Aerotropism
Definition
A specific form of tropism or oriented growth movement of plant vegetative organs, such as roots or mycelial filaments, determined by the presence of air or the variation of oxygen concentration in the surrounding environment. This structural phenomenon allows plants to guide their roots toward well-aerated soil layers or to develop respiratory structures above water.
