Plant-mediated 'apparent effects' between mycorrhiza and insect herbivores

    Research output: Contribution to journalArticlepeer-review


    Plants mediate indirect ‘apparent’ effects between aboveground
    herbivores and below-ground mutualistic mycorrhizal
    fungi. The herbivore–plant–mycorrhiza continuum is further
    complicated because signals produced by plants in response
    to herbivores can be transmitted to other plants via shared
    fungal networks below ground. Insect herbivores, such as
    aphids, probably affect the functioning of mycorrhizal fungi by
    changing the supply of recent photosynthate from plants to
    mycorrhizas, whereas there is evidence that mycorrhizas affect
    aphid fitness by changing plant signalling pathways, rather than
    only through improved nutrition. New knowledge of the transfer
    of signals through fungal networks between plant species
    means we now need a better understanding of how this
    process occurs in relation to the feeding preferences of
    herbivores to shape plant community composition and
    herbivore behaviour in nature.
