In this study, we developed the first genetic linkage map for the major rice insect pest, the brown planthopper (BPH, Nilaparvata lugens). The linkage map was constructed by integrating linkage data from two backcross populations derived from three inbred BPH strains. The consensus map consists of 474 simple sequence repeats, 43 single-nucleotide polymorphisms, and 1 sequence-tagged site, for a...

In this study we investigated the genetic control of avirulence in the diploid oomycete pathogen Phytophthora infestans, the causal agent of late blight on potato. The dominant avirulence (Avr) genes matched six race-specific resistance genes introgressed in potato from a wild Solanum species. AFLP markers linked to Avr genes were selected by bulked segregant analysis and used to construct two ...
