Under anaerobic conditions, plants apply a wide spectrum of precise adaptive strategies responding to several critical challenges. The ability of efficiently sensing the oxygen presence demonstrates the existence of both direct and indirect ways of perception. The subsequent coordinate metabolic reassessment is currently under study. The complex molecular response implicates not only transcriptional and translational regulation of specific genes but also posttranscriptional and posttranslational regulatory mechanisms, each and all integrating the metabolic settings. Furthermore, the accumulation of typical metabolites during low oxygen stress condition is a key factor that suggests some critical topics in the regulation of metabolic pathways. Here, we summarize the main routes for adaptive behavior during oxygen depletion, from oxygen availability perception to recently discovered molecular mechanisms and metabolic adaptations.
在厌氧条件下，植物应用广泛的精确适应策略来应对多种关键挑战。有效感知氧气存在的能力证明了直接和间接感知方式的存在。目前正在研究随后的协调代谢重新评估。复杂的分子反应不仅涉及特定基因的转录和翻译调节，还涉及转录后和翻译后调节机制，所有这些机制都整合了代谢状态。此外，在低氧胁迫条件下典型代谢物的积累是一个关键因素，提示了代谢途径调节中的一些关键问题。在这里，我们总结了从氧气可用性感知到最近发现的分子机制和代谢适应缺氧条件下适应行为的主要途径。
