blast disease on Z. latifolia in Dandong city. |
