Analysis of repetitive DNA sequences from potato cyst nematodes and their use as a diagnostic probes

The potato cyst nematode species Globodera rostochiensis and G. pallida pathotype Pa2/Pa3, as well as G. pallida pathotype Pal, can be distinguished from each other by restriction fragment length polymorphisms using DNA probes, which are present at low frequencies in the nematode genome. By differential screening of nematode DNA we have isolated DNA sequences that are highly abundant in G. rostochiensis, G. pallida, or the G. pallida Pal pathotype (...)
