“…Similar results were obtained in Pisum sativum where the inactivation of Mn-SOD by oxidative modification and the downregulation of predominant CuZn-SOD gene expression were observed (Romero-Puertas et al, 2007). However, a Cd-dependent increase of SOD activity in many plant species has been reported in response to Cd: Brassica juncea (Kaur et al, 2019), Mentha arvensis (Zaid et al, 2020, Triticum aestivum (Çatav et al, 2020, while changes in the activity of SOD were not observed in Arabidopsis thaliana plants exposed to low Cd concentration (Smeets et al, 2009). The differences observed could be due to the experimental conditions, Cd concentration, period of treatment and/or the specific strategies used for the different species against the metal .…”

The total antioxidant capacity in roots also increases in B. auriculata plants treated with Cd, probably due to the increase of GSH and AsA, amongst other factors.…”

Biscutella auriculata L. is one of the rare species that is able to grow in a very contaminated mining area in Villamayor de Calatrava (Ciudad Real, Spain). In an effort to understand the mechanisms involved in the tolerance of this plant to high metal concentrations, we grew B. auriculata in the presence of 125 μM Cd(NO3)2 for 15 days and analysed different parameters associated with plant growth, nitric oxide and reactive oxygen species metabolism, metal uptake and translocation, photosynthesis rate and biothiol (glutathione and phytochelatins) content. Treatment with Cd led to growth inhibition in both the leaves and the roots, as well as a reduction of photosynthetic parameters, transpiration and stomatal conductance. The metal was mainly accumulated in the roots and in the vascular tissue, although most Cd was detected in areas surrounding their epidermal cells, while in the leaves the metal accumulated mainly in spongy mesophyll, stomata and trichrome. Based on the Cd bioaccumulation (5.93) and translocation (0.15) factors, this species denoted enrichment of the metal in the roots and its low translocation to the upper tissues. Biothiol analysis showed a Cd-dependent increase of reduced glutathione (GSH) as well as the phytochelatins (PC2 and PC3) in both roots and leaves. Cd-promoted oxidative damage occurred mainly in the leaves due to disturbances in enzymatic and nonenzymatic antioxidants, while the roots did not show significant damage as a result of induction of antioxidant defences. It can be concluded that B. auriculata is a new Cd-tolerant plant with an ability to activate efficient metal-sequestering mechanisms in the root surface and leaves and to induce PCs, as well as antioxidative defences in roots.

“…For example, Cd stress (100 µM CdCl 2 ) resulted in increased MDA and H 2 O 2 in Arabidopsis thaliana [ 103 ] and Cucumis sativus seedlings [ 104 ]. In a recent study, Ahanger et al [ 105 ] reported that lipid peroxidation, EL, H 2 O 2 , and O 2 •− contents as well as LOX activity were markedly increased in V. angularis seedlings under Cd stress (100 µM CdCl 2 , 20 d), while a similar increase in EL, H 2 O 2 and TBARS contents was recorded in Mentha arvensis under Cd stress (50 µM CdCl 2 , 100 d) [ 106 ]. Hasanuzzaman et al [ 107 ] demonstrated higher MDA, H 2 O 2 , and O 2 •− content in wheat plants subjected to lead (Pb) stress (0.5 and 1.0 mM Pb(NO 3 ) 2 ) compared with control.…”

“…Moreover, both GST and GSH contribute in the accumulation of some flavonoids (anthocyanin), which also act as metal binder and may use the same pathway to be accumulated into the vacuole [195,196].

Kosi and Kusha) genotypes pointing out the activation of an antioxidant defense system for conferring Cd toxicity tolerance [ 106 ].

Reactive Oxygen Species and Antioxidant Defense in Plants under Abiotic Stress: Revisiting the Crucial Role of a Universal Defense Regulator

Global climate change and associated adverse abiotic stress conditions, such as drought, salinity, heavy metals, waterlogging, extreme temperatures, oxygen deprivation, etc., greatly influence plant growth and development, ultimately affecting crop yield and quality, as well as agricultural sustainability in general. Plant cells produce oxygen radicals and their derivatives, so-called reactive oxygen species (ROS), during various processes associated with abiotic stress. Moreover, the generation of ROS is a fundamental process in higher plants and employs to transmit cellular signaling information in response to the changing environmental conditions. One of the most crucial consequences of abiotic stress is the disturbance of the equilibrium between the generation of ROS and antioxidant defense systems triggering the excessive accumulation of ROS and inducing oxidative stress in plants. Notably, the equilibrium between the detoxification and generation of ROS is maintained by both enzymatic and nonenzymatic antioxidant defense systems under harsh environmental stresses. Although this field of research has attracted massive interest, it largely remains unexplored, and our understanding of ROS signaling remains poorly understood. In this review, we have documented the recent advancement illustrating the harmful effects of ROS, antioxidant defense system involved in ROS detoxification under different abiotic stresses, and molecular cross-talk with other important signal molecules such as reactive nitrogen, sulfur, and carbonyl species. In addition, state-of-the-art molecular approaches of ROS-mediated improvement in plant antioxidant defense during the acclimation process against abiotic stresses have also been discussed.
