Root-lesion nematodes (Pratylenchusspp.) and arbuscular mycorrhizal fungi (AMF) occupy the same ecological niche in the phytobiome of many agriculturally important crops. Arbuscular mycorrhizal fungi can enhance the resistance or tolerance of a plant toPratylenchusand previous studies have been undertaken to investigate the relationship between these organisms. A restructuring of the AMF phylum Glomeromycota has reallocated the species into genera according to molecular analysis. A systematic review of the literature was synthesized to assess the interaction betweenPratylenchusspp. and AMF using the revised classification. Plants inoculated with AMF generally exhibited greater tolerance as demonstrated by increased biomass underPratylenchuspressure. Species of AMF from the order Diversisporales tended to increasePratylenchuspopulation densities compared to those from the order Glomerales. Species from the generaFunneliformisandGlomushad a reductive effect onPratylenchuspopulation densities. The interaction between AMF andPratylenchusspp. showed variation in responses as a result of cultivar, crop species, and AMF species. Putative mechanisms involved in these interactions are discussed.
