A likely horizontally transferred gene in Entodinium. The tree contains the target sequence (AM054010) and its homologuous proteins. To determine whether the target sequence is HGT candidate, an algorithm examines the presence or absence of Bacteria, Archaea and Eukaryotes in the second smaller partition containing the target sequence. In the example, the smallest second partition containing the target sequence contains also the sequences from Bacillus halodurans, Xanthomonas axonopodis, Xanthomonas campestris and Thermotoga maritima, which are all Bacteria. AM054010 was therefore retained as a HGT candidate.
