Genetic and Molecular Strategies for the Cloning of (A)Virulence Genes in Sedentary Plant-Parasitic Nematodes

In some cases, crop resistance can be overcome by virulent nematode pathotypes, which are able to reproduce on plant carrying a resistance gene. The understanding of the molecular determinants of (a)virulence in the nematode is essential to the development of new and more durable forms of resistance. In this review will be presented the current strategies designed to identify and isolate (a)virulence genes in cyst and root-knot nematodes, in relation with the mode of reproduction of these two groups.
