摘要：instrument. Specificity of the developed assay was tested against 39 strains of X. euvesicatoria and 41 strains of other species in inclusivity and exclusivity panels, respectively. The assay detection limit was 100 fg (~18 genome copies) of genomic DNA and 1,000 fg in samples spiked with tomato DNA. The assay unambiguously detected X. euvesicatoria in infected tomato plant samples. Concordant results were obtained when multiple operators performed the test independently. No false positives and false negatives were detected. The developed LAMP assay has numerous applications in diagnostics, biosecurity and disease management.
