“…Waterlogging led to soil oxygen deficiency, resulting in the inhibition of nutrient uptake and transportation, and the decrease of grain yield (Tian et al, 2021). Nitrogen (N) was one of important soil nutrients that affecting crop growth, and organ formation (Kitonyo et al, 2018;Li et al, 2021).…”

“…In recent years, waterlogging occurred frequently at the seedling and flower period of summer maize, and thus affecting maize yield and growth (Ren et al, 2014). The decrease of grain yield after waterlogging may be due to the deficit of soil oxygen, and the inhibition of root ability (Kaur et al, 2020), which leads to changes in the composition and decomposition activities of microbes, the disorder of nutrient recycling process, and the reductions of nutrient absorption and accumulation (Tian et al, 2021). After a prolonged period of waterlogging stress, leaf normal carbon metabolism and nitrogen (N) metabolism is inhibited (Vwioko, Adinkwu & El-Esawi, 2017;Ren et al, 2018), contributing to the degenerated photo-system, and the reduction of N efficiency, and thus limiting physiological processes associated with N, results in a significant yield decrease of summer maize (Vwioko, Adinkwu & El-Esawi, 2017;Ren et al, 2018).…”

Waterlogging was one of the main abiotic stresses affecting maize yield and growth in the North China Plain, while ridge tillage effectually improved soil environment, enhanced crop stress resistance to waterlogging, and increased grain yield of waterlogged maize. In order to explore the responses of nitrogen (N) efficiency and antioxidant system of summer maize to waterlogging stress under different tillage, a field experiment was conducted to explore N use efficiency, leaf activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and malondialdehyde (MDA) content of waterlogged maize Denghai 605 (DH605) and Zhengdan 958 (ZD958) under different tillage system (ridge planting and flat planting). Our results showed that ridge tillage was beneficial to ameliorate waterlogging damages on antioxidant system by increasing SOD, POD, and CAT activities, and decreasing MDA content. Moreover, ridge tillage significantly increased N efficiency of waterlogged maize. N translocation amount (NTA), N translocation efficiency (NTE), N contribution proportion (NCP), N harvest index (NHI), and N use efficiency (NUE) of waterlogging treatment under ridge planting system (W-V3+R) for DH605 was increased by 108%, 69%, 60%, 8% and 16%, while ZD958 increased by 248%, 132%, 146%, 13% and 16%, respectively, compared to those of waterlogging treatment under flat planting system (W-V3). Ultimately, ridge tillage led to a significant yield improvement by 39% and 50% for DH605 and ZD958, respectively, compared to that of W-V3. In conclusion, ridge tillage was conducive to retard leaf aging, and enhance nitrogen efficiency, thereby resulting in a yield improvement of waterlogged summer maize.

“…Under flooding stress, crop yield can be highly reduced (Rhine et al, 2010;Morton et al, 2015;Ding et al, 2020) and even shortterm events of few days can significantly affect wheat growth (Malik et al, 2002). Wheat yield losses due to flooding might range from 10 to over 50% (Jincai et al, 2001;Kaur et al, 2020;Tian et al, 2021), which however, depends on waterlogging duration, wheat genotype, growth stage, soil type and agricultural management.…”

Flooding Causes Dramatic Compositional Shifts and Depletion of Putative Beneficial Bacteria on the Spring Wheat Microbiota

Flooding affects both above- and below-ground ecosystem processes, and it represents a substantial threat for crop and cereal productivity under climate change. Plant-associated microbiota play a crucial role in plant growth and fitness, but we still have a limited understanding of the response of the crop-microbiota complex under extreme weather events, such as flooding. Soil microbes are highly sensitive to abiotic disturbance, and shifts in microbial community composition, structure and functions are expected when soil conditions are altered due to flooding events (e.g., anoxia, pH alteration, changes in nutrient concentration). Here, we established a pot experiment to determine the effects of flooding stress on the spring wheat-microbiota complex. Since plant phenology could be an important factor in the response to hydrological stress, flooding was induced only once and at different plant growth stages (PGSs), such as tillering, booting and flowering. After each flooding event, we measured in the control and flooded pots several edaphic and plant properties and characterized the bacterial community associated to the rhizosphere and roots of wheat plant using a metabarcoding approach. In our study, flooding caused a significant reduction in plant development and we observed dramatic shifts in bacterial community composition at each PGS in which the hydrological stress was induced. However, a more pronounced disruption in community assembly was always shown in younger plants. Generally, flooding caused a (i) significant increase of bacterial taxa with anaerobic respiratory capabilities, such as members of Firmicutes and Desulfobacterota, (ii) a significant reduction in Actinobacteria and Proteobacteria, (iii) depletion of several putative plant-beneficial taxa, and (iv) increases of the abundance of potential detrimental bacteria. These significant differences in community composition between flooded and control samples were correlated with changes in soil conditions and plant properties caused by the hydrological stress, with pH and total N as the soil, and S, Na, Mn, and Ca concentrations as the root properties most influencing microbial assemblage in the wheat mircobiota under flooding stress. Collectively, our findings demonstrated the role of flooding on restructuring the spring wheat microbiota, and highlighted the detrimental effect of this hydrological stress on plant fitness and performance.

“…Hypoxia is one of the major abiotic stresses, primarily caused by numerous flooding events such as waterlogging and submergence (Zhou et al, 2020a ; Xie et al, 2021 ), with deleterious effects on plant growth and development (Bailey-Serres et al, 2012 ; Voesenek and Bailey-Serres, 2015 ; Xie et al, 2021 ; Zhou et al, 2021 ). Due to the excessive water absorption, hypoxia mechanically damages seed germination, seedling establishment, and finally crop yield (Nakayama et al, 2004 ; Arguello et al, 2016 ; Yanjun et al, 2016 ; Striker and Colmer, 2017 ; Wang et al, 2017 ; Shen et al, 2020 ; Lee et al, 2021 ; Tian et al, 2021 ). Further, flooding decreases the seed quality of cotton and soybean by altering the accumulation and distribution of carbohydrates, oil, and protein (Wang et al, 2018 ; Xu et al, 2021 ).…”
