Abstract
Loop-mediated isothermal amplification (LAMP) was designed to rapidly detect biovars 1 and 3 of Pseudomonas syringae pv. actinidiae (Psa), a serious, global kiwifruit pathogen, using two primer sets targeting biovar-specific type III effector genes. Each primer set was specific for the targeted biovars, and no signals were obtained for any other biovars. Detection limits of the assay were tenfold higher than that of the conventional PCR method for both biovars. The primer set to detect biovar 3 was highly sensitive at detecting this biovar directly from leaf lesions.
