摘要: 采用代表性差异分析方法,以小菜蛾的敏感品系作为驱赶扩增子,抗杀螟丹近等基因系作为检测扩增子,通过轮消减杂交得到大小为150~00bp的差异片段,经亚克隆测序并与GenBank等数据库同源比较,发现其中一个亚克隆序列与P450基因有部分同源性,其余亚克隆与已知基因序列的同源性较低,判断这些序列可能是新基因的片段.

关键词: 小菜蛾, 杀螟丹, 代表性差异分析法

Abstract: The genomic difference between Plutella xylostella L.susceptible strain and cartap resistance near isogenic line strain was preliminarily analyzed by representationaLdifference analysis ( RDA)technique.In RDA system, the driver amplicon is susceptible strain while the tester amplicon is cartap resistance near isogenic line strain.After three rounds of subtractive hybridization, the different products were obtained and their sizes were about 150-300 bp.Comparisons between our sub-clone sequencing results and GenBank show that only one sub-clone sequence has P450 gene homology, other sub-clone sequences show no homology to knew gene.Preliminary judgment revealed that these segments might be new gene sequences.

Key words: :Diamondback moth, Plutella xylostella L , Cartap, Representational difference analysis( RDA)
