Application of Research Strategy for Gene Function to Entomopathogenic Fungi

Entomopathogenic fungi are a large group of pathogenic fungi,and include 200 species of host insect in 24 families of 5 orders.Because of effective and environmental friend control on insect pests,the entomopathogenic fungi have been extensively studied.With the coming of post-genomic era,large-scale study of gene function is becoming a hot spot,which has laid a foundation for further clarification for the pathogenic mechanism of pathogenic fungi.So analysis methods of gene function are becoming increasingly sophisticated and diverse.The paper reviews RNA interference,gene knock-out,and bioinformatics analysis,the advantages and disadvantages of the strategies,and their application in the pathogenic fungi.
