article_snippet: Heidi Appel (left) and Rex Cocroft (right) previously conducted a study that found plants can identify sounds nearby, such as the sound of eating, and then react to the threats in their environment .

article_snippet: Researchers in Bonn, Germany, found plants give off a gas when under 'attack'.
article_snippet: Super-sensitive microphones picked up a 'bubbling' sound from a healthy plant.
article_snippet: Plants do not actually scream in pain.
article_snippet: The research could help to work out which pieces of fruit and vegetables are likely to stay fresh longer, as a cucumber which is starting to go off produces a squealing sound.
article_snippet: The research builds on a study last year that found plants can identify sounds nearby, such as the sound of eating, and then react to the threats in their environment.
article_snippet: Professor Appel then played back recordings of caterpillar feeding vibrations to one set of plants, but played back only silence to one set of plants.
article_snippet: When caterpillars later fed on both sets of plants, the researchers found that the plants previously exposed to feeding vibrations produced more mustard oils, a chemical that is unappealing to many caterpillars. '
article_snippet: What is remarkable is that the plants exposed to different vibrations, including those made by a gentle wind or different insect sounds that share some acoustic features with caterpillar feeding vibrations did not increase the plants exposed to different vibrations, including those made by a gentle wind or different insect sounds that share some acoustic features with caterpillar feeding vibrations chemical defences,' co-author Rex Cocroft, said. '
article_snippet: This indicates that the plants are able to distinguish feeding vibrations from other common sources of environmental vibration.'
