Verticillium wilt disease has become increasingly serious in many regions in China over the past few years. In this study, the widespread pathogen was identified as Verticillium longisporum (V. longisporum) by mt-SSU rDNA and cytochrome b sequence analysis. By using the primer pair HW1-F/HW1-R, which was designed based on the V. longisporum-specific rDNA-ITS sequence, a real-time PCR assay was developed for rapid and specific detection of the pathogen. The real-time PCR assay enabled sensitive quantification of V. longisporum in artificial and field-infected seedlings. This study provides a method for large-scale screening of Verticillium wilt-resistant resources for Chinese cabbage breeding.
