Population heterogeneity of Nomuraea atypicola, a causal pathogen in spider populations
引起蜘蛛流行病的紫色野村菌种群异质性

The genetic diversity of Nomuraea atypicola,a causal pathogen of spider epizootic in Langyashan Nature Reserve and Guniujiang Nature Reserve,was investigated using the technique of inter-simple sequence repeat (ISSR).DNA bands (117) were amplified with 9 selected ISSR primers,111 of which showed polymorphism.A hirerarchical dendrogram constructed with the UPGMA method revealed a high differentiation among 22 tested isolates,with a Jaccard similarity coefficient at 0.48-0.88,an average at 0.71.The 22 isolate...
