Jasmonic acid-mediated enhanced regulation of oxidative, glyoxalase defense system and reduced chromium uptake contributes to alleviation of chromium (VI) toxicity in choysum (Brassica parachinensis L.)

The goal of our study was to examine the effect of feed supplement Humilid on the antioxidant defense system, free radical processes, and histomorphological changes in the tissues of rats affected by Chromium (VI). Rats were divided into 4 groups. Animals of groups D2 and D3 received Humilid in a dose of 2 ml per kg of body weight for 28 days. From the 14th day of the experiment, rats of groups D1 and D2 were injected by K2Cr2O7 in a dose of 2 mg Cr per kg of body weight daily for 14 days. Control animals were injected with saline solution for 14 days. Results showed that Cr (VI) causes oxidative stress in rat tissues, accompanied by an increase in superoxide dismutase activity, lipid peroxidation products, and a decrease in glutathione peroxidase and glutathione reductase activity. Chromium also caused histopathological changes in the liver and kidney of rats. Watering of rats affected by Cr (VI) with Humilid leads to decreased oxidative processes, activation of the antioxidant defense system, and reduced pathological effects on animal tissues. Our results indicate the positive influence of Humilid on the rat’s organism, inhibiting free radical processes and exhibiting antioxidant, hepatoprotective, and adaptive properties.

In the current investigation, we studied role of Rhododendron leaf extract in Vigna radiata grown under chromium metal stress. We observed that seed treatment with Rhododendron leaf extract resulted in the recuperation of seedling growth under chromium toxicity. Seed treatment with Rhododendron leaf extract significantly improved the contents of anthocyanin and xanthophyll pigments under stress. The antioxidative defense system triggered after Rhododendron extract treatment, resulting in the increased actions of antioxidant enzymes. Oxidative stress induced by the assembly of reactive oxygen species was reduced after Rhododendron extract treatment under chromium toxicity as indicated by the enhanced contents of non-enzymatic antioxidants, namely ascorbic acid, tocopherol, and glutathione. Furthermore, Rhododendron leaf extract treatment under chromium metal stress also encouraged the biosynthesis of organic acids, polyphenols, as well as amino acids in Vigna radiata. Statistical analysis of the data with multiple linear regression also supported that Rhododendron leaf extract can effectively ease chromium metal-induced phytotoxicity in Vigna radiata.
