ABSTRACT
Respiration is very sensitive to waterlogged conditions. Under these conditions, plant roots suffer from lack of available oxygen. In fact, waterlogging reduces the exchange gases between and atmosphere. When plants cannot receive sufficient oxygen level for respiration, they form aerenchyma in their which function as reservoirs submerged plant. Aerenchyma formed maize (Zea mays) response different types stress such waterlogging, mechanical impedance, drought nutrient deficiencies. Ethylene plays a crucial role formation. it can be cumulated tissue induces genes implicated These are related calcium signaling, cell wall degradation reactive species (ROS). this review, authors focused on recent findings explained mechanisms its formation under Key words: Aerenchyma, root cortex, ethylene, programmed death. &nbsp
