Summary: This study characterized the agronomic traits, gas exchange, and chlorophyll traits of two wheat genotypes that differ in phosphorus use efficiency (PUE). The results showed that the genotype with higher PUE exhibited better agronomic traits and photosynthetic capacity. These findings are important for screening for crop varieties with high PUE.

Summary: Cyanobacterial blooming caused by temperature and nutrient changes in ponds/lakes with agricultural runoff is a serious issue. The toxins in cyanobacteria can harm aquatic organisms, animals, and humans. This study focuses on using iodine and hydrogen peroxide, alone or in combination, to degrade Microcystis aeruginosa, which is known for its consistent blooming. The results showed that the IH solution completely destroyed the cells of M. aeruginosa, leading to pigment loss, biochemical degradation, and oxidative damage. It removed nearly all phycocyanin and allophycocyanin, as well as a significant amount of carbohydrates and proteins.

Summary: The integration of luminescent ligands into metal-organic frameworks has attracted extensive research interest due to their remarkable luminescent properties. In this study, a Co-MOF with weak fluorescence emission was synthesized and its fluorescence was significantly enhanced by integrating a small amount of luminescent ligands. This enhanced fluorescence could be selectively quenched by organophosphorus pesticides, making it a potential highly selective probe for detecting pesticide residues in food and domestic water.

Summary: In this study, a rapid and sensitive fluorescence assay was developed for detecting organophosphorus pesticides. The assay utilized TAMRA-labeled aptamer and cDNA with extended guanine bases, and upon binding to the pesticide, the TAMRA fluorescence was recovered. The method showed good sensitivity and was successfully applied for the analysis of profenofos in vegetables.

Summary: It was found in this paper that OliGreen emits strong fluorescence in rigid T-Hg2+-T DNA structure compared to poly T. A label-free fluorescent sensor based on OliGreen was proposed for detecting organophosphorus pesticides by constructing T-Hg2+-T DNA structure. The sensor works by monitoring the fluorescence intensity change of OliGreen, which remains strong in the presence of OPs due to the rigid T-Hg2+-T DNA structure.

Summary: An ultrasensitive detection method for glyphosate using a Cu2+-modulated DNA-AgNCs sensor was developed, demonstrating a combination of static and dynamic quenching modes with Cu2+-triggered fluorescence quenching. The sensor showed high linearity for glyphosate analysis in the range of 15-100 μg/L and a low detection limit down to 5 μg/L, making it promising for pesticide residues detection in real samples.

Summary: Transgenic rice lines L-8 and L-23 showed enhanced physiological and photochemical attributes under varying levels of salt stress compared to the wild type control. L-23 exhibited greater tolerance and improved performance in terms of relative water content, stomatal conductance, performance index, maximal photochemical yield of PSII, and chlorophyll content index, highlighting the potential benefits of these transgenic lines in salt-stress conditions.

Summary: The study revealed significant impacts of seasonal climatic factors on the photochemical performance of terrestrial mosses, with different species developing various mechanisms to cope with adverse abiotic stresses. Some moss species showed good adaptation to habitat temperature and water pattern changes, although they still experienced reduced CO2 assimilation efficiency during drier months, while others were more susceptible to seasonality, especially during periods of lower rainfall and relative humidity. Certain moss species were identified as ideal ecological indicators for photosynthetic acclimation to stressed environments due to their sensitivity to water pattern changes resulting from climate change.

Summary: This study aimed to evaluate the health risks of exposure to chlorpyrifos (CPF) among pregnant women in Isfahan province, Iran. The concentration of 3, 5, 6-trichloro-2-pyridinol (TCP), the major metabolite of CPF, was measured in urine samples from 110 pregnant women. TCP was detected in over 70% of the samples, indicating widespread exposure. The estimated daily intake of CPF exceeded the suggested reference dose for chronic exposure in some participants, and Monte-Carlo analysis revealed that chronic toxic effects are expected in at least 20% of the study population.

Summary: Bacteria generate and release extracellular reactive oxygen species (eROS), which significantly contribute to the natural ROS pool and play a crucial role in metabolic interactions of bacteria with their environment. Understanding the behavior of eROS-generating bacteria and its environmental implications is of great importance in the cycling of biogeochemical elements, transformation of organic matter, and regulation of antibiotic resistance genes.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.

Summary: The incomplete recycle of residual mulch film (RMF) in recent years has led to an increase in plastic fragments in soil, posing a serious threat to the soil ecological environment. In this study, seven potential plastic-degrading microorganisms were screened and identified from film-mulched vegetable fields. The degradation ability experiments showed that both single strains and mixed strains demonstrated varying levels of degradation of RMF.

Summary: This study investigated the degradation of heat-treated wood by brown rot fungi and found that the decay increased the hygroscopicity of wood in the decaying state. Furthermore, it was observed that heat-treated samples were more susceptible to fungal decay compared to untreated samples, which may be related to the increase in moisture content.

Summary: This study investigated the phenomenon of Centimetric circular areas Uncolonized by Microbial Biofilms (CUMBs) on natural and heritage stone surfaces. The analysis revealed a compatibility in distribution and size between CUMBs and lichen thalli, suggesting a lichen origin for some CUMBs. Microscopic analysis also showed similar modifications in marble layers beneath CUMBs and lichens, indicating a possible alteration of stone properties by lichens.
