植物和动物一样，是专性需氧菌，但由于它们不能移动，已经进化出适应机制，使它们能够在短时间的低氧供应中生存，例如大雨或洪水后发生的那些。不利的天气条件和次优的土壤和灌溉技术的组合可以导致严重的产量损失，适应短暂低氧条件的分子基础尚未完全表征，但在鉴定低氧条件下诱导的基因和基因产物方面已经取得了进展。参与厌氧诱导基因调控的启动子元件和转录因子已被表征。在本文中的帐户已被用于试图提高作物耐淹性的分子策略。
Plants, like animals, are obligate aerobes, but due to their inability to move, have evolved adaptation mechanisms that enable them to survive short periods of low oxygen supply, such as those occurring after heavy rain or flooding, Crop plants are often grown on soils subject to waterlogging and many are sensitive to waterlogging of the root zone. The combination of unfavourable weather conditions and suboptimal soil and irrigation techniques can result in severe yield losses, The molecular basis of the adaptation to transient low oxygen conditions has not been completely characterized, but progress has been made towards identifying genes and gene products induced during low oxygen conditions. Promoter elements and transcription factors involved in the regulation of anaerobically induced genes have been characterized. In this paper an account is presented of the molecular strategies that have been used in an attempt to increase flooding tolerance of crop plants.
