Detection methods for Ralstonia solanacearum
Ralstonia solanacearum (EPPO A2 quarantine pest) is an heterogeneous species. Comparison of ITS sequences have shown that strains could be separated into 2 divisions, in accordance with RFLP data and 16S rRNA gene sequences: division I and II (including strains of biovar 2 race 3). Specific primers were selected for the identification of these two divisions. In addition, a new multiplex PCR was developed for the routine detection of R. solanacearum in host plants (in particular in potato tubers).
