However, the impact of AMF on the rhizosphere bacterial community of tobacco under conditions of low nutrient availability remains unclear. This study investigated the influence of inoculating Claroideoglomus etunicatum on the tobacco rhizosphere bacterial community and the microbial mechanisms by which AMF enhanced plants antioxidant capacity, employing Illumina MiSeq high-throughput sequencing. The findings indicated that AMF significantly increased both the aboveground and belowground fresh weight, as well as the plant height of tobacco. AMF inoculation led to elevated activities of catalase (CAT) and superoxide dismutase (SOD), a reduction in malondialdehyde (MDA) content, and an overall enhancement of the plants antioxidant capacity. Phylogenetic analysis demonstrated that AMF modified the bacterial community structure and significantly enriched beneficial rhizosphere bacteria, predominantly from the phyla Proteobacteria, Chloroflexi, Actinobacteriota, and Myxococcota, thereby facilitating tobacco growth. The network analysis revealed that the incorporation of arbuscular mycorrhizal fungi (AMF) contributed to increased stability within the bacterial community, enriched species diversity, and more intricate ecological networks. AMF enhanced interactions and positive correlations among bacterial species, indicating that heightened microbial synergy is associated with improved symbiotic relationships. Furthermore, the structural equation model demonstrated that AMF bolstered the plants antioxidant capacity by modulating the rhizosphere bacterial community. This study elucidates the impact of AMF on the tobacco rhizosphere bacterial community, providing a theoretical basis for promoting tobacco growth.</p>","PeriodicalId":519913,"journal":{"name":"Advanced biotechnology","volume":"3 3","pages":"22"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12227407/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144562525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the differences in diversity, community structure, and functions of abundant and rare taxa in the rhizosphere microbiome of the same plant in different environments remain unclear. This study focuses on the rhizosphere microbial communities of Artemisia desertorum, a quintessential desert sand-stabilizing plant, investigating the diversity patterns and assembly processes of rare and abundant taxa across four Chinese deserts: Mu Us, Kubuqi, Tengger, and Ulan Buh. The results show that climatic factors, especially aridity and mean annual precipitation (MAP), significantly influence bacterial community composition and microbial network complexity. The interactions between rare and non-rare taxa are non-random, forming a modular network in which rare taxa serve as central nodes, and their loss could destabilize the network. Rare taxa are primarily shaped by heterogeneous selection, whereas abundant taxa are mainly influenced by dispersal limitation. Functionally, abundant taxa exhibit higher metabolic potential, whereas rare taxa are more involved in processes such as cell motility, indicating distinct ecological roles. These results provide new insights into the ecological functions of rare and abundant taxa in desert rhizosphere communities and highlight the importance of microbial management for desert plant health.</p>","PeriodicalId":519913,"journal":{"name":"Advanced biotechnology","volume":"3 3","pages":"21"},"PeriodicalIF":0.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12229302/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144556418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current treatments primarily focus on alleviating individual symptoms, lacking long-term therapeutic strategies that target the disease's endotypes. In this study, we found that Yinling Qushi Granule (YLQSG), a formulated prescription for treating Dampness Syndrome (DS) in Traditional Chinese Medicine (TCM), effectively attenuated hypertension associated with MetS. After 12 weeks of YLQSG treatment, MetS patients showed significant reduction in systolic and diastolic blood pressure, body mass index (BMI) and glycated hemoglobin (HbA1c). Chemical analysis has identified a total of 96 components of YLQSG, alongside with 27 serum absorbed prototypes and 13 metabolites. In vivo metabolic profiling revealed critical Phase I metabolism including dehydration, demethylation, and oxidation. By integrating network pharmacology and molecular docking, we proposed 11 triterpenoids from the sovereign herb Poria cocos (Schw.) Wolf as active constituents of YLQSG. These triterpenoids showed potent binding affinities with AGTR1 and 11β-HSD1, two crucial druggable targets in the renin-angiotensin-aldosterone system. Pharmacokinetics of these 11 lanosterol-type triterpenoids in rat serum indicated their good drug likeness properties. In summary, our findings highlight the potential of YLQSG in treating MetS, particularly hypertension, and identify its active compounds and potential molecular targets, offering a promising alternative strategy for the long-term management of MetS.

Here, combined Pacbio, Hi-C, and Illumina sequencing of the male mandarin fish (Siniperca chuatsi) genome enabled the assembly of a high-quality chromosome-level genome, including highly resolved X and Y chromosome assemblies. Genome wide association study (GWAS) and coverage information analysis revealed a 2.0 Mbp sex determining region (SDR). A Y-specific duplication of the anti-Müllerian hormone (amh) gene, amhy, was identified that encoded a truncated AMH protein. Loss of function and overexpression experiments demonstrated that amhy may act as a male sex-determining gene (SDG). GWAS led to the identification of a common sex chromosome (Chr24) and SDG (amhy) in S. scherzeri, while another sex chromosome (Chr11) was identified in Coreoperca whiteheadi. Interestingly, completely conserved protein coding sequences of amhy were commonly identified in male S. chuatsi, S. scherzeri, and S. knerii.
