Background: Key members of the rhizomicrobiome, plant root exudates, and pathogen inhibition are important for the immune system functions of disease-suppressive soils, and a "cry for help" mechanism is proposed to describe this immune response process. However, there is still a gap in the understanding of rhizomicrobiome functional genes that are regulated by plants; to date, most studies have shown that the "cry for help" process is mediated by root exudates. The cross-talk between eukaryotes and prokaryotes through microRNAs (miRNAs) represents a new route for research on host and microbe interactions.

Microalgae-based wastewater treatment integrates wastewater purification with bioenergy recovery, aligning with the principles of the circular bioeconomy. However, the limited utilization of the solar spectrum by microalgae and light attenuation caused by wastewater turbidity constrain microalgal growth. To address these challenges, this study synthesized nitrogen-doped carbon quantum dots (N-CQDs) with down-conversion properties that convert UV light (∼380 nm) from the solar spectrum into blue light (450-475 nm) useable by microalgae, thereby enhancing their solar energy utilization efficiency.

The complexity of soil microplastic pollution has driven deeper exploration of waste management strategies to evaluate environmental impact. This study introduced oversized microplastics (OMPs, 1-5 mm) during membrane composting to produce organic fertilizers, and conducted a 2 × 2 pot experiment: exogenous OMPs were added when normal fertilizer (no OMPs intervention) was applied, while artificial removal of OMPs was implemented when contaminated fertilizer (with OMPs) was used. The study assessed the effects of these management strategies on lettuce growth, soil environments, and potential biological safety risks related to the spread and expression of high-risk antibiotic resistance genes (ARGs) in humans.

Two-dimensional (2D) transition metals enable the elimination of metal-induced gap states and Fermi-level pinning in field-effect transistors (FETs), offering an advantage over conventional metal contacts. However, transition metal substrates typically exhibit nonoriented behaviors, leading to the inability to achieve monolingual responses with P- or N-type semiconductors. Here we devise symmetry engineering in an oxidized architectural MXene, termed OXene, which implements the exploiting and coupling of additional out-of-plane electron conduction and built-in polar structures.

The black soldier fly (BSF, Hermetia illucens) is a resource insect that can utilize livestock and poultry feces. However, BSFs may also increase the risk of transmission of antibiotic resistance genes (AGRs) that are widespread in livestock and poultry farm environments. Therefore, we aimed to evaluate the biosecurity risks of different BSF treatments in the laying chicken food chain using the "chicken manure-BSF-laying hens" model.

The different forms and properties of microplastics (MPs) have different effects on the elemental cycles in soil ecosystems, and this is further complicated when the soil contains antibiotics; meanwhile, oversized microplastic (OMP) in soil is always ignored in studies of environmental behavior. In the context of antibiotic action, the effects of OMP on soil carbon (C) and nitrogen (N) cycling have rarely been explored. In this study, we created four types of oversized microplastic (thick fibers, thin fibers, large debris, and small debris) composite doxycycline (DOX) contamination layers (5-10 cm) in sandy loam, hoping to reveal the effects on soil C and N cycling and potential microbial mechanisms when exposed to the combination of manure-borne DOX and different types of OMP from the perspective of metagenomics in the longitudinal soil layer (0-30 cm).

Manure treatment with black soldier fly larvae (BSFL) and BSFL frass application in crop land is a sustainable strategy; however, whether residual antibiotic resistance genes (ARGs) and their transmission risk are related to the manure BSFL treatment process is still unknown. In this paper, the effect of BSFL addition density on residual tetracycline resistance genes (TRGs) and transmission from frass to pakchoi was determined. The results showed that BSFL frass can provide sufficient nutrients for growth, improve the economic value of pakchoi, and reduce the risk of transmission of TRGs in chicken manure regardless of BSFL density.
