Bacterial odours: a way of communication

Communication, the exchange of information, is essential for interactions between living organisms. The universal language for communication is not speech, but chemical signals. Some of these, known as volatile compounds or "odours," are transmitted through the air. Bacteria play a key role in mutualistic relationships with plants, and their volatile compounds help strengthen this connection. When plants detect bacterial odours, they grow better, develop more roots, and become more resilient to environmental stresses like drought and heat. These odours also serve as warning signals, helping plants defend against harmful fungi.

Using bacteria and their volatile compounds in agriculture offers a sustainable alternative to synthetic fertilizers and pesticides. These compounds are naturally degradable, unlike chemicals that can accumulate in soil or contaminate water sources.
