Relationship among type III secretion effector repertoires. Neighbor Joining split network based on binary representations of the type III effector repertoires found in the 23 hrp-positive Xanthomonas genomes compared in this study. The network visualizes all conflicting and incompatible bipartitions (“splits”) encountered during a bootstrap resampling with 1000 replicates, and each split is colour-coded according to its bootstrap support as indicated in the legend. The split-lengths were calculated using the Hamming distance and represent the number of effector flips (from absent to present or reverse) between each point in the network. Distances greater than 1 were indicated on splits with more than 40% bootstrap support. The network visualizes 94 out of 543 calculated splits or 88.1% of the total split weight, and is supported by a global cophenetic correlation of 82%.
