From: Novel groups and unique distribution of phage phoH genes in paddy waters in northeast China
Neighbour-joining phylogenetic tree of phoH amino acid sequences obtained in this study with reference phoH sequences of cultured phages of autotrophs and heterotrophs, viruses of eukaryotic autotrophs, and cultured autotrophic and heterotrophic bacterial hosts.
Clones in this study were named to reflect the sampling site, biomarker gene name and clone number. In detail, DA, SH, MDJ and YJG indicated samples from Daan (green words in bold), Suihua (pink words in bold), Mudanjiang (red words in bold) and Yanjiagang (blue words in bold), respectively. The green, pink and blue triangles indicate phoH clusters obtained from Daan, Suihua and Yanjiagang, respectively, and the grey triangles represent phoH clusters obtained from more than one paddy sample. The phoH sequences of isolated virus and phage origins are in bold black font, and their clusters are indicated with black triangles. The phoH sequences of isolated host origins are in normal black font, and their clusters are indicated with white triangles. Bootstrap values <50 are not shown. The scale bar represents the abundance of amino acid substitutions per residue.
