“…Genome-wide association studies (GWAS) overcome this limitation by using a diverse panel of genotypes to find associations between abundant genomic markers and the trait of interest (Elshire et al 2011;Bohra 2013). GWAS has been successfully applied to the study of abiotic stress tolerance in soybean (Zeng et al 2017;Khan et al 2018;Zhang et al 2022). Research on abiotic stresses in plants has already received abundant attention due to the extensive variability of the production environments.…”

Soybean (Glycine max L.) is the most important legume crop in the world, and provides protein and oil for human consumption and animal feed. Cold and waterlogging or flooding are abiotic stress that are commonly encountered during soybean germination in short-season growing conditions in the Northern latitudes. Imbibition of cold water during the germination disrupts the cell membranes and increases leakage of their contents and makes seeds vulnerable to biotic stress. The cold tolerance is associated with the ability of cells to avoid or repair the damage to their membranes and organelles, restoring membrane function, metabolism and managing the reactive oxygen species (ROS) generated during the process. Excess moisture impedes aerobic respiration by oxygen deprivation and increases the likelihood of soil-borne diseases further reducing the germination rate. Tolerance to waterlogging is associated with mechanisms that slow the rate of water uptake and help maintain efficient anaerobic metabolism. The QTL mapping, transcriptomics, and proteomic studies have revealed several genes and pathways that likely play a role in seed response to cold and waterlogging stress. This review discusses the effects of cold and waterlogging on soybean seed germination at the physiological level, the molecular mechanisms involved and provides an overview of soybean waterlogging and cold tolerance research. The methodologies commonly used to study the molecular mechanisms controlling tolerance to waterlogging and cold stress also are reviewed and discussed.

“…Drought has a significant negative impact on output, which has adversely affected soybean quality and yield worldwide (Kuchlan and Kuchlan, 2023). The data showed that the yield of different germplasm resources decreased by 40% ~ 70% under drought stress, which could cause a devastating disaster in soybean production (Zhang et al, 2022). Studies have shown that when plants are subjected to drought stress, a unique defense mechanism is formed in the body (Xu et al, 2008); The longer the stress period, the more reactive oxygen free radicals the cells will produce, which will disrupt the metabolic balance of reactive oxygen species, worsen the peroxidation of membrane lipids and impact crop morphogenesis at the seedling stage (Kachare et al, 2020).…”

Background: Drought is an important factor restricting the development of agriculture. In recent years, plant growth regulators have achieved more results in improving crop stress resistance. The physiological mechanism of exogenous application of mepiquat chloride on soybean seedlings has undergone significant changes under drought stress. Methods: In order to study the effect of exogenous chlorine on the physiology of soybean under drought stress., ‘Heinong 65’ was used as the experimental material, 15% PEG-6000 was used to simulate drought stress and different concentrations of mepiquat chloride solution (100, 300, 500, 700 mg/L) were sprayed at the three-leaf stage of soybean growth by pot method. The dry matter accumulation, auxin (IAA), zeatin (ZA), gibberellin (GA3), abscisic acid (ABA) content and superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX) activity of soybean were determined. Result: The results showed that the activities of antioxidant enzymes SOD, POD, CAT and APX in soybean leaves under drought stress were significantly increased by the treatment of appropriate concentration of mepiquat chloride solution. IAA, GA3 and ZA endogenous hormone levels increased, dry matter accumulation increased, root-shoot ratio and ABA endogenous hormone levels decreased significantly. It can be seen that mepiquat chloride treatment can improve the antioxidant capacity, promote the growth of soybean seedlings under drought stress and effectively alleviate the inhibition of drought stress on soybean growth and development.

“…With the impact of global climate change and intensified human activities, most of the world's land is affected by drought, which is one of the biggest factors affecting crop growth and development (Osmolovskaya et al, 2018;Kaukab and Sowbiya, 2021;Zhang et al, 2022). The yield of maize, as the main food crop in the world, is mainly limited by drought (Saini and Westgate, 2000;Zhou et al, 2011).…”

“…The stem is the main transport organ, which can transport nutrients and water and prop up leaves, flowers, and fruits in a definite space (Shang et al, 2020;Zhang et al, 2021). The leaf is the most important organ for the photosynthesis of plants and has transpiration function, providing the power to absorb water and mineral nutrients from the outside from the root (Liu et al, 2022;Suryanarayanan et al, 2022). The fruit is a reproductive organ, which plays a role in propagation and reproduction.…”

The resource allocation of different component organs of crops under drought stress is a strategy for the coordinated growth of crops, which also reflects the adaptability of crops to drought condition. In this study, maize variety namely ‘Denghai 618’, under the ventilation shed, two treatment groups of light drought (LD) and moderate drought (MD), and the same rehydration after drought are set, as well as the normal water supply for control in shed (CS). The drought experiment was conducted in the jointing–tasseling stage in 2021. The effects of different drought stress on the water content and biomass allocation of each component organ were analyzed. The results showed that (1) during the drought period, the water content of each component organ of summer maize decreased in general, but the Water content distribution ratio (WCDR) of the root increased by 1.83%– 2.35%. The WCDR of stem increased by 0.52%– 1.40%. (2) Under different drought treatments, the root biomass (RB) increased 33.94% ~ 46.09%, and fruit biomass (FB) increased 1.46% ~ 2.49%, the leaf biomass (LB) decreased by 8.2% and 1.46% respectively under LD and MD. (3) The allometric growth model constructed under sufficient water is not suitable for drought stress; the allometric exponent α under drought stress is lower than that of the CS: CS (α=1.175) > MD (α = 1.136) > LD (α = 1.048), which also indicates that the impact of existing climate change on grain yield may be underestimated. This study is helpful to understand the adaptive strategies of the coordinated growth of maize component organs under drought stress and provide a reference for the prediction of grain yield under climate change.
