Phylogenetic insights derived from six Xanthomonas draft genome sequences associated with bacterial spot disease of tomato and pepper in Turkey

<i>Xanthomonas</i> spp. are increasingly recognized as a global threat to agriculture, impacting a broad range of economically important crops. We report the whole-genome sequences of six <i>Xanthomonas</i> strains isolated from tomato and pepper plants in Turkey that were experiencing symptoms of bacterial spot disease. Phylogenomic analysis with representative <i>Xanthomonas</i> genomes from each species revealed that three of these strains belonged to <i>Xanthomonas perforans</i>, two to <i>Xanthomonas euvesicatoria</i> and one to <i>Xanthomonas campestris</i>. We then analysed the phylogenomic relatedness of these strains with other strains from these respective species and characterized their type III secreted effector content. These genomic data represent a valuable resource for understanding the genetic diversity and local epidemiology of bacterial spot disease in Turkey.
