“…An increase in the Cr level in the growth medium decreased photosynthetic pigments, E, gs, Pn and WUE in the leaves of cauliflower (Figs and ). A Cr‐induced decrease in photosynthesis has been reported previously in many studies (Ali et al , Jabeen et al , Mostofa et al ). Reduction in the gas exchange parameters may be because of the production of oxidative stress induced by Cr (Fig.…”

The present study evaluated the physiological and biochemical mechanisms through which exogenous sodium hydrosulfide (H2S donor) mitigates chromium (Cr) stress in cauliflower. The different levels of Cr included 0, 10, 100 and 200 µM. Results reported that Cr exposure reduced growth and biomass, chlorophyll (Chl) contents, gas exchange parameters and enzymatic antioxidants. Chromium stress enhanced the production of electrolyte leakage (EL), hydrogen peroxide (H2O2) and malondialdehyde (MDA) contents and increased Cr content in the roots, stem, leaf and flowers. Exogenous H2S improved the physiological and biochemical attributes of Cr‐stressed cauliflower. Hydrogen sulfide decreased Cr content in different parts of Cr‐stressed plants, whereas it increased the Chl contents and gas exchange attributes. H2S reduced the EL, H2O2 and MDA concentrations, enhancing the antioxidant enzymes activities in Cr‐stressed roots and leaves compared to the Cr treatments alone. Collectively, our results provide an insight into the protective role of H2S in Cr‐stressed cauliflower and suggest H2S as a potential candidate in reducing Cr toxicity in cauliflower and other crops.

“…In the present investigation, decreased H 2 O 2 , MDA and PPO activity upon GB and AMF application indicated the ameliorative effect under Cr (VI) toxicity in sorghum. Similar observations have been made by Molla et al (2014) in lentil under Cd stress; Jabeen et al (2016) in mung bean under Cr toxicity; Bharwana et al (2014) in cotton under Pb stress and Ali et al (2015) in wheat under Cr toxicity. Kotb and Elhamahmy, (2014) also reported similar results in wheat plants under salinity stress.…”

Background: Chromium is most toxic pollutant that negatively affects plant’s metabolic activities and yield. It reduces plant growth by influencing the antioxidant defense system’s activities. The aim of the present research was to examine the ameliorative capability of exogenous GB and AMF spiked in soil, either individually or in combination against Cr toxicity. The ameliorative effects were studied in terms of Cr uptake, grain yield, antioxidative defense system parameters (viz. enzymes – SOD, APX, CAT, GR, POX and metabolites – proline, glutathione, ascorbate, β-carotene) and indices of oxidative stress parameters (viz. PPO, H2O2, and MDA). Results:The results delineated that Cr uptake and indices of oxidative stress were increased with increasing concentration of Cr stress in all the varieties (HJ 541, HJ513 & SSG 59-3) at both the growth stages (35 & 95 DAS). At higher concentration (4 ppm), Cr stress decreased the grain yield (45-50%) as compared with controls. PPO activity, MDA and H2O2 content increased at both growth stages in all the varieties. However, antioxidative enzymes and metabolite activities increased due to Cr stress but this increase was not sufficient to counteract with ROS generated under Cr stress which was enhanced on the application of AMF and GB either individually or in combination (spiked in soil). It decreased the indices of oxidative stress and ameliorated the Cr toxicity and increased grain yield (65-70%) in all the varieties. Conclusions:Both GB and AMF, improved the plant growth and stress tolerance capacity of the plant. GB at both 50 and 100 mM level, significantly ameliorated Cr (VI) toxicity. However, AMF concomitantly with GB further boost up the amelioration behavior of the plant against Cr toxicity, at both growth stages in all the varieties. The combination of 100 mM GB with 10 g AMF was observed most effective among all the treatments. Among the varieties SSG 59-3 had the lowest chromium uptake, indices of oxidative stress, and highest antioxidative system’s activity as compared to HJ 513 followed by HJ 541 variety. Thus AMF and GB either individually or in combination may be used to maintain plant yield attributes under Cr toxicity.

“…In plants, chromium toxicity is associated with the increasable production of ROS and oxidative stress development as well as with inhibition of pigment synthesis and modification of virtually all cellular components (Farooq et al 2016;Jabeen et al 2016;Ahmad et al 2017;Uliana et al 2018;Yang-ErChena et al 2018). These metabolic changes result in seedling development, cell death, reduction of plant biomass and crop yield (Antoniadis et al 2017;Yang-ErChena et al 2018) reduction of soluble protein content (Singh et al 2012;Das et al 2014;Jabeen et al 2016) and membrane stability (Begum et al 2016). Plants subjected to chromium also showed reduced growth in this study.…”

Heavy metal chromium (Cr) is considered to be a serious environmental contaminant due to its toxic effect on living organisms. To mitigate and reduce the negative impacts of Cr in rice plant, the effect of exogenous supplementary calcium was evaluated as it functions as a signaling molecule at cellular level. In this study, growth parameters, protein content, and membrane stability were found to be restored due to calcium under Cr stress. Further, Atomic absorption spectrophotometric analysis revealed that calcium inhibits Cr translocation from root to shoot in rice seedlings. This event was addressed by the enhanced accumulation of phytochelatin that leads to vacuolar sequestration of Cr in roots. Furthermore, increased activity of Catalase, Peroxidase, and Glutathione reductase along with elevated glutathione also assures that calcium enhances antioxidant defense mechanism to cope with Cr toxicity.
