FIG 2.

Phylogeny of crown gall-associated Xanthomonas strains isolated in this study based on the concatenated sequences of four housekeeping genes, i.e., atpD, efp, gyrB, and rpoD, using tree-based maximum-likelihood (A) and network-based NeighborNet (B) analyses. The five Xanthomonas strains isolated from weeping fig and Amaranthus sp. were divided into two clades, where the weeping fig strains were closely related to but still distinct from the X. translucens species complex. The Amaranthus sp. strain was distinct from all the validly described species with clade I of Xanthomonas. Further, parallel lines/branches within the nodes of the NeighborNet network indicate possible recombination between the connected strains.
