Les nématodes à galles du genre Meloidogyne sont des parasites obligatoires du sol extrêmement polyphages. Ils sont considérés comme l'un des pathogènes les plus dévastateurs au monde. La méthode la plus simple et la plus efficace pour lutter contre les nématodes à galles était la lutte chimique. Cependant, la législation sur les produits...

Root-knot nematodes (RKNs) heavily damage most solanaceous crops worldwide. Fortunately, major resistance genes are available in a number of plant species, and their use provides a safe and economically relevant strategy for RKN control. From a structural point of view, these genes often harbour NBS-LRR motifs and are organized in syntenic...

Root-knot nematodes (RKNs), Meloidogyne spp., are extremely polyphagous plant parasites worldwide. Since the use of most chemical nematicides is being prohibited, genetic resistance is an efficient alternative way to protect crops against these pests. However, few resistance genes (Rgenes) are available and some nematode populations may become...

Root-knot nematodes, Meloidogyne spp., are extremely polyphagous plant parasites worldwide. Since the use of most chemical nematicides is being prohibited, genetic resistance is an efficient alternative way ta protect crops against these pests. However, resistance genes (R-genes) are limited and nematode populations are able ta overcome them...

Key message The plant genetic background influences the efficiency of major resistance genes to root-knot nematodes in pepper and has to be considered in breeding strategies. Root-knot nematodes (RKNs), Meloidogyne spp., are extremely polyphagous plant parasites worldwide. Since the use of most chemical nematicides is being prohibited, genetic...

With the banning of most chemical nematicides, the control of root-knot nematodes (RKNs) in vegetable crops is now based essentially on the deployment of single, major resistance genes (R-genes). However, these genes are rare and their efficacy is threatened by the capacity of RKNs to adapt. In pepper, several dominant R-genes are effective...
