Genome Sequence of the Tobacco Bacterial Wilt Pathogen Ralstonia solanacearum

Abstract
Ralstonia solanacearum is a causal agent of plant bacterial wilt with thousands of distinct strains in a heterogeneous species complex. Here we report the genome sequence of a phylotype IB strain, Y45, isolated from tobacco ( Nicotiana tabacum ) in China. Compared with the published genomes of eight strains which were isolated from other hosts and habitats, 794 specific genes and many rearrangements/inversion events were identified in the tobacco strain, demonstrating that this strain represents an important node within the R. solanacearum complex.
