FIG. 1.

Maximum-likelihood phylogeny of 9,288 bp including 25 isolates across five plant host strains of Xylella fastidiosa using a general time-reversible model with a gamma distribution and invariant sites. Bootstrap values with 200 replicates for the major division are reported above each branch, and Bayesian posterior probabilities are reported below. The PLS isolate was not included in the full maximum-likelihood analysis since only 7 of the 10 genes were sequenced; however, its position in the phylogeny based on the maximum-likelihood analysis using those 7 genes is marked (*).
