Characterization of the bacterium Pantoea vagans identified in Zea mays and Solanum tuberosum samples. a Taxonomic tree of reads from Solanum tuberosum and Zea mays assigned to different taxonomic levels. The size of the circle represents the amount of reads assigned to the node displayed in the tree or to any taxonomic level below it. S. tuberosum- and Z. mays-derived reads are shown in green and orange, respectively. b Cytosine to Thymine substitutions at the 5′ end of P. vagans for U-selected libraries (U-enriched and U-depleted fractions) from Z. mays and S. tuberosum. c Principal component analysis of P. vagans from Z. mays and S. tuberosum samples, as well as nine publicly available genomes, based on single nucleotide polymorphisms. Numbers in axis labels indicate the percentage of the variance explained by each principal component (PC)
