[…] ome sequences of P. wasabiae strains WPP163 () and SCC3193 (, ), isolated from infected potato tubers in the United States and Europe, respectively, and the type strain P. wasabiae CFBP3394, isolated from horseradish in Japan, are available at GenBank (, ). The draft genome sequence data for P. wasabiae strain CFIA1002 were generated using paired-end Illumina HiSeq sequencing technology with TruSeq version 3 chemistry at the National Research Council Canada (Saskatoon, Saskatchewan, Canada). Sequencing resulted in 8,682,640 reads (insert size, 300 bp) totaling 876,946,640 bp, each 101 bp in length. The sequencing data provided approximately 175× genome coverage. After quality checking using FastQC (http://www.bioinformatics.babraham.ac.uk/projects/fastqc/), initial de novo assembly using ABySS () produced 78 contigs contained in 69 scaffolds, of which scaffolds with lengths of <300 bp were removed. SSPACE () and GapFiller () were applied on the scaffolds to extend and merge them into larger scaffolds and to close the gaps between the short scaffolds. The final draft genome is 5,008,535 bp in length, with 324 Ns, and consists of 42 scaffolds. The G+C content of the draft genome is 50.59%., Annotation conducted on the RAST server using the Glimmer 3 option () predicted 4,615 protein-coding genes (96 noncoding RNAs). A number of predicted virulence factors, phage loci, and motility and chemotaxis genes were identified, which may facilitate pathogenicity in specific environments. The variable genomic regions, especially pathogenicity-related loci, were highly correlated with different environmental factors, including the host species. Further comparison of the genome sequences of strains from different hosts and geographic regions will provide further insights on virulence, functionality, and plant/pest interactions, as well as contribute to the development of specific assays for accurate identification and detection of the path […]
