Evaluating trade-offs in life-history traits of plant pathogens is essential to understand the evolution and epidemiology of diseases. In particular, virulence costs when the corresponding host resistance gene is lacking play a major role in the adaptive biology of pathogens and contribute to the maintenance of their genetic diversity. Here, we...

Taxonomically restricted genes (TRGs), i.e., genes that are restricted to a limited subset of phylogenetically related organisms, may be important in adaptation. In parasitic organisms, TRG-encoded proteins are possible determinants of the specificity of host-parasite interactions. In the root-knot nematode (RKN) Meloidogyne incognita, the...

Nematools project aimed at reinforcing prophylactic methods to prevent introduction and disseminationof regulated phytoparasites nematodes Meloidogyne chitwoodi, M. fallax, Globodera pallida and G.rostochiensis which are serious threats for potato crops and to improve the control strategies in order to preserve the privileged health status of...
