The two types of aerenchyma are classified according to the formation mechanism, that is, primary aerenchyma formed in fundamental tissues and secondary aerenchyma differentiated from phellogen (secondary meristem). The term “aerenchyma” was originally given to secondary aerenchyma, and its morphogenesis has been researched from the beginning of the 19th century. Secondary aerenchyma is homologous with cork tissue and consists of white spongy tissue structured by living cells with non-suberized walls. It is continuously formed in the stem, hypocotyls, tap root, adventitious roots and nodules in plants with flooding tolerance under flooded conditions. It plays a role in lenticels entering atmospheric O2 into the plant at the stem base and transports O2 to underground tissues. In the flooding-tolerant legume plants, O2 for respiration and N2 for nitrogen fixation are transported to nodules through aerenchyma at the same time. Although the research of the formation mechanism of secondary aerenchyma and its function in aeration is at the fundamental level, it is expected that further progress in the research will lead to a better understanding of how to improve flooding tolerance of crops.
