Length distribution of strain genomes and pan-genome contigs. a Distribution of the number of sequenced strains across microbial species in GenBank. Left panel, the proportion of species that have different numbers of sequenced strains. Right panel, the proportion of strains that have different numbers of sequenced conspecific strains. b The length distribution of pan-genome contigs in panDB. Left panel, the proportion of short (less than 1000 bp) and long (greater than 1000 bp) contigs in the microbial pan-genome sequences. Right panel, the proportion of bases that are found within the short or long contigs
