Apple replant disease(ARD)is a common soil-borne disease,and has a negative impact on the growth and yield of apple trees(Jiang et al.,2023).Due to the prevalence of pathogenic Fusarium spp.,the resulting microbial community shift in the rhizosphere soil has been the primary cause of ARD in major apple-producing regions along the Bohai Gulf(Wang et al.,2018).Chemical fumigation is gradually eliminated because of its environmental ***,it is crucial to find sustainable,eco-friendly,and effective biological measures to alleviate ARD(Wang et al.,2022).Since the discovery of antagonistic and plant growthpromoting bacteria(such as Bacillus spp.),their solid microbial fertilizers have been demonstrated to have effective biocontrol properties(Shahid et al.,2021).In view of the variety of natural antifungal compounds of Bacillus spp.(Jasim et al.,2016;Ismaila et al.,2023),there were few reports on applying sterile supernatant of Bacillus *** prevent ARD.

The Van Allen radiation belts are doughnut-shaped zones surrounding Earth, filled with highly energetic charged particles whose sources or loss mechanisms have been investigated for decades. As for the inner belt, cosmic ray albedo neutron decay(CRAND),radial diffusion, and local acceleration have been considered principal sources of electrons, whereas protons are predominantly from CRAND and solar protons. In this article, lightning-induced neutrons from Earth's upper atmosphere are suggested as a possible source of protons and electrons in the inner radiation belt. These terrestrial neutrons can contribute to the inner belt population by undergoing nuclear decay. Several approaches are proposed and discussed to evaluate the potential contribution of lightning-induced neutrons to the inner belt, including magnitude estimation, Monte Carlo simulations, and in situ observations. This article discusses some avenues of further study to determine the contribution of lightning-induced neutrons to the inner radiation belt.

Small RNAs(sRNAs) are a class of molecules capable of perceiving environmental changes and exerting posttranscriptional regulation over target gene expression,thereby influencing bacterial virulence and host immune responses. Pseudomonas plecoglossicida is a pathogenic bacterium that poses a significant threat to aquatic animal health. However, the regulatory mechanisms of sRNAs in P. plecoglossicida remain unclear. This study focused on sRNA113, previously identified as a potential regulator of the fliP gene, a key component of the lateral flagellar type III secretion system. To investigate the effects of sRNA113on P. plecoglossicida virulence, as well as its role in regulating pathogenic processes and host immune responses, mutant strains lacking this sRNA were generated and analyzed. Deletion of sRNA113 resulted in the up-regulation of lateral flagellar type III secretion system-related genes in P. plecoglossicida, which enhanced bacterial swarming motility, biofilm formation,and chemotaxis ability in vitro. In vivo infection experiments with pearl gentian grouper revealed that sRNA113 deletion enhanced the pathogenicity of ***. This heightened virulence was attributed to the up-regulation of genes associated with the lateral flagellar type III secretion system, resulting in higher bacterial loads within host tissues. This amplification of pathogenic activity intensified tissue damage, disrupted immune responses, and impaired the ability of the host to clear infection, ultimately leading to mortality. These findings underscore the critical role of sRNA113 in regulating the virulence of P. plecoglossicida and its interaction with host immune defenses. This study provides a foundation for further exploration of sRNAmediated mechanisms in bacterial pathogenesis and hostpathogen interactions, contributing to a deeper understanding of virulence regulation and immune evasion in aquatic pathogens.

Despite the availability of effective antibacterial drugs, the increasing prevalence of antibiotic-resistant bacteria is primarily attributed to their excessive and inappropriate utilization. Antimicrobial resistance (AMR) represents one of the most concerning global health and development threats [1]. Thereby, the continuous escalation in AMR necessitates urgent advancements in novel antibacterial strategies. The MraY enzyme, which plays a pivotal role in synthesizing bacterial cell wall-composing polysaccharides, holds significant potential as a target for antibacterial agents [2]. However, its conformational dynamics have presented substantial challenges in developing MraY-targeting inhibitors.

With the rapid development of the world economy, complex air pollution has increasingly become a serious threat; for example, with haze events occurring frequently in various regions of the globe. Recent evidence has indicated that secondary aerosols play an important role in haze formation, and that heterogeneous processes are among the main forces driving their explosive growth. In this regard, this paper reviews recent advances in the understanding of the impact of heterogeneous processes on haze chemistry, including the impact on NO2chemistry, marine aerosols, and the hygroscopicity and optical properties of atmospheric aerosols. It is distinguished from past reviews on this topic by focusing mainly on new insights from the past five years. We summarize the main findings of the impacts of heterogeneous processes on NO2chemistry, marine aerosols, and the physicochemical properties of atmospheric aerosols, and propose several future research directions.
