Taxonomic Distribution of LGT Donors and Distribution of KEGG Annotations of LGT Candidates
LGT donors are shown in (A), and KEGG annotations of LGT candidates in (B). The numbers of LGT candidates in each KEGG category are shown in (B). See also Table S1.

4. Figure 2 Cellular Processes Affected by LGT in Blastocystis ST1
(A) Overview of the main cellular processes affected by LGT. Proteins are color coded depending on the process they are involved in. Those labeled with several colors are involved in multiple processes. Not all LGT candidates are depicted.
(B–E) Close-ups of LGT affecting carbohydrate uptake and metabolism (B), immune response evasion and pathogenicity (C), nitrogen metabolism (D), and anaerobic energy metabolism (E).

5. Figure 3 Maximum-Likelihood Phylogeny of NAD Synthase
Shades of gray highlight bacterial, archaeal, and viral homologs. Other colors represent eukaryotic homologs. GenBank accession numbers and annotation are provided next to each taxon. Numbers in brackets indicate the number of homologs collapsed. Numbers at branches are UltraFast bootstrap support (BS); only values ≥70 are indicated. Blastocystis sp. ST1 homologs are bolded. The branch leading to Pleisiocystis pacifica was reduced to two-thirds of its original length (double dashes). The Coptotermes formosanus sequence is marked with an asterisk to indicate that it is most likely a contaminating sequence from a parabasalid gut symbiont.

6. Figure 4 Maximum-Likelihood Phylogeny of Serine Dehydratase
The legend from Figure 3 applies unless otherwise specified hereafter. The tree was arbitrarily rooted based on functional domain composition, as displayed on the right end of the figure: the ingroup sequences are predicted to be composed of a split serine dehydratase alpha chain (teal) and a serine dehydratase beta chain (purple), whereas the outgroup sequences are predicted to be composed of a single alpha chain domain followed by a beta chain longer than in the ingroup.

9. Figure 7
Differential Presence of Genes of LGT Origin in Blastocystis STs
Only STs for which complete (bolded) or draft genome data are available are represented. Colored and crossed-out circles on branches represent LGT events and gene losses, respectively. Only laterally acquired genes detected in ST1 and seemingly absent in one or more other subtypes are represented. Additional cases of genes acquired at the base of the lineage and subsequently lost in individual STs have been detected but have not been reported because the genome data for ST2, ST3, ST6, ST8, and ST9 are still incomplete.
