ResumenTwo different molecular tools for the diagnosis of the cereal and legume root-lesion nematode Pratylenchus thornei were developed. A randomly amplified DNA (RAPD) fragment specific to P. thornei was identified. After sequencing the fragment, longer primers were designed that complement the terminal sequences of the RAPD fragment, and this pair of specific primers was used to amplify the sequence-characterized amplified region (SCAR). Using the developed pair of SCAR primers, the SCAR fragment specific to P. thornei was easily amplified with DNA extracts obtained from different life stages of the nematode. The described SCARPCR- based assay has the potential to be optimized for routine practical diagnostic tests. In addition, the use of a species-specific satellite DNA sequence to distinguish P. thornei from other Pratylenchus spp. is discussed.
