1. P-network of 2,616 prokaryote genomes based on chromosomal sequences with rRNA genes removed.
P-network of 2,616 prokaryote genomes based on chromosomal sequences with rRNA genes removed. The network was generated using D2S with k = 25 at t = 3; only nonsingleton nodes are shown. Each edge between two nodes represents the number of connections between isolates from the two phyla; the thickness of each edge is proportional to the number of genome pairs with shared k-mers. The size of each node is proportional to the number of isolates within the phylum. Singletons are not shown. The five representative Proteobacteria groups are labeled with the corresponding Greek characters. The highway of k-mer sharing between Betaproteobacteria and Gammaproteobacteria is indicated in red.
