Plants communicate with each other. That much is known. However, what is not known is how plants communicate using symbiosis. Dr Johnson has reported new work in Ecology letters that shows that plants use symbiotic fungi to enable communication.
Communication also causes interesting secretion by plants when infected by aphids. These secretions that are volatile work very interestingly – they repel aphids but attract the wasps which eat aphids. This is amazing from the point of view of evolution and creation of chemicals that work in such multiple ways.
Either ways, communications are important for populations whether as email, facebook or plant chemicals!
