Fig.4From: Diversity of pathogenic Pseudomonas isolated from citrus in TunisiaPhylogenetic tree of representative strains of the P. syringae group isolated in this study from citrus plants with symptoms. Concatenated 16S rRNA, gyrB and rpoD gene partial sequences were used and reference strains of the P. syringae phylogenetic group were included in the analysis. Distance matrices were calculated by the Jukes-Cantor method (Jukes and Cantor 1969). The tree was generated by the neighbour-joining method. P. aeruginosa ATCC 10145 T was used as the outgroup. The bar indicates sequence divergence. Percentage bootstrap values of more than 50% (from 1000 replicates) are indicated at the nodesBack to article page
