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野生型菌几乎完全不能生长,而MTO2敲除菌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.
