Relative expression ratios of <i>suxR, suxC, suxA</i> and <i>suxB</i> in the wild-type strain, in minimal medium containing 20 mM sucrose <i>vs</i> minimal medium without sucrose.

aFrom real-time quantitative reverse-transcriptase polymerase chain reaction perfomed in at least three independent experiments. Cells were cultivated in minimal medium with or without sucrose. Calculation of relative expression includes normalization against the 16S rRNA endogenous control gene. SD: standard deviation.本数据集的实验数据来源于至少三次独立重复实验中开展的实时定量逆转录聚合酶链反应（real-time quantitative reverse-transcriptase polymerase chain reaction）。实验细胞在添加或不添加蔗糖的基础培养基中进行培养。相对表达量的计算以16S rRNA内源对照基因为参照实施标准化处理。SD：标准差（standard deviation）。
