Assignment of a target sequence to each TRD in Type I specificity (S) genes.

aType I S genes were classified according to orthologous groups [18]. bClassification based on amino acid sequence similarity[18]. cAdenine detected as methylated is underlined. dY, C or T; R, A or G; V, A or C or G; B, C or G or T. eLocus tag of genes that include the TRD. fN/D, methylation motif not detected.a I型S基因（Type I S genes）根据直系同源群（orthologous groups）进行分类[18]。 b 基于氨基酸序列相似性进行分类[18]。 c 被检测到发生甲基化的腺嘌呤会添加下划线标注。 d Y 指代胞嘧啶（Cytosine, C）或胸腺嘧啶（Thymine, T）；R 指代腺嘌呤（Adenine, A）或鸟嘌呤（Guanine, G）；V 指代腺嘌呤（Adenine, A）、胞嘧啶（Cytosine, C）或鸟嘌呤（Guanine, G）；B 指代胞嘧啶（Cytosine, C）、鸟嘌呤（Guanine, G）或胸腺嘧啶（Thymine, T）。 e 包含TRD的基因的基因座标签。 f N/D 代表未检测到甲基化基序。
