Xanthomonas oryzae pv. oryzae Genome sequencing and assembly. Xanthomonas oryzae pv. oryzae

The Gram-negative plant pathogenic Xanthomonas oryzae pv. oryzae (Xoo) is the causal agent of bacterial blight (BB) disease on rice. BB represents a well-known case of evolutionary arms race between pathogens and their hosts. To investigate the evolutionary relationships and transcriptional diversity between and within the different Xoo races, we re-sequenced 23 representative strains of key Xoo races from China and Philippines, and generated a RNA-Seq data set at the time-point of 16 h cultured in hrp-inducing media XOM2. In total, 19.5 GB high-quality bases with an average sequencing depth of 172.9±4.3X for each strain were generated and 33,006 SNPs were obtained in the 23 Xoo strains. 4208±54 expressed genes were observed based on the 224,602,862 mapped unique pair-end reads. The genome and transcriptome datasets generated in this study can be used on comparative genomic research to further understanding of the evolution of Xoo.
