Host-adaptation in Legionellales is 2.4 Gya, coincident with eukaryogenesis

This dataset contains genomes, proteomes and protein alignments mentioned in Hugoson et al (2021). It has been used to analyze the evolution of host-adaptation in the order Legionellales. The data is organized by dataset type, and then by dataset. The four datasets used here are <strong>Gamma105</strong>, comprising 105 <em>Gammaproteobacteria</em> and 5 outgroups; <strong>Legio93</strong>, comprising 93 <em>Legionellales</em> and 20 outgroups; <strong>Gamma66</strong>, derived from Gamma105 by removing <em>Legionella</em>, <em>Francisella</em>, <em>Fangia</em> and <em>Piscirickettsia</em> genera; <strong>Bacteria72</strong>, comprising 49 Gammaproteobacteria and 23 outgroups. <strong>1_genomes</strong><br> Genomes as downloaded or assembled 1_1_Gamma105 1_2_Legio93 1_3_Gamma66 1_4_Bacteria72 <strong>2_proteomes</strong><br> Proteomes, as annotated by prokka 2_1_Gamma105 2_2_Legio93 2_3_Gamma66 2_4_Bacteria72 <strong>3_alignments</strong> In the first three folders, the following files are found. All sequence and alignment files are in fasta format: *_concatenated.fasta: concatenated alignment, trimmed. *.map: map of the files, tab-separated. The first row is a title row. The three first columns give the organism, the marker and the id (as found in the fasta file) for the protein. *_unaligned: non-aligned sequences for each marker. *_aligned: aligned sequences, for each marker. The prefix gives the software used for the alignment. *_trimmed: aligned, trimmed sequences for each marker. The prefix gives the software used to trim the alignment. <strong>3_1_Gamma105</strong>: Based on the Bact109 set of marker, used in Figure 5 and Supplementary Figures 2, 7 and 12 <strong>3_2_Legio93</strong>: Based on the Bact109 set of marker, used in Figure 1 and Supplementary Figures 1, 2 and 11 <strong>3_3_TB4SS_auto</strong>: Alignment of 12 genes of the T4BSS, automatically detected in all genomes. Used for the tree in Supplementary Figure 5. <strong>3_4_TB4SS_manual</strong>: Alignment of 25 genes of the T4BSS, manually curated by collinearity analysis. Used for the tree in Supplementary Figure 6. <strong>3_5_Gamma66</strong>: Based on the Bact109 set of marker, used for the tree in Supplementary Figure 9. <strong>3_6_Bacteria72</strong>: Based on the Bact109 set of marker, used for the tree in Supplementary Figure 10.
