摘　　要：苏云金芽孢杆菌作为应用最为广泛的生物农药,已经成为化学合成农药必要的补充或替代品,其杀虫蛋白基因已成功的应用到转基因抗虫作物中。本文基于海南五指山和吊罗山热带原始雨林区土壤样品筛选分离的Bt菌株资源,利用第二代测序技术Illumina对分离的特异Bt菌株的杀虫基因进行全面分析,鉴定出新型Bt杀虫蛋白基因25个,其中包括5个新型的营养期杀虫蛋白基因(vip)和3个新型cyt基因。本研究表明第二代DNA测序技术可以高效用于挖掘Bt杀虫基因资源,而获得的新型杀虫蛋白基因将进一步丰富我国能够应用的杀虫基因种类。Bacillus thuringiensis（Bt）, as the most widely used biologically produced pest control agent, is already a useful alternative or supplement to synthetic chemical pesticide and is also a key source of genes for transgenic expression to provide pest resistance in plants. On basis of Bt strains isolated from soil samples from the Diaoluoshan and Wuzhishan Natural Reserve, we carried out a large-scale screening the insecticidal genes from the special Bt strains through Illumina sequencing. In this study, 25 of the insecticidal genes, including 5 of the novel vegetative insecticidal protein genes and 3 of the new cyt genes had been identified from the different Bt strains. All the result indicated that the second generation sequencing technology of illumine is efficient in mining the insecticidal gene from Bt isolates, which would further enrich the new different insecticide genes application in commercial agriculture, forest management, and mosquito control.
