“…Previous studies have shown that APX activity decreased with increased metal toxicity in Brassica juncea (L.) [65], B. napus [66], and T. Aestivum [18]. Similar results have been observed in various plants subjected to Cr toxicity [11,20,67,68].…”

“…It has been observed in numerous studies that high Cr concentrations increased oxidative stress owing to the role of Cr in increasing the ROS, MDA, and EL contents of root and leaf tissues. This has been reported in various crops such as B. napus L. [61], Zea mays L. [20], O. sativa [57], and Brassica oleracea L. [11]. An increase in H 2 O 2 levels was also observed in O. sativa seedlings subjected to Cr toxicity [59].…”

“…Furthermore, Cr deposition in agricultural soils is a global concern as it is non-biodegradable and adversely affects plant growth by decreasing photosynthetic pigments, which results in decreased productivity [8][9][10][11]. Cr is classified as a non-essential metal as it does not have any major biological functions [12].…”

The ever-increasing industrial activities over the decades have generated high toxic metal such as chromium (Cr) that hampers the crop productivity. This study evaluated the effect of Cr on two chickpea (Cicer arietinum L.) varieties, Pusa 2085 and Pusa Green 112, in hydroponic and pot-grown conditions. First, growth parameters (seed germination, seedling growth, and biomass production) and physio-biochemical parameters (oxidative stress and the content of antioxidants and proline) were measured to evaluate the performance of both varieties grown hydroponically for 21 days at concentrations of 0, 30, 60, 90 and 120 μM Cr in the form of potassium dichromate (K2Cr2O7). In both varieties, significantly deleterious effects on germination and seedling growth parameters were observed at 90 and 120 μM, while growth was stimulated at 30 μM Cr. Significant increases in malondialdehyde and hydrogen peroxide content and electrolyte leakage demonstrated enhanced oxidative injury to seedlings caused by higher concentrations of Cr. Further, increasing concentrations of Cr positively correlated with increased proline content, superoxide dismutase activity, and peroxide content in leaves. There was also an increase in peroxisomal ascorbate peroxidase and catalase in the leaves of both varieties at lower Cr concentrations, whereas a steep decline was recorded at higher Cr concentrations. In the pot experiments conducted over two consecutive years, growth, yield, yield attributes, grain protein, and Cr uptake and accumulation were measured at different Cr concentrations. Pusa Green 112 showed a significant reduction in plant growth, chlorophyll content, grain protein, pod number, and grain yield per plant when compared with Pusa 2085. Overall, our results indicate that Pusa 2085 has a higher Cr tolerance than Pusa Green 112. Therefore, Pusa 2085 could be used to further elucidate the mechanisms of Cr tolerance in plants and in breeding programmes to produce Cr-resistant varieties.

“…Glycine betaine improves the plants growth under heavy metal stress by escalating chlorophyll contents and reducing the oxidative damage [ 47 ]. Glycine betaine safeguard the photosynthetic pigments and machinery that in results in improvement in growth of the plants [ 116 , 117 , 118 ]. Glycine betaine application improves the adverse effects of Cd stress in cotton seedlings, efficiently alleviating the Cd induced decline in plant biomass and its growth.…”

Unexpected biomagnifications and bioaccumulation of heavy metals (HMs) in the surrounding environment has become a predicament for all living organisms together with plants. Excessive release of HMs from industrial discharge and other anthropogenic activities has threatened sustainable agricultural practices and limited the overall profitable yield of different plants species. Heavy metals at toxic levels interact with cellular molecules, leading towards the unnecessary generation of reactive oxygen species (ROS), restricting productivity and growth of the plants. The application of various osmoprotectants is a renowned approach to mitigate the harmful effects of HMs on plants. In this review, the effective role of glycine betaine (GB) in alleviation of HM stress is summarized. Glycine betaine is very important osmoregulator, and its level varies considerably among different plants. Application of GB on plants under HMs stress successfully improves growth, photosynthesis, antioxidant enzymes activities, nutrients uptake, and minimizes excessive heavy metal uptake and oxidative stress. Moreover, GB activates the adjustment of glutathione reductase (GR), ascorbic acid (AsA) and glutathione (GSH) contents in plants under HM stress. Excessive accumulation of GB through the utilization of a genetic engineering approach can successfully enhance tolerance against stress, which is considered an important feature that needs to be investigated in depth.
