“…Waterlogging stress is a major production constraint for grain legumes such as mungbean ( Amin et al, 2017 ), black gram ( Kyu et al, 2021 ), pigeonpea ( Tyagi et al, 2023 ), soybean ( Sathi et al, 2022 ), which are highly vulnerable to waterlogging stress, particularly during early crop growth stages. Further, climate change models projected that crop productivity would decline more frequently due to waterlogging and other abiotic constraints ( Caretta et al., 2022 ).…”

As the best-fit leguminous crop for intercropping across time and space, mungbean promises to sustain soil health, carbon sequestration, and nutritional security across the globe. However, it is susceptible to waterlogging, a significant constraint that persists during heavy rains. Since the predicted climate change scenario features fewer but more intense rainy days. Hence, waterlogging tolerance in mungbean has been one of the major breeding objectives. The present experiment aimed to employ non-destructive tools to phenotype stress tolerance traits in mungbean genotypes exposed to waterlogging and estimate the association among the traits. A total of 12 mungbean genotypes were used in the present study to assess waterlogging tolerance at the seedling stage. Plant responses to stress were determined non-destructively using normalized difference vegetation index (NDVI) and chlorophyll fluorescence parameters at different time intervals. NDVI and grain yield were positively associated with control (r = 0.64) and stress (r = 0.59). Similarly, chlorophyll fluorescence (quantum yield of PS-II) also had a significant positive association with grain yield under both control (r = 0.52) and stress (r = 0.66) conditions. Hence, it is suggested that NDVI and chlorophyll fluorescence promise to serve as traits for non-destructive phenotyping waterlogging tolerance in mungbean genotypes. With the methods proposed in our study, it is possible to phenotype hundreds of plants for waterlogging tolerance efficiently.

“…Waterlogging and anaerobic conditions are responsible for increased ROS which lead to programmed cell death in plants [114]. Reduced stomatal activity, chlorophyll production, photosynthetic rate, vegetative and reproductive growth, and eventually yield were all effects of water stress [115]. Plants develop survival strategies by shifting metabolic processes toward lowenergy fermentation processes [116].…”

Abiotic stresses like temperature, water, salinity, ultraviolet (UV) radiations, heavy metals, etc., affect plants’ growth and yield. Despite these constraints, plants produce a variety of metabolites to maintain their survival. Primary metabolites, produced through crucial metabolic processes, are essential for plants survival. Additionally, secondary metabolites (SMs) are synthesized from primary metabolites and are mainly used as a defensive mechanism and a means of interacting with unfavorable environmental conditions. In addition to their defensive function in plants, SMs are significant in the pharmaceutical industry. Glycine betaine (GB) is a quaternary ammonium compound that belongs to a class of SMs, present in plants, animals, and microbes. It functions as a compatible solute and reflects potential bioactivity against various abiotic stresses like salinity, water, heat, heavy metals, UV radiations, etc. Due to high solubility and low viscosity, its accumulation is commonly observed in chloroplasts and plastids. The accumulation level generally depends on plant species, growth stage, exposure duration, and stress's nature. GB reduces oxidative stress and prevents the damaging of photosystems and other biomolecules under stressful conditions. It is important for maintaining the water potential and osmotic pressure of cells and hence functions as a potent osmolyte under salinity stress. Excessive production of ROS during temperature stress is responsible for damage to oxygen-evolving complexes, electron transport chains, and photosystems. In order to protect plants from these damages, GB activates the genes responsible for synthesizing heat shock proteins, glycoproteins, and antioxidants via various signaling pathways. GB alleviates the effect of water stress by maintaining the function of rubisco and calcium ion ATPase activity via crosstalk with Abscisic acid (ABA) and ethylene. GB supports the proper functioning of the ascorbate-glutathione cycle, superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase (antioxidative enzymes) to overcome various stresses. Phytohormones like salicylic acid (SA), jasmonic acid (JA), ABA, ethylene, and polyamines (PAS) coordinate well with GB via different signaling pathways to ensure plant protection under various abiotic stresses. The potential bioactivity of GB against various abiotic stresses in plants has been summarized in this review.

“…In addition to the effects mentioned above, waterlogging damages plant roots, which alters leaf physiology and impacts the concentration of chlorophyll (Chl), transpiration rate (Tr), net photosynthetic rate (Pn), stomatal conductance (gs), and net CO 2 assimilation rate (Ci) [7]. It also restricts the growth and biomass accumulation of plants due to decreased CO 2 accumulation and limited uptake of water and nutrients [8]. The overproduction of reactive oxygen species (ROS) and redox imbalance is another detrimental effect of waterlogging on agricultural production losses [9].…”

Waterlogging is one of the key abiotic factors that severely impedes the growth and productivity of soybeans on a global scale. To develop soybean cultivars that are tolerant to waterlogging, it is a prerequisite to unravel the mechanisms governing soybean responses to waterlogging. Hence, we explored the morphological, physiological, biochemical, and transcriptional changes in two contrasting soybean introgression lines, A192 (waterlogging tolerant, WT) and A186 (waterlogging sensitive, WS), under waterlogging. In comparison to the WT line, waterlogging drastically decreased the root length (RL), shoot length (ShL), root fresh weight (RFW), shoot fresh weight (ShFW), root dry weight (RDW), and shoot dry weight (ShDW) of the WS line. Similarly, waterlogging inhibited soybean plant growth by suppressing the plant’s photosynthetic capacity, enhancing oxidative damage from reactive oxygen species, and decreasing the chlorophyll content in the WS line but not in the WT line. To counteract the oxidative damage and lipid peroxidation, the WT line exhibited increased activity of antioxidant enzymes such as peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT), as well as higher levels of proline content than the WS line. In addition, the expression of antioxidant enzyme genes (POD1, POD2, FeSOD, Cu/ZnSOD, CAT1, and CAT2) and ethylene-related genes (such as ACO1, ACO2, ACS1, and ACS2) were found to be up-regulated in WT line under waterlogging stress conditions. In contrast, these genes showed a down-regulation in their expression levels in the stressed WS line. The integration of morpho-physiological, biochemical, and gene expression analyses provide a comprehensive understanding of the responses of WT and WS lines to waterlogging conditions. These findings would be beneficial for the future development of soybean cultivars that can withstand waterlogging.
