The impact of global climate change has highlighted the need for a better understanding of how plants respond to multiple simultaneous or sequential stresses, not only to gain fundamental knowledge of how plants integrate signals and mount a coordinated response to stresses but also for applications to improve crop resilience to environmental stresses. In recent years, there has been a stronger emphasis on understanding how plants integrate stresses and the molecular mechanisms underlying the crosstalk between the signaling pathways and transcriptional programs that underpin plant responses to multiple stresses. The combination of flooding (or resulting hypoxic stress) with pathogen infection is particularly relevant due to the frequent co-occurrence of both stresses in nature. This review focuses on (i) experimental approaches and challenges associated with the study of combined and sequential flooding/hypoxia and pathogen infection, (ii) how flooding (or resulting hypoxic stress) influences plant immunity and defense responses to pathogens, and (iii) how flooding contributes to shaping the soil microbiome and is linked to plants' ability to fight pathogen infection.
全球气候变化的影响凸显了更深入了解植物如何应对多种同时或相继出现的胁迫的必要性，这不仅是为了获取关于植物如何整合信号并对胁迫做出协调反应的基础知识，也是为了应用于提高作物对环境胁迫的抗性。近年来，人们更加重视了解植物如何整合胁迫以及支撑植物对多种胁迫反应的信号通路和转录程序之间相互作用的分子机制。由于自然界中这两种胁迫经常同时发生，水淹（或由此产生的缺氧胁迫）与病原体感染的组合尤其值得关注。本综述重点关注：（i）与研究水淹/缺氧与病原体感染的组合及相继发生相关的实验方法和挑战；（ii）水淹（或由此产生的缺氧胁迫）如何影响植物对病原体的免疫和防御反应；（iii）水淹如何影响土壤微生物群落的形成以及与植物抵抗病原体感染的能力之间的联系。
