Plants communicate the onset of an attack from aphids by making use of an underground network of fungi.
Instances of plant communication through the air have been documented, in which chemicals emitted by a damaged plant can be picked up by neighboring plants.
Below ground level, most land plants are connected by fungi called Mycorrhizae.
A new study, published in Ecology Letters, is the first to demonstrate that these fungi also aid in communication.
Researchers from the University of Aberdeen, the James Hutton Institute and Rothamsted Research, all devised a clever experiment to isolate the effects of these thread-like networks of Mycorrhizae.
The team concerned themselves with aphids, that damage plants.
Many plants have chemicals they deploy when aphids attack, that both repel the aphids and attract parasitic wasps, the aphids' natural predator.
The research team grew sets of five broad bean plants, allowing three in each group to develop mycorrhizal networks, and preventing the networks' growth in the other two.
To prevent any through-the-air chemical communication, the plants were covered with bags.
As the researchers allowed single plants in the sets to be infested with aphids, they found that if the infested plant was connected to another by the Mycorrhizal network, the un-infested plant began to mount a chemical defense.
Those unconnected by the networks appeared not to receive the signal of attack, and showed no chemical
