Aerenchyma and barrier to radial oxygen loss are formed in roots of Taro (Colocasia esculenta) propagules under flooded conditions. Interestingly, the MT-treated plants under waterlogging stress exhibited decrease expression pattern of ethylene biosynthesis and signaling gene.Ībiko T., Miyasaka S. The application of MT enhanced tolerance to waterlogging stress by triggering the generation of PA biosynthesis, suppression of excessive ROS, and then improved photosynthetic machinery and aerobic respiration. JA inhibits AR growth and inhibits the action of SA under waterlogging. At the same time, the accumulation of SA stimulates the formation of AR primordia. Furthermore, SA triggers a programmed cell death response, which leads to the development of aerenchyma cells. Ethylene enhances the expression of RBOH (NADPH oxidase, respiratory burst oxidase homolog) and induces ROS signals, which finally lead to the formation of ARs and aerenchyma. Ethylene accumulation enhances auxin biosynthesis and transport, and vice versa. In addition, the expression of ACS and ACO5 is induced in rice root aerenchyma under waterlogging, thereby promoting ethylene synthesis. An increased BR level in Sub1A rice genotype induces the expression of GA catabolism gene GA2ox7, which represses GA signaling, so then shoot elongation is inhibited. However, in non-deepwater cultivars, Sub1A negatively regulates the GA response by limiting the degradation of the GA signal inhibitor protein SLR1/SLRL1, which inhibits shoot elongation. Increased ethylene levels (ET) inhibit ABA biosynthesis, which leads to increased GA content and induces shoot elongation in deepwater rice cultivars.

OsEIL1a (an ethylene-responsive transcription factor) promotes SK1/2 transcription and also directly binds the promoter of GA biosynthesis gene SD1, thereby increasing the synthesis of GA, which stimulates shoot elongation. Waterlogging-tolerant plants can improve the rate of ethanol and lactic fermentation by enhancing the expression of ADHs, PDCs, and LDHs, whose gene products temporarily provide ATP for the growth of plants under waterlogging.
