Supplement to "Lifestyle-associated variation in type IV secretion systems between phytopathogenic and environmental Ralstonia"

Supplemental Table S1 lists details of the RSSC phytopathogen, non-RSSC environmental, and Burkholderiaceae family genomes used in this study. Supplemental Table S2A is the final list of 503 VirB4 sequences collectively identified in 644 RSSC phytopathogen genomes and 143 non-RSSC environmental genomes. Supplemental Table S2B includes the annotations and NCBI accessions for every gene and protein sequence in reference clusters a-p. Supplemental Table S2C is the list of putative T4SS cargo genes identified in complete Ralstonia genomes. Supplemental Table S2D is the list of putative T4SS cargo genes identified in cluster i regions from draft and complete Ralstonia genomes.

Supplemental File S1 is the multiple sequence alignment (MSA) input for HMMER, made from the 753 VirB4 protein sequences from the Burkholderiaceae family genomes. Supplemental Files S2 and S3 are the species trees displaying the presence of T4SS gene clusters in RSSC phytopathogens and non-RSSC environmentals, respectively. Supplemental File S4 is the species tree displaying the presence of RSp0179 and RSp1521 in the Ralstonia genus. Supplemental File S5 is the MSA input for FastTree 2, made from the VirB4 protein sequences from Ralstonia genomes. Supplemental Files S6-S9 are various formats of the VirB4 protein tree in Figure 1. Supplemental Files S10-S25 are the GBK files for reference clusters a-p. Supplemental File S26 is the clinker output comparing the reference clusters. Supplemental Files S27-S36 are the clinker outputs comparing the putative regions of transfer of T4SSs in complete Ralstonia genomes. Supplemental File S37 is the clustered ANI matrix for the putative regions of transfer of cluster i T4SSs in draft and complete Ralstonia genomes. Supplemental File S38 is the clinker output comparing the cluster i regions in draft and complete Ralstonia genomes.

This study’s newly sequenced genomes, Gazipur 4 and Gazipur 5, are available on NCBI with the following accessions: GCF_049860735.1 and GCF_049860725.1, respectively. The two contigs containing the cluster j T4SS were submitted to NCBI through the Third Party Annotation (TPA) section of the DDBJ/ENA/GenBank databases with the following accessions: BK072068-BK072069. These contigs were assembled from SRA reads under the accession: SRR18649448.
