In a greenhouse study we examined whether soil microorganisms could mediate plant defence against plant-feeding nematodes. Growth, nutrient contents and root exudation of three plant species (Plantago lanceolata, Holcus lanatus, Lotus corniculatus) and the performance of nematodes and fungal communities in the rhizospheres were measured. 3. The plant species differed in their effects on plant-feeding nematodes; however, the addition of soil microorganisms did not enhance nematode control. Nematode addition changed root exudation patterns and rhizosphere fungal community structure in a plant species-specific manner. Glucose levels in the root exudates of all three examined plant species were enhanced, and P. lanceolata root exudates contained higher levels of fumaric acid when nematodes had been added. 4.
