Positive selection detection of genome from Ralstonia bacterium with the use of HPC cluster. Ralstonia solanacearum is an aerobic non-spore-forming, Gram-negative, plant pathogenic bacterium. R. solanacearum is soil-borne and motile with a polar flagellar tuft. It colonises the xylem, causing bacterial wilt in a very wide range of potential host plants. It is known as Granville wilt when it occurs in tobacco.The project does provide information about the sequences that are responsible for plant pathogenic effects if this bacterium.
