“…Different response of antioxidant enzyme activities to heavy metal toxicity has been reported. Navabpour et al (2020) reported increased SOD, and CAT activities under lead toxicity in wheat. [45] In addition to this, Li et al (2013) in Pistia stratiotes L., [29,34] and Zolinova et al (2013) in barley have shown increased SOD and CAT activity under cadmium toxicity [29].…”

The aim of this study was to investigate the changes of some biochemical parameters during the amelioration after period o short term treatment of wheat with arsenic, cadmium and lead. A decrease was observed in the experimental groups, in which 15 μM, 30 μM, and 60 μM (arsenic, lead, and cadmium) metal ion mixture was applied, in terms of the germination rate depending on the increased concentration, and a decrease was observed in the root and stem dry weights of the plants in all groups. MDA levels were determined to increase at all doses. It was determined that heavy metals accumulated by increasing in the tissues due to the increased concentration of heavy metals in the heavy metal ion-applied groups. There were significant changes in the expression levels of antioxidant enzymes. As a result, it was determined in the study that there were significant changes in some biochemical and physiological parameter�s which are the primary response to oxidative stress in plants exposed to heavy metals, depending on the stress. This reason it can be concluded that arsenic, lead and cadmium contents in media can be the responsible for growth inhibition.

“…The VEGR value was significantly lower than CONT (p = 0.01), E120 (p = 0.0015), and E124 (p = 0.0002) ((one-way ANOVA with Tukey's post-hoc test). The antioxidant capacity of plants under stress conditions either increases or decreases depending on species, stress factors [50][51][52][53][54], and exposure time [55]. We recently showed that after one week of treatment with E120 and E124, leaves' antioxidant capacity of cucumber sprouts was reduced by consuming the scavengers' compounds to counteract the oxidative stress [7].…”

The growing environmental spreading of food synthetic dyes and bio-colors have the potential for altering organisms’ redox states. Here, three model species for aquatic pollution trials, Cucumis sativus seeds, Artemia salina cysts, and Danio rerio embryos, were short-term exposed to a fixed concentration of the artificial red E124, and two red bio-colors, cochineal E120, and vegan red (VEGR). In the animal models, we evaluated the total reactive oxygen species (ROS) and the susceptibility to in vitro oxidative stress, and in C. sativus, H2O2 production and antioxidant capacity. We also measured organismal performance indices (routine oxygen consumption in the animal models, dark oxygen consumption, and photosynthetic efficiency in C. sativus). In C. sativus, only E124 increased ROS and affected dark oxygen consumption and photosynthetic efficiency, while all dyes enhanced the antioxidant defenses. In the A. salina nauplii, all dyes increased ROS, while E120 and E124 reduced the susceptibility to oxidative stress. In D. rerio, treatments did not affect ROS content, and reduced oxidative stress susceptibility. Our data show that red food dyes affect the redox state of the developing organisms, in which ROS plays a significant role. We suggest a potentially toxic role for red food dyes with environmentally relevant consequences.

“…For instance, increased GPX activity helps different plants to improves tolerance to oxidative stress in cucumber ( Cucumis sativus L.), tobacco ( Nicotiana tabacum ), and rice ( Oryza sativa L.) seedlings [ 13 ]; water-deficit stress in wheat ( Triticum aestivum L.) [ 14 ]; salicylic acid-induced salinity stress in tomato ( Solanum lycopersicum L.) [ 15 ]; brassinosteroids-induced low-temperature stress tolerance in tomato [ 16 ]; etc. Similarly, the increased/up-regulated expression levels of GPX genes increased the tolerance to water-deficit stress in wheat [ 14 ]; drought tolerance in Hevea clones [ 17 ]; lead-induced oxidative stress tolerance in wheat [ 18 ]; etc. However, in some cases, the stressed plants also decreased the expression levels of GPX genes; for example, several GPX genes were down-regulated in response to drought stress in sorghum ( Sorghum bicolor L.) [ 19 ].…”

Plant glutathione peroxidases (GPXs) are the main enzymes in the antioxidant defense system that sustain H2O2 homeostasis and normalize plant reaction to abiotic stress conditions. To understand the major roles of the GPX gene family in rapeseed (Brassica napus L.), for the first time, a genome-wide study identified 25 BnGPX genes in the rapeseed genome. The phylogenetic analysis discovered that GPX genes were grouped into four major groups (Group I–Group IV) from rapeseed and three closely interrelated plant species. The universal investigation uncovered that the BnGPXs gene experienced segmental duplications and positive selection pressure. Gene structure and motifs examination recommended that most of the BnGPX genes demonstrated a comparatively well-maintained exon-intron and motifs arrangement within the identical group. Likewise, we recognized five hormones-, four stress-, and numerous light-reactive cis-elements in the promoters of BnGPXs. Five putative bna-miRNAs from two families were also prophesied, targeting six BnGPXs genes. Gene ontology annotation results proved the main role of BnGPXs in antioxidant defense systems, ROS, and response to stress stimulus. Several BnGPXs genes revealed boosted expression profiles in many developmental tissues/organs, i.e., root, seed, leaf, stem, flower, and silique. The qRT-PCR based expression profiling exhibited that two genes (BnGPX21 and BnGPX23) were suggestively up-regulated against different hormones (ABA, IAA, and MeJA) and abiotic stress (salinity, cold, waterlogging, and drought) treatments. In short, our discoveries provide a basis for additional functional studies on the BnGPX genes in future rapeseed breeding programs.
