“…Phosphorus is an essential macroelement that not only stimulates plant growth but also affects plant responses due to its direct involvement in energy production (ATP) and signaling cascades by mediating phosphorylation of various proteins [4,6,38]. Thus, P deficiency impairs nutrient homeostasis, leading to massive physiological and metabolic changes in plants [37,46].…”

“…On a global scale, about 5.7 billion hectares of lands (30-40% of arable lands) suffer from the P-deficiency problem. Low availability of inorganic P is due to its inherent binding tendency with cations (Fe 3+ and Al 3+ ) and conversion to organic matter through soil-microbial degradation [6]. Therefore, it is important to enhance P uptake capacity of plants to sustain crop production under P-limited conditions.…”

Phosphorus (P) deficiency in soils is a major problem for sustainable crop production worldwide. Silicon (Si) is a beneficial element that can promote plant growth, development and responses to stresses. However, the effect of Si on tomato (Solanum lycopersicum L.) growth, photosynthesis and mineral uptake under P deficit conditions and underlying mechanisms remain unclear. Here, we showed that low P (LP) supply inhibited tomato growth as revealed by significantly decreased fresh and dry weights of shoots and impaired root morphological traits. LP-induced growth inhibition was associated with decreased photosynthetic pigment content, net photosynthetic rate (Pn), stomatal conductance, transpiration rate and water use efficiency. However, exogenous Si application alleviated LP-induced decreases in growth and physiological parameters. In particular, Si increased Pn by 65.2%, leading to a significantly increased biomass accumulation. Biochemical quantification and in situ visualization of reactive oxygen species (ROS) showed increased ROS (O2−· and H2O2) accumulation under LP stress, which eventually elevated lipid peroxidation. Interestingly, exogenous Si decreased ROS and malondialdehyde levels by substantially increasing the activity of antioxidant enzymes, including superoxide dismutase, peroxidase, and catalase. In addition, Si increased concentrations of osmoregulatory substances, such as proline, soluble sugar, soluble proteins, free amino acids, and organic acids under LP stress. Analysis of major element concentrations revealed that exogenous Si application under LP stress not only increased Si uptake but also enhanced the concentrations of most essential elements (K, Na, Ca, Mg, Fe, and Mn) in different tissues (roots, leaves, and stems). These results reveal that Si mitigates LP stress by improving photosynthetic capacity, antioxidant potential, and nutrient homeostasis and that it can be used for agronomic management of vegetable crops in P-deficient soils.

“…whereas PA catalyzes mainly the cleavage of glycans but it also contains phytase for the hydrolysis of phytic acid, usually found in high quantities in grains. 43,44 Phytic acid is usually associated with proteins residues in beans, seeds, nuts, grains, and other vegetables 45 ; nonetheless, its presence in mammals has not been reported in the literature. Overall, the most thorough analysis in terms of lectins stains was carried out for ZYC and ZYP; the mixtures which were firstly tested.…”

“…Ammonia, nitrate, nitrite, dissolved oxygen, and total suspended solids were directly obtained from the watershed model. The output value of mineral phosphorus was considered as phosphate since it usually occurs in nature as part of the latter (Bhattacharya, 2019). SWAT simulates algae biomass as chlorophyll-a, which is a specific form of chlorophyll that absorbs violet-blue and orange-red light and reflects greenyellow lights.…”

Wildfires are an increasing threat in the Mediterranean region, causing frequent losses of goods and human lives. Not only are wildfires a concern due to their immediate effects on vegetation and soil, but they can also have substantial impacts on surface water quality. Approximately one-third of the world’s largest cities obtain their drinking water from forest catchments. The removal of vegetation and consequent runoff increase with a high concentration of ash and sediment often leads to increased nutrient and contaminant loads to downstream reservoirs, damaging the aquatic ecosystem and threatening human health. This study focused on the post-fire degradation of surface water in Castelo de Bode reservoir, a strategic freshwater supply for Lisbon’s metropolitan area (2,000,000 inhabitants), Portugal. Output data from the catchment model Soil and Water Assessment Tool were used as inputs to the CE-QUAL-W2 reservoir model. CE-QUAL-W2 was then calibrated for water level, temperature, nutrients, total suspended solids, chlorophyll-a, and dissolved oxygen. The post-fire impacts were assessed by adjusting land use features (curve number, crop vegetation management factor), and soil properties (soil erodibility) in the catchment model, considering the different impacts of fire (low, medium, and high severity). The reservoir model was able to perform temperature seasonality and stratification while a weak performance was found for chlorophyll-a probably for having considered only a group of algae. Simulations showed a deterioration of water quality at the dam wall during the first year after the forest fire. Nevertheless, contamination did not appear worrisome with regards to water quality standards likely due to the capability of the reservoir to attenuate inflow concentrations.
