In this study,we focus on the interaction between nuclear modifier gene MTO2 and aminoglycosides,and have received the following innovations.1,We here report first that the knockout of MTO2 significantly inhibited mtDNA p_(454)~R mutant's sensitivity to aminoglycoside antibiotics.Here are the results:(1)In neomycin GYP medium,when mitochondria genes were wild type,whether MTO2 knockout or not,the growth of yeast strains has no significant difference;when mitochondria genes were complete deletion,whether MTO2 knockout or not,the growth of yeast strains also has no significant difference;Interesting,when mtDNA P_(454)~R,wild-type MTO2 strains were hardly survival in neomycin GYP medium,but the growth of MTO2 knockout strains were only partly inhibited,there was a significant difference performance of neomycin sensitivity between them.

具体结果如下：(1)在含有新霉素的葡萄糖培养基上，mtDNA为野生型、MTO2敲除与否，相应的酵母菌株的生长没有显著差异；mtDNA完全缺失、MTO2敲除与否，相应的酵母菌株的生长也没有显著差异；然而，当mtDNA存在P_(454)~R突变时，MTO2野生型菌株几乎完全不能生长，而MTO2敲除菌株的生长只受到部分抑制，表现二者对新霉素的敏感性存在显著差异。

The protocol for the detections of all the AIV isolates, the H5-subtype and the optimization of reactions were studied with a H5-subtype reference isolate BSG1. A 229bp-band of AIV specific and a 380bp-band of H5 subtype specific were amplified individually with the designed primers of AIV specific and H5-subtype specific respectively by the developed RT-PCR technique from isolate BSG1. A double-PCR was also developed which can detect all the AIVs and identify the H5-subtype AIVs. The results of specificity experiment showed that there was no specific band could be amplified with the samples of Newcastle disease virus, infectious bronchitis virus, infectious laryngotracheitis virus, egg drop syndrome virus and infectious bursal disease virus.
