Histogram of GC content in proteobacterias genomes that present or lack genes involved in t6A, GluQ, k2C and 2sU modifications. The 1484 proteobacterial genomes were separated in groups depending on the presence or absence of the indicated genes and the GC content of genome sequences was analyzed. Left: Data is represented in superposed histograms. Right: Data is represented in a boxplot. An horizontal bar was added when the two populations are different based on Wilcoxon-Mann-Whitney test and p < 0.00005. Whiskers include 95% of data.

携带或缺失参与t6A、GluQ、k2C及2sU修饰相关基因的变形菌门（Proteobacteria）基因组GC含量直方图。本研究共纳入1484个变形菌门基因组，依据目标基因的有无进行分组，并对各组基因组序列的GC含量进行分析。左图：数据以叠加直方图形式展示；右图：数据以箱线图形式展示。当两组样本经威尔科克森-曼-惠特尼检验（Wilcoxon-Mann-Whitney test）验证存在显著差异（p < 0.00005）时，将添加一条水平横线加以区分。箱线图的须线涵盖95%的观测数据。
