The major consequence of hypoxia is a dramatic reduction in energy production. At the onset of hypoxia, both oxygen and ATP availability decrease. Oxygen and energy sensing therefore converge to induce an adaptive response at both the transcriptional and translational levels. Oxygen sensing results in stabilization of the transcription factors that activate hypoxia‐response genes, including enzymes required for efficient sugar metabolism, allowing plants to produce enough energy to ensure survival. The translation of the resulting mRNAs is mediated by SnRK1, acting as an energy sensor. However, as soon as the sugar availability decreases, a homeostatic mechanism, detecting sugar starvation, dampens the hypoxia‐dependent transcription to reduce energy consumption and preserves carbon reserves for regrowth when oxygen availability is restored.

缺氧期间的能量和糖信号。

缺氧的主要后果是能源生产的急剧减少。在缺氧开始时，氧气和ATP的利用率都会降低。因此，氧气和能量感应在转录和翻译水平上会融合以诱导适应性反应。氧气感测可激活激活缺氧反应基因的转录因子，包括有效糖代谢所需的酶，从而使植物产生足够的能量来确保生存。产生的mRNA的翻译是由SnRK1介导的，起着能量传感器的作用。但是，一旦糖的可利用性下降，就可以通过一种稳态机制来检测糖的饥饿状况，从而抑制依赖于低氧的转录，从而减少能量消耗，并在恢复氧的可利用性时保留碳储备以供再生。
