“…To the best of our knowledge, the effect of salt on heavy metal toxicity has not been investigated in the Brassicaceae halophytes, but in the glycophytes of this family including Brassica napus L. and Brassica juncea (L.) Czem. the combined treatment of salt and Cd had a higher inhibitory effect on the growth and photosynthesis of these species compared to single treatments (Shah et al, 2011).…”

Halophytes exhibit a high cross-tolerance to multiple stresses that enable them to survive under harsh environmental conditions. We hypothesized that salt treatment in halophytes improves their tolerance against other stressors. To investigate the salt-mediated heavy metal tolerance in halophytes, Lepidium latifolium (Brassicaceae) was cultivated in the absence or presence of salt (100 mM NaCl) and excess Zn (200 μM ZnSO4), alone or in combination, for four weeks in the hydroponic medium. Salt treatment ameliorated the reduction of photosynthetic pigments in Zn-stressed plants and decreased Zn accumulation in the young leaves. The activity of peroxidase increased by both Zn toxicity and salt treatments; its maximum activity was achieved under the combination of both treatments associated with a significant reduction in malondialdehyde concentration. The activity of polyphenol oxidase increased by Zn stress alone or in combination with salt, accompanied by accumulation of free and cell wall-bound phenolics and enhanced lignin deposition in the leaves. Our results showed a mitigating effect of salt treatment in Zn-stressed plants through the activation of antioxidant defense and accumulation of phenolic compounds including flavonoids. Our results suggest L. latifolium as suitable species for revegetation and rehabilitation of saline soils contaminated with heavy metals.

“…Our model predicts soybean growth rates that fall within the experimentally determined range of 0.05 − 0.1 g g − 1 DW d − 1 (Ghazali & Cox, 1981; Wells, 1993; Purcell et al ., 1997; Malek et al ., 2012), with lower RGRs being measured as the number of days after sowing increases (Tandale & Ubale, 2007; Arif et al ., 2010; Malek et al ., 2012). The model predicts that in conditions where the rate of photosynthesis is the growth limiting variable, N‐fixation costs a soybean plant slightly less than a third of its RGR compared with growth in which all N is provided as ammonium from the soil.…”

Summary Nitrogen‐fixing symbioses allow legumes to thrive in nitrogen‐poor soils at the cost of diverting some photoassimilate to their microsymbionts. Effort is being made to bioengineer nitrogen fixation into nonleguminous crops. This requires a quantitative understanding of its energetic costs and the links between metabolic variations and symbiotic efficiency. A whole‐plant metabolic model for soybean (Glycine max) with its associated microsymbiont Bradyrhizobium diazoefficiens was developed and applied to predict the cost–benefit of nitrogen fixation with varying soil nitrogen availability. The model predicted a nitrogen‐fixation cost of c. 4.13 g C g−1 N, which when implemented into a crop scale model, translated to a grain yield reduction of 27% compared with a non‐nodulating plant receiving its nitrogen from the soil. Considering the lower nitrogen content of cereals, the yield cost to a hypothetical N‐fixing cereal is predicted to be less than half that of soybean. Soybean growth was predicted to be c. 5% greater when the nodule nitrogen export products were amides versus ureides. This is the first metabolic reconstruction in a tropical crop species that simulates the entire plant and nodule metabolism. Going forward, this model will serve as a tool to investigate carbon use efficiency and key mechanisms within N‐fixing symbiosis in a tropical species forming determinate nodules.

“…Salinity stress is a significant environmental factor that poses challenges to plant growth and development [ 1 – 3 ]. When plants are exposed to high salinity levels in their surrounding soil or irrigation water, it disrupts their normal physiological processes, leading to various detrimental effects [ 4 , 5 ]. One of the primary impacts of salinity stress on plants is inhibited growth [ 6 , 7 ].…”

Salinity stress is a prominent environmental factor that presents obstacles to the growth and development of plants. When the soil contains high salt concentrations, the roots face difficulties in absorbing water, resulting in water deficits within the plant tissues. Consequently, plants may experience inhibited growth, decreased development, and a decline in biomass accumulation. The use of nanoparticles has become a popular amendment in recent times for the alleviation of salinity stress. The study investigated the biological approach for the preparation of Se nanoparticles (NP) and their effect on the growth of wheat plants under saline conditions. The leaf extract of lemon (Citrus limon L.) was used for the green synthesis of selenium nanoparticles (Se-NPs). The synthesized NPs were characterized by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) and were applied foliar in the range of 0.01%, 0.05% and 0.1% on wheat plants. Results showed that 0.1% SeNP alone exhibited a significantly higher yield per plant, biomass per plant, 1000 grains weight, chlorophyll a, chlorophyll b and total chlorophyll over the SS (salt stress) control. A significant decline in MDA and H2O2 also validated the effectiveness of 0.1% SeNP over the SS control.
