Table 2. Natural habitats of extant prokaryotes harboring the closest orthologs to Cyanidiales HGTs.
Numbers in brackets represent how many times HGT candidates from Cyanidiales shared monophyly with non-eukaryotic organisms; for example Proteobacteria were found in 53/96 of the OG monophylies. Kingdom: Taxon at kingdom level. Species: Scientific species name. Habitat: habitat description of the original sampling site. pH: pH of the original sampling site. Temp: Temperature in Celsius of the sampling site. Salt: Ion concentration of the original sampling site. na: no information available.
