FIG 2.

Dual-probe cross-hybridization network visualized with Cytoscape (v2.8.3). Nodes of the network represent the probes designed to target each genus in the RDP database. Nodes are colored by their phylogenetic group and sized according to their number of potential cross-hybridizations with other genera. Edges represent cross-hybridizations with a high risk of causing a false-positive identification (Δ[FA]_m,SRM of more than −10%). Labeled genera have more than 5,000 sequences in the RDP database (version 10.28).
