摘    要:利用BAC-FISH技术,将包含HSP70基因的BAC克隆定位到栉孔扇贝的一对同源染色体的长臂上.HSP70基因的染色体定位将对深入研究该基因的结构及功能并将其应用于生产实践提供基础支持.同时,本研究是首次对栉孔扇贝低拷贝基因进行染色体定位的实践,其结果将为栉孔扇贝的染色体的深入研究以及染色体鉴别等工作提供必要的参考.

关 键 词:栉孔扇贝(Chlamys  farreri)  热休克蛋白70(HSP70)  荧光原位杂交  染色体

Abstract:Zhikong scallop (Chlamys farreri) is one of key species in the marine aquaculture of China. Till present, the disease control is the main issue and many subjects were focused on disease- resistance and stress-related genes. Heat shock protein 70 (HSP70) shows diverse functions in the anti-stress reaction and pathogen-resistance reaction. However, the studies on HSP70 in C. farreri were mainly on a sequence analysis and expression profile, there is no result about the gene localization of HSP70. In this study, with the support of a BAC DNA library of C. farreri, a HSP70-containing BAC clone, CFB123C08, was mapped to the long arms of a pair of homologous chromosomes of C. farreri using BAC-FISH. This study would facilitate further studies on the HSP70 of C. farreri. And as the first attempt of chromosomal mapping of low-copy genes in C. farreri, this study would promote the researches on the chromosome identification of C. farreri.
Keywords:Chlamys farreri  HSP70  BAC-FISH  Chromosome
