Abstract
目的:对由转录组测序获得的伤寒沙门菌(Salmonella enterica serovar Typhi,S.Typhi)非编码小RNA(small non-coding RNA,snRNA) T64的表达进行验证,并对其功能进行初步探讨.方法:选取特异性引物采用反转录PCR(RT-PCR)和普通PCR确认T64在S.Typhi中的表达;将含有T64 snRNA序列的重组质粒导入S.Typhi野生株构建T64高表达株;结合应用S.Typhi全基因组芯片分析技术,比较S.Typhi T64高表达株和空载体对照株在对数期基因表达谱差异,并对部分基因芯片结果进行实时荧光定量PCR(qRT-PCR)验证.结果:RT-PCR结果显示,snRNA T64在S.Typhi确有表达;基因芯片分析结果显示,与空载体对照株比,snRNA T64高表达株在对数期有20个基因表达上调,7个下调;4个被选基因表达的qRT-PCR结果与芯片分析结果相符.结论:snRNA T64在S.Typhi中表达,可能在基因的表达调节中发挥重要作用.
