abstract = {Indirect plant defence, the recruitment of antagonists of
herbivores, is well-known above the ground. In spite of
various soil microorganisms acting as antagonists to root
herbivores, it is still largely unknown whether plants can
promote antagonistic microorganisms as an indirect defence
mechanism. 2 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 We conclude that nematodes have
plant species-specific effects on root exudate chemistry and
rhizosphere fungal community composition, but these effects
do not necessarily enhance indirect control of nematodes by
antagonistic microorganisms. More studies on below-ground
plant defence are definitely needed.},
