Summary: By utilizing a non-targeted LC-MS-based metabolomics method, this study investigated the effects of Cd exposure at different times on the metabolomics of Brassica juncea xylem sap. The findings revealed significant differences in metabolic profiles of the xylem sap after 48 h and 7 days of Cd exposure. Differential metabolites involved amino acids, organic acids, lipids, and carbohydrates, most of which were downregulated and played crucial roles in response to Cd stress. Regulation of various metabolic pathways was observed for resistance against 48-h and 7-day Cd exposure.

Summary: Metallophytes are plants that can tolerate extreme metal concentrations in soil. A study on the Dugald River gossan in Australia found that there was no direct relationship between the occurrence of metallophytes and prevailing soil metal concentrations. Crotalaria novae-hollandiae was identified as a strong polymetallic indicator-type metallophyte that can accumulate high concentrations of metals in its leaves.

Summary: A mild Cu-catalysed Chan-Lam protocol has been developed for the synthesis of unsymmetrical aryl chalcogenides, including selenides and sulfides, in an aqueous micellar medium. The catalytic system consists of a CuBr catalyst, a water-soluble ligand, a surfactant, and air as the terminal oxidant. A diverse variety of diorganyl diselenides/disulfides could be coupled with various aryl, heteroaryl, and styryl boronic acids in water at ambient temperature to afford the corresponding aryl chalcogenide products in good to excellent yields. The aqueous phase can be recycled at least seven times by adding an additional half catalytic amount of CuBr during each subsequent cycle. UV-VIS spectral studies revealed the solubility of both hydrophobic diorganyl diselenides/disulfides and hydrophilic arylboronic acids in water with the help of the surfactant. Transmission electron microscopy studies showed the formation of nanomicelles under the reaction conditions.

Summary: Nowadays, consumers are opting for biopreservation methods, like using sourdough instead of synthetic preservatives in bread. This study investigated the impact of L. plantarum 5L1 on the properties of bread, as well as its antifungal and biopreservation capacity. The results showed significant differences in the bread's properties, with higher levels of L. plantarum 5L1 leading to increased phenolic and lactic acid content, as well as higher alcohol and ester levels. Furthermore, the higher concentration of L. plantarum 5L1 delayed fungal growth and reduced the content of AFB1 and AFB2 compared to the control.

Summary: Transcriptomic analysis revealed gene expression profiles in the gills and hepatopancreas of Macrobrachium rosenbergii in response to Cd2+ stress. Most differentially expressed genes were down-regulated after Cd2+ exposure, with a significantly higher number of DEGs in the gills compared to the hepatopancreas. Key genes such as metallothionein and Hemocyanin were identified in response to Cd2+ stress.

Summary: This study evaluates the effect of Cu(II) and Zn(II) ions on the aggregation of two different forms of beta-crystallins and finds that they induce aggregation through different pathways. Copper ions primarily cause conformational changes and the formation of high-molecular-weight light-scattering aggregates, while zinc ions cause larger protein structural changes and are more aggressive in inducing aggregation.

Summary: The worldwide environmental nitrate problem is gaining increasing attention due to agricultural inputs and decreasing degradation capacity in aquifers. Treatment methods are becoming more important. This study investigated the effects of enhanced denitrification with addition of organic carbon on microbiology at different temperatures. The addition of substrates resulted in major differences in microbial community, and cooling to 10 degrees C further changed the microbiology. The denitrification rates strongly depend on the temperature effect and the microbiology.

Summary: Industrial pollution, wastewater irrigation, and fertilizer application can lead to heavy metal contamination in agricultural soil. Dissolved organic matter in soil plays a key role in the migration and fate of heavy metals. This study found that adding exogenous dissolved organic matter facilitated the dissolution of heavy metals in the rhizosphere soil. Furthermore, the addition of dissolved organic matter increased the uptake of heavy metals by plants.

Summary: This study investigated the regulation of copper on the adsorption of sulfonamides (SAs) and the release of dissolved organic matters (DOMs) by fungi-microalgae pellets (FM-pellets). The results showed that adsorption was the main mechanism for SA removal, and the presence of copper greatly promoted the removal of SAs through ion exchange and adsorption bridging. Furthermore, the study found that FM-pellets responded to copper by forming complexes to alleviate its damage on organisms.

Summary: In boreal forests, the warming winter climate has detrimental effects on young Scots pine seedlings due to changes in snow conditions. The study found that the thickness and quality of snow cover affect the seedlings' exposure to hypoxic, cold, and drought stresses. The expression of genes related to circadian clock and stress protection is influenced by snow cover manipulation. The findings highlight the importance of the photoreceptors and circadian clock system in the adaptation of Scots pine seedlings to different snow conditions.

Summary: This study investigated the root exudates and metabolic characteristics of Puccinellia tenuiflora under alkali stress. The results showed that P. tenuiflora secretes a large amount of phenolic acids and fatty acids under alkali stress, which promotes pH regulation in the rhizosphere and enhances its alkali tolerance. Transcriptomic analysis revealed the upregulation of glycolysis and phenylpropanoid biosynthesis pathways in the roots of P. tenuiflora under alkali stress.

Summary: The composition of superficial deposits and their role in the development of lithobiotic microorganism communities in urban environments were investigated. Superficial deposits contain low molecular weight organic components such as polyols, organic acids, mono- and disaccharides, as well as heavy metals including Fe, Mn, Zn, Cu, Pb, and Cd. Stress-resistant fungi and dark organotrophic bacteria were found to be the main inhabitants of surface sediments.

Summary: Fullerenol can benefit iron-deficient maize plants by alleviating chlorosis symptoms in younger leaf regions, enhancing leaf active iron, and lowering root apoplastic iron. However, it has no observable effects on iron-III deficient plants. Fullerenol does not affect iron-sufficient plants regardless of iron species used as iron sources.

Summary: The present study investigates the effects of fungi and bacteria metabolism on the crystallization patterns. The results demonstrate that Penicillium chrysogenum is capable of releasing both organic acids and extracellular polymer substance (EPS), which significantly impacts the pH of the culture liquid and the crystallization of carbonate and oxalate. The transition from oxalate crystallization to carbonate can occur with changes in microbial community composition and nutritional value medium. These findings contribute to the understanding of the role of fungi and bacteria in the oxalate-carbonate pathway.

Summary: We discovered oxalates formed by brown rot fungi on stone in natural conditions and proposed a model for their formation, confirming the association between metal oxalates in mines and adits and the activity of these fungi. We synthesized biofilm oxalate minerals and oxalates of toxic heavy metals under the action of four species of brown rot fungi on different mineral substrates. Compared to the soil fungus Aspergillus niger, the metabolic activity of brown rot fungi plays a greater role in oxalate crystallization. The potential use of brown rot fungi in environmentally friendly biotechnologies is justified.

Summary: This study found that fullerenes can alleviate copper toxicity in plants, with arginine-functionalized fullerene showing a more pronounced effect. By buffering copper in the root zone, fullerenes can reduce copper transport to the leaves and eliminate oxidative damage. Arginine C60 also demonstrated higher copper removal efficacy. These findings provide a new approach for alleviating copper toxicity in plants.
