Submergence limits plants' access to oxygen and light, causing massive changes in metabolism; after submergence, plants experience additional stresses, including reoxygenation, dehydration, photoinhibition and accelerated senescence. Plant responses to waterlogging and partial or complete submergence have been well studied, but our understanding of plant responses during post-submergence recovery remains limited. During post-submergence recovery, whether a plant can repair the damage caused by submergence and reoxygenation and re-activate key processes to continue to grow, determines whether the plant survives. Here, we summarize the challenges plants face when recovering from submergence, primarily focusing on studies of Arabidopsis thaliana and rice (Oryza sativa). We also highlight recent progress in elucidating the interplay among various regulatory pathways, compare post-hypoxia reoxygenation between plants and animals and provide new perspectives for future studies.
淹没限制了植物对氧气和光的获取，导致代谢发生巨大变化；淹没后，植物会经历额外的压力，包括再氧化、脱水、光抑制和加速衰老。植物对水涝和部分或完全淹没的反应已经得到了很好的研究，但我们对植物在淹没后恢复过程中的反应的理解仍然有限。在淹没后恢复过程中，植物是否能够修复淹没和再氧化造成的损伤，并重新激活关键过程以继续生长，决定了植物是否能够存活。在这里，我们总结了植物在从淹没中恢复时所面临的挑战，主要集中在对拟南芥和水稻的研究上。我们还强调了阐明各种调控途径相互作用的最新进展，比较了植物和动物在缺氧后再氧化过程中的差异，并为未来的研究提供了新的视角。
