完成几乎所有已知的后生动物生命周期都需要氧气，但许多后生动物具有抵御不同程度和不同时期缺氧的能力。秀丽线虫是最常用的模式生物之一，被广泛用作研究缺氧和缺氧生物学的模型，已发现该线虫对不同程度的缺氧具有耐受性。考虑到线虫具有极高的多样性，低氧浓度对线虫耗氧的影响和适应机制因物种而异。在这项研究中，我们使用一种简单的方法来检测四种线虫的耐缺氧能力，其中包括三种自由生活线虫和一种植物寄生线虫。我们发现植物寄生线虫松材线虫在缺氧条件下可以存活14天以上。对受试物种在缺氧诱导过程中的行为和氧气感受基因谱系的比较表明，松材线虫和线虫之间存在不同的氧气感受系统，它们会迅速引入暂停生命，以响应缺氧的耗尽，以在长期缺氧中生存。
Oxygen is required for the completion of almost all known metazoan lifecycles, but many metazoans harbour abilities to withstand varying degrees and periods of hypoxia. Caenorhabditis elegans, one of the most popular model organism is extensively used as a model for the study of hypoxia and anoxia biology and it has been found that this nematode is capable of tolerance to varying degrees of hypoxia. Considering the extremely high diversity of nematodes, the effects of low oxygen concentration and mechanisms of adaptation to oxygen depletion differ among species. In this study, we used a simple assay to examine anoxia tolerance in four nematode species, including three free-living and one plant parasitic nematode. We found that the plant parasitic nematode Bursaphelenchus xylophilus can survive more than 14 days under anoxic conditions. Comparisons of behaviour during anoxia induction and the repertoire of oxygen sensation genes among the tested species suggested the existence of different oxygen sensation systems between B. xylophilus and C. elegans, which quickly introduce suspended animation in response to oxygen depletion to survive long-term anoxia.
