NOTE.—The proteins associated with the genes were selected based on having a BH with Bacteria or Archaea, followed by a phylogenetic analysis using the 250 BHs in the complete nonredundant database supplemented with the ten BHs in Eukaryotes and requiring a highly supported clustering of the N. ovalis gene with noneukaryotic genes, see Materials and Methods for details. With each HGT candidate are indicated the genus name of the species with the BH, the National Center for Biotechnology Information-identifier of the best hit, the source of the genetic material for the N. ovalis gene (cDNA or gDNA), and the extra evidence that the sequence is indeed derived from N. ovalis (the presence of telomeres specific for N. ovalis genes or of a poly A tail for a cDNA). Y indicates the presence of an ortholog of the mitochondrial protein in the corresponding species, N its absence. A blank cell is inserted if no answer is possible due to the incomplete genome. Species with mitochondria: (Hsa) Homo sapiens, (Sce) Saccharomyces cerevisiae, (Tth) Tetrahymena thermophila, (Pte) Paramecium tetraurelia, (Ram) Reclinomonas americana, and (Pfa) Plasmodium falciparum; species with hydrogenosomes: (Tva) Trichomonas vaginalis, (Bla) Blastocystis, (Pla) Psalteriomonas lanterna, and (Psp) Piromyces sp.; and species with a mitosomes: (Cpa) Cryptosporidium parvum, (Ehi) Entamoeba histolytica, (Gla) Giardia lamblia, and (Ecu) Encephalitozoon cuniculi.
