Random Genome Sequencing of Ralstonia solanacearum Strain IVIA 1602 and Comparative Analysis with Strain GMI1000
Ralstonia solanacearum is a β-proteobacterium which affects several hundred plant species and provokes important agronomic losses. Five biovars of this bacterium have been described and they show behavioural differences. In this study a random sequencing of the genome of R. solanacearum strain IVIA...

| Sumario: | Ralstonia solanacearum is a β-proteobacterium which affects several hundred plant species and provokes important agronomic losses. Five biovars of this bacterium have been described and they show behavioural differences. In this study a random sequencing of the genome of R. solanacearum strain IVIA 1602 (race 3, biovar 2), isolated from potato, was performed. The resulting 730 Genomic Survey Sequences (GSSs), representing 6.38% of the complete genome, were compared against the completely sequenced genome of strain GMI1000 (race 1, biovar 3), isolated from tomato, which is the only strain of this species sequenced until now. This comparative analysis showed, as expected, a high degree of similarity, but it also revealed strain-specific regions of the genome as well as a number of insertion/deletion events and chromosomal rearrangements. All together, this comparative analysis gives an overview of the genomic divergence between these two biovars of the R. solanacearum species complex. |
