3 Figure S1. Conventional PCR and BIO-PCR assays targeting fliC gene encoding the flagella subunit. The detection sensitivity of the assays was illustrated for the 5 strains of Ralstonia solanacearum including biovar 2 (race 3) at a high level after enrichment in the BIO-PCR (A) than that in the conventional PCR (B). Dilution series of potato sap sample spiked with each strain were listed in Table 1. M: 100 bp ladder; P: NCPPB 325 DNA serves as a positive control; N: Sterile distilled water serves as a negative control; HN: Healthy potato sap without pathogen serves as a negative control for DNA extraction.
