Plant volatile organic compounds (VOCs) are major vehicles of information transfer between organisms and mediate many ecological interactions . Altering VOC emission in response to herbivore damage has been hypothesized to be adaptive, as it can deter subsequent herbivores, attract natural enemies of herbivores, or transmit information about attacks between distant parts of the same plant. Neighboring plants may also respond to these VOC cues by priming their own defenses against oncoming herbivory, thereby reducing future damage ...

Plants from populations that experienced selection by insect herbivory induced resistance in all neighboring conspecifics by airborne cues, whereas those from populations experiencing herbivore exclusion induced resistance only in neighbors of the same genotype. Furthermore, the information-sharing plants converged on a common, airborne VOC signal upon damage. We demonstrate that herbivory can drive the evolution of plant-plant communication via induction of airborne cues and suggest plants as a model system for understanding information sharing and communication among organisms in general.

See Microphones capture ultrasonic crackles from plants that are water-deprived or injured by Emma Marris.

I've heard some really amazing sounds in a forest! Maybe they were the plants arranging themselves into a phased array and talking to the animals: see Sound from ultrasound, Parametric array and Phased array ultrasonics.

A parametric array, in the field of acoustics, is a nonlinear transduction mechanism that generates narrow, nearly side lobe-free beams of low frequency sound, through the mixing and interaction of high frequency sound waves, effectively overcoming the diffraction limit (a kind of spatial 'uncertainty principle') associated with linear acoustics. The main side lobe-free beam of low frequency sound is created as a result of nonlinear mixing of two high frequency sound beams at their difference frequency. Parametric arrays can be formed in water, air, and earth materials/rock.

See Horizontal gene transfer.

Horizontal gene transfer is the primary mechanism for the spread of antibiotic resistance in bacteria and plays an important role in the evolution of bacteria that can degrade novel compounds such as human-created pesticides and in the evolution, maintenance, and transmission of virulence.
