“…Therefore, SOD is important for tolerating P stress and could be considered essential for mycorrhizal colonization of maize plants grown in calcareous soil. These results corroborate the observations of Singh et al (2018), who found enhanced SOD activity under P deficiency in wheat (Triticum aestivum L.) cultures. Singh (2015) reported that SOD activity in non-mycorrhizal tomato plants was higher than in mycorrhizal plants cultivated under appropriate water levels.…”

Influence of Local Isolates of Arbuscular Mycorrhizal Fungi on Growth and Some Physiological Performance of Zea mays Grown in Calcareous Soil as Affected by Phosphorus Levels

A RBUSCULAR mycorrhizal fungi (AMF) are fungi that form symbiotic relationships with the roots of higher plants. AMF can potentially be applied to enhance plant tolerance to stress and thus minimize the deleterious effects of abiotic stress. Deficiencies in phosphorus, an essential macronutrient for plants, can have negative effects. Our target was to determine the mitigation effect of local AMF inoculum on the growth and metabolic activity of Zea mays at different phosphorus levels (from 0 to 120mg P kg −1 soil). Phosphorus deficiency disturbed physiological performance; however, AMF mitigated associated negative effects, enhanced dry weight significantly (P< 0.05), and increased P and alkaline phosphatase levels in calcareous soil compared with non-inoculated controls. The maximum H + -ATPase activity was 28.13µmoL Pi −1 ng P −1 min in the leaves of Z. mays in AMF-inoculated soil treated with 60mg P kg −1 soil. AMF enhanced the activities of the antioxidant enzymes superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase together with their substrates glutathione and ascorbic acid, with concurrent reductions in lipid peroxidation and hydrogen peroxide content. The highest mycorrhizal colonization (88%) was recorded in maize grown with 60 mg P kg −1 soil. Established data on morphological characteristics revealed that the local AMF isolates contained four native spores related to the genera Glomus, Acaulospora, Scutellospora, and Entrophospora. Analysis of genetic material confirmed that the spores were related to Glomus mosseae and Acaulospora spinose. These findings demonstrate that root colonization via local AMF inoculum could ameliorate phosphorus deficiency in calcareous soils from the northwestern coast of Egypt.

“…The crosses of Vishal x Vijay and ICC 4958 x Vijay recorded less increase in lipid peroxidation rate of 27.68 and 27.88 percent, respectively (Fig 2A). The increase in leaf MDA contents observed under drought stress are consistent with Singh et al (2018) in wheat. In the present study, increased levels of ROS were found under drought stress in chickpea parents and their crosses, as indicated by increased lipid peroxidation rate.…”

Chickpea parents with contrasting root characters and their direct and reciprocal crosses were evaluated under control and drought stress created by withholding irrigation using specially designed root boxes at 50 per cent flowering stage. The crosses involving Vijay and ICC 4958 having deep and prolific root system as a male parent exhibited higher accumulation of osmolytes (proline and glycine betaine) and with higher activities of antioxidative enzymes (SOD, APX, CAT and GPX) with less increase in lipid peroxidation rate and less decrease in nitrate reductase. Amongst the chickpea crosses, the cross of ICC 4958 x Vijay recorded higher increase in root length of 78.77 percent with less reduction in RLWC. The high estimates of broad sense heritability and genetic advance as percent mean was observed in F 2 generations of direct and reciprocal crosses for long root length.

“…In this study, the most noticeable impact on the measured biochemical parameters in wheat spikes had a low nitrogen level itself. Various abiotic stress conditions lead to the overproduction of ROS and imbalanced ROS detoxification, which lead to lipid peroxidation [8,30]. The present study provided similar results, in which low nitrogen level as an abiotic stress factor caused an increase in lipid peroxidation in most varieties.…”

Abiotic and biotic stresses, such as mineral nutrition deficiency (especially nitrogen) and Fusarium attack, pose a global threat with devastating impact on wheat yield and quality losses worldwide. This preliminary study aimed to determine the effect of Fusarium inoculation and two different nitrogen levels on oxidative status and antioxidative response in nine wheat varieties. Level of lipid peroxidation, activities of antioxidant enzymes (catalase, ascorbate peroxidase, glutathione reductase), phenolics, and chloroplast pigments content were measured. In general, wheat variety, nitrogen, and Fusarium treatment had an impact on all tested parameters. The most significant effect had a low nitrogen level itself, which mostly decreased activities of all antioxidant enzymes and reduced the chloroplast pigment content. At low nitrogen level, Fusarium treatment increased activities of some antioxidative enzymes, while in a condition of high nitrogen levels, antioxidative enzyme activities were mostly decreased due to Fusarium treatment. The obtained results provided a better understanding on wheat defense mechanisms against F. culmorum, under different nitrogen treatments and can serve as an additional tool in assessing wheat tolerance to various environmental stress conditions.
