The number and intensity of flood events will likely increase in the future, raising risk flooding stress terrestrial plants. Understanding effects on plant physiology plant-associated microbes is key to alleviate sensitive species ecosystems. Reduced oxygen supply main constrain its associated microbiome. Hypoxic conditions hamper root aerobic respiration and, consequently, hydraulic conductance, nutrient uptake, growth development. Hypoxia favours presence anaerobic rhizosphere roots with potential negative due their pathogenic behaviour or soil denitrification ability. Moreover, physiological metabolic changes induced by may also cause dysbiotic endosphere microbial composition. holobiont (i.e., host microbiome) can be mitigated once displays adaptive responses uptake. Stress relief could arise from positive effect certain beneficial microbes, such as mycorrhiza dark septate endophytes.
