“…The higher MDA content also indicates the destruction of redox balance under higher Cd stress [11,17,30]. Comparable results were reported in many plant species, such as Sassafras seedlings, Amaranthus tricolor, duckweed, Ceratophyllum demersum, and Vigna radiata, which had higher MDA content under increasing Cd stress [11,17,39,41,42]. Therefore, other abiotic stresses also caused a similar increase in MDA content in plants [43,44].…”

This study aimed to investigate the physiological and cellular mechanisms of Sesuvium portulacastrum under heavy metal stress to evaluate possible tolerance and adaptation mechanisms in a metal-polluted environment. The physiological and cellular ultrastructural responses of S. portulacastrum were studied hydroponically under exposure to a range of cadmium (Cd) concentrations (50 µM to 600 µM) for 28 days. The activity of antioxidant enzymes like catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD), changes in chlorophyll, and cellular ultrastructural content were examined. There was no significant difference in chlorophyll content in the leaf under the stress of 300 μM, but 400 μM and 600 μM Cd stress showed significantly decreased chlorophyll content. The SOD activity indicates an increase under the Cd stress of 100 μM for leaves, 300 μM for stems, and 50 μM for roots; after that, the SOD activity gradually decreased with increasing Cd concentrations. But POD activity was considerably increased with increasing Cd stress. CAT activity showed a gradual increase in concentrations until 300 μM of Cd stress and then decreased sharply in roots, stems, and leaf tissues. Cd stress had a considerable impact on the structure of the roots, stems, and leaves cells, such as distorted and thinner cell walls and the deformation of chloroplasts, mitochondria, and other organelles. Therefore, the increased number of nucleolus in the cell nucleus suggests that cells may be able to maintain their protein synthesis in a stressful environment. This study concludes that SOD is the dominant antioxidant enzyme activity during low Cd toxicity (<100 μM), while POD is the dominant enzyme activity during higher Cd toxicity (>100 μM).

“…From numerous studies from the past, it is clear that the antioxidant defense system manages oxidative damage during abiotic stress in plants. The POX activity in the seedling was drastically elevated (2.78 times) at 300 mM NaCl concentration compared to control in mungbean plants (Farheen et al, 2018). Plants have water-soluble antioxidants that make them strongly redox buffered.…”

“…Salinity caused a reduction in chlorophyll and carotenoid contents which in turn resulted in pronounced chlorosis and necrosis in leaves. Leaf chlorophyll content decreased with increasing salt levels in mungbean (Farheen et al, 2018). A decrease in photosynthetic pigments reduced the photosynthetic efficiency of the plants in mungbean plants (Sehrawat et al, 2015).…”

Global food production is seriously threatened by salinity stress, which is becoming more severe due to human activity. For the majority of people worldwide, mungbean is a significant pulse crop and a rich source of protein and calories and hence is rightly marked as “Poor man’s meat” and “rich man’s vegetables”. Salt stress, on the other hand, negatively affects the productivity of the mungbean since it causes decreased germination, reduced growth and development, interrupted photosynthesis, hormonal imbalance and eventually decreased yields. Consequently, developing mitigation strategies to deal with salt stress requires a greater understanding of how plants respond to salinity stress. The present review highlights the detrimental effects of salt stress and the physiological and biochemical tolerance mechanisms in mungbean.
