Molecular approaches to the taxonomic position of Peruvian potato cyst nematodes and gene pool similarities in indigenous and imported populations of Globodera

Article Abstract:

Molecular approaches have been used to study taxonomy of Peruvian potato cyst nematodes and gene pool similarities in populations of Globodera, both imported and native. It was a surprise to see that although random amplified polymorphic DNA (RAPD) showed a higher variability in the Peruvian group than in the European one, some characteristic proteins were found using 2-DGE in some European populations although it was not possible to find any in the Peruvian ones.

Life cycle variation and the genetic structure of nematode populations

Article Abstract:

Life cycle variation and genetic structure are discussed as seen in nematode populations. Little available data on population genetic structure in nematode species allows direct comparison of genetic structure of species which have different life cycles. A study using mtDNA sequence data has been carried out to look at genetic structure of a heterorhabditid nematode. Results are compared to data from the literature related to other species.

Sequence polymorphism of 2 pioneer genes expressed in phytoparasitic nematodes showing different host ranges

Article Abstract:

A qualitative investigation of the three pioneer genes, namely Globodera pallida (GP) GPLIA7, GPLIB3 and Globodera "mexicana" GMLIVG9 was carried out to find out the genes involved in pathogenicity. The results showed that the Globodera pallida and Globodera mexicana were under strong diversifying selection pressures and could be involved in pathogenicity.
