RqlH and RqlI homologs are found across various genera, either alone or together.

F11 RqlH and RqlI homologs were found using blastp and tblastn searches of various NCBI sequence databases. (A-E) Distribution of strains containing only a homolog of RqlI (green), only RqlH (red), or both RqlH and RqlI (blue). The numbers of bacterial strains that are associated with each pie section are indicated, with totals given beneath each graph. Included are (A) distributions of RqlH and RqlI orthologs in all strains, (B) among Gram-negative bacteria, (C) among Gram-positive organisms, (D) within the Escherichia genus, or (E) as part of the Streptomyces genus. (F) Examples showing the arrangements of rqlH and rqlI orthologs in different bacterial species.

通过BLASTp与tblastn对NCBI多个序列数据库进行检索，我们成功鉴定到F11菌株的RqlH与RqlI同源序列。(A-E) 三类携带不同同源序列的菌株分布情况：仅携带RqlI同源序列的菌株（绿色）、仅携带RqlH同源序列的菌株（红色），以及同时携带RqlH与RqlI同源序列的菌株（蓝色）。每个饼图切片对应的细菌菌株数量均已标注，各图表下方同时给出了对应类别的总菌株数。本次分析涵盖以下内容：(A) 所有受试菌株中RqlH与RqlI直系同源序列的分布情况；(B) 革兰氏阴性菌中的分布特征；(C) 革兰氏阳性菌中的分布特征；(D) 埃希氏菌属（Escherichia）内的分布情况；以及(E) 链霉菌属（Streptomyces）内的分布情况。(F) 展示不同细菌物种中rqlH与rqlI直系同源序列基因排布模式的示例。
