| xylella taiwanensis sp. nov., causing pear leaf scorch disease. | a gram-stain-negative, nutritionally fastidious bacterium (pls229t) causing pear leaf scorch was identified in taiwan and previously grouped into xylella fastidiosa. yet, significant variations between pls229t and xylellafastidiosa were noted. in this study, pls229t was evaluated phenotypically and genotypically against representative strains of xylellafastidiosa, including strains of the currently known subspecies of xylellafastidiosa, xylella fastidiosa subsp. multiplex and 'xylella fastidiosa ... | 2016 | 27530392 |
| genome-wide comparison and taxonomic relatedness of multiple xylella fastidiosa strains reveal the occurrence of three subspecies and a new xylella species. | a total of 21 xylella fastidiosa strains were assessed by comparing their genomes to infer their taxonomic relationships. the whole-genome-based average nucleotide identity and tetranucleotide frequency correlation coefficient analyses were performed. in addition, a consensus tree based on comparisons of 956 core gene families, and a genome-wide phylogenetic tree and a neighbor-net network were constructed with 820,088 nucleotides (i.e., approximately 30-33 % of the entire x. fastidiosa genome). ... | 2016 | 27209415 |
