Summary: This study investigated the impact of sub-micron polyethylene (PE) and polypropylene (PP) microplastics (MPs) on nitrogen cycling in a soil-soybean system. The results showed that soil containing MPs increased plant nitrogen uptake and the activity of nitrogenase and glutamine synthetase in soybean. MP contamination also affected the abundance and taxonomic profile of rhizosphere bacteria involved in nitrogen cycling. The concentration and polymer type of MPs did not have a significant impact.

Summary: Due to cultivation in greenhouses, cucumbers are vulnerable to root-knot nematode, which leads to decreased yield and quality. This study explored the impact of nematode on the microbial community in cucumber's rhizosphere. The findings provide insights into the composition of bacterial and fungal communities, as well as the potential interactions between microorganisms and nematodes, offering a reference for eco-friendly control methods. Analysis of soil properties and high-throughput sequencing revealed significant differences in nutrient content and enzyme activities between different levels of nematode infestation. The study also identified a stronger effect of nematodes on rhizosphere soil bacteria compared to fungi, and demonstrated a correlation between nematode contamination levels and soil nutrient content.

Summary: Cucumber fruits exhibit extensive variation in morphological features such as size, shape, waxiness, spines, warts, and flesh thickness. Genetic factors influencing floral organ establishment, cell division and cell cycle regulation, hormone biosynthesis and response, sugar transport, trichome development, and cutin, wax, and pigment biosynthesis have been identified as factors influencing cucumber fruit morphology. Understanding and manipulating these genetic factors can lead to the development of cucumber varieties with desired traits and improved qualities for consumers.

Summary: Nitrogen is essential for the growth of oilseed rape, and the diversity and community structure of rhizosphere microbial communities are significantly affected by nitrogen fertilization. The diversity and richness of bacterial communities in the rhizosphere of oilseed rape were lower under low nitrogen application, while higher nitrogen levels maintained a higher community diversity of bacteria and fungi. Overall, conventional nitrogen application resulted in higher diversity of rhizosphere bacterial communities compared to other nitrogen application rates.

Summary: This study found that fertilization and rhizosphere selection have different effects on soil nitrogen cycling and microbiome in the Loess Plateau of China's semiarid area. Organic fertilization simplifies bacterial networks but increases the complexity and stability of fungal networks. Rhizosphere selection has a stronger impact on soil nitrogen cycling, and certain key gene families contribute greatly to crop yield.

Summary: This research investigates the impacts of zinc oxide nanoparticles (ZnO NPs) and zinc sulfide nanoparticles (ZnS NPs) on sedimentary microbial communities and nitrogen cycling in freshwater systems. The study finds that ZnO NPs and ZnS NPs significantly alter microbial communities and nitrogen cycling processes in sediments. The impacts differ between short-term and long-term exposure, with ZnO NPs causing larger structural shifts in microbial communities. The research also reveals that the impacts vary in different lake-derived microcosms and are correlated with microbial community structure. Overall, the study highlights the significant importance of pristine or sulfidized ZnO NPs in freshwater systems.

Summary: Integrating diverse cover crops into dryland crop-fallow rotations can enhance soil nutrient and water retention, suppress soil-borne pests, and improve soil health. The effects on soil nematode communities are modulated by the functional type and mixture composition of the cover crops. Selecting cover crops with appropriate traits can improve soil health through suppression of plant-parasitic nematodes, promotion of free-living nematodes, and enhancement of soil food web complexity.

Summary: In extreme desert environments, black septate endophytes (DSE) can benefit the relict plant Gymnocarpos przewalskii by assisting it to survive and maintain ecosystem stability. The colonization of DSE in the roots of G. przewalskii varies significantly with seasons and sites, with soil properties being a major factor affecting the composition of DSE. Additionally, the functional metabolite composition of DSE strains varies greatly with different drought levels and isolates, indicating the potential complementarity between different strains in helping hosts cope with drought stress.
