鳜鱼传染性脾肾坏死病毒基因组文库和物理图谱的建立

A gene library of the infectious spleen and kidney necrosis virus(ISKNV) from mandarinfish,Siniperca chuatsi(Basilewsky) genome was established ISKNV DNA was cleaved with EcoRI,BamHI,HindⅢ,KpnI and PstI and the resulting fragments were inserted into the corresponding sites of the pBluescript Ⅱ KS plasmid vector using T4 DNA ligase Bacterial colonies harboring recombinant plasmids were selected All cloned fragments were individually identified by digestion of the recombinant plasmid DNA with different restriction enzymes and screened by hybridization of recombinant plasmid DNA to viral DNA Using these recombinant plasmids,the physical maps of the genome were constructed for BamHI,HindⅢ and KpnI restriction endonucleases
