#aerotropism

• Aerotropic — Relating to aerotropism; exhibiting an orientation movement or a directed growth reaction of plant vegetative organs (roots, stems) under the direct influence of atmospheric air or local oxygen concentration. The term describes the biological properties of plant tissues reacting structurally to the presence of various gases in the surrounding environment.
• Aerotropism — 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.
