Characterization of suppression subtractive hybridization sequences. a Graphical representation of the number of assembled contigs (Y axis) against their length in base pairs. b Distribution of the different groups of sequences classified according to BLAST+ identification (NCBI, May, 2013). We distinguished five different categories: false-positives, which were 100% identical to sequences within the Rm1021 genome; polymorphic sequences, which had different nucleotide sequences but encoded the same protein sequence; orthologous sequences, which displayed >85% identity to S. meliloti 1021 proteins; divergent sequences, corresponding to genes present in the databases but displaying significant identity to sequences from bacteria other than Rm1021; and orphan sequences, not found in the databases.
