A tissue present in plants helps in storing food and sideways conduction of water. ‘In waterlogged soils, plants strongly influence soil oxygen availability by transporting oxygen through aerenchyma to soils.’ ‘There are large intercellular spaces between the irregular cells, and the parenchyma looks like aerenchyma.’ ‘Programmed cell death also takes place in the cortex of adventitious roots to form aerenchyma.’ into activators or repressors, and the activator-type ARFs con-tain a glutamine (Q)-rich middle region (17). Aerenchyma definition, a tissue in certain aquatic plants, consisting of thin-walled cells and large intercellular spaces adapted for internal circulation of air. Parenchyma tissue is one of the three types of ground tissues in plants. Simple permanent tissues are again classified into three main types. Ø They provide buoyancy to the plants to balance in the water. Aerenchyma is an airy tissue found in roots of plants, which allows exchange of gases between the shoot and the root. This types of parenchymatous tissue is called aerenchyma. Compared to intracellular spaces, aerenchyma tissue possesses enlarged gas spaces which allow distinguishing them from other tissues. Aerenchyma is majorly found in aquatic and wetland plants. Such a parenchyma type is called aerenchyma. Sclerenchyma is one of the three types of ground, or fundamental, tissue in plants; the other two types are parenchyma (living thin-walled tissue) and collenchyma (living support tissue with irregular walls). In aquatic plants, large air cavities are present in parenchyma to give buoyancy to the plants to help them float. There are two types of aerenchyma: lysigenous and schizogenous. Aerenchyma refers to spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root..

Ø Respiratory gases (CO2 or O2) stored in aerenchyma can be utilized by the plants when required. Therefore, existence of two types of aerenchyma has been suggested in rice roots: one is inducible aerenchyma, which forms in low-oxygen environments; the other is constitutive aerenchyma, which fundamentally forms in the absence of external environmental stress as an integral part of ordinary root development … The Aerenchyma is like foam rubber on a microscopic scale. Aerenchyma tissues form gas-conducting tubes that provide roots with oxygen under hypoxic conditions. aerenchyma- found in aquatic plants to help in buyoncy of air. Although aerenchyma have received considerable attention in Zea mays , the signaling events and genes controlling aerenchyma induction remain elusive.
