Glyptostrobus pensilis is an endangered species belonging to the Cupressaceae family. The comprehensive examination of soil characteristics and rhizosphere microbial communities vital for conservation efforts, as it provides insights into necessary environmental conditions safeguarding ensuring viability rare species. In this study, diversity composition bacterial fungal were compared in roots soils cultivated wild G. Guangxi, China. results revealed that, at phylum level, was significantly enriched with Verrucomicrobiota , Acidobacteriota Glomeromycota Chloroflexi while Planctomycetota Basidiomycota Ascomycota . Symbiotic network analysis indicated that had higher edge values, average degree, clustering coefficient, density, node coefficient. Moreover, functional prediction suggested bacteria showed metabolic activity, fungi primarily acted saprotrophs symbionts. contrast, displayed lower predominantly functioning saprotrophs. linking rhizospheric factors a closer association community, suggesting stronger influence factors. Random Forest (RF) highlighted total phosphorus potassium levels key influencing microbes available crucial those These differences underscore significant strategies adapting different habitats, which may be intricately linked land management practices Among these, are associated microorganisms Therefore, continuous monitoring nutrient availability regular supplementation fertilizers recommended during cultivation ex-situ

Fusarium cross-infection in medicinal herbs alters rhizosphere microbiomes and disrupts mycorrhizal functions under soil physicochemical imbalances

Published: April 3, 2025

Background and Aims Fusarium root rot wilt affect medicinal herbs in Gansu Province, China, despite extended crop rotations. This study investigated the cross-pathogenicity of Fusariumspecies isolated from Angelica sinensis (Danggui), Codonopsis pilosula (Dangshen), Astragalus mongholicus (Huangqi). Methods Of 83 fungal isolates recovered, 69.8% were identified as Fusarium spp., through ITS, TEF1-α, RPB2 sequencing, clustering into Fusarium oxysporum (FOSC, 36.2%), solani (FSSC, 31%), tricinctum (FTSC, 22.4%) species complexes. Representative strains (F. DSH27, F. solaniHQ123, DG105) tested for greenhouse field trials. Rhizosphere microbial dynamics, including bacterial community diversity, functional guilds, soil physicochemical properties, analyzed. Results Fusariumstrains exhibited varying aggressiveness, highest on original hosts, while cross-infective hosts showed less to moderate severity. Infections disrupted rhizosphere networks, increasing pathotrophic dominance over arbuscular mycorrhizal functions. Sequencing reduced operational taxonomic units (OTUs), with distinct infected vs. non-infected rhizospheres. Pathogenic genera positively correlated disease incidence, beneficial Mortierella RB41 negative correlations. Infected soils significant changes total carbon, available phosphorus, manganese, zinc, correlating dynamics Conclusion links cross-infection network disruptions, loss fungi (AMF) functions under altered conditions herbs. These findings uncover systematic species, highlighting need AMF-based strategies integrated management mitigate its impact.

Unraveling the Intricacies of Powdery Mildew: Insights into Colonization, Plant Defense Mechanisms, and Future Strategies

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(8), P. 3513 - 3513

Published: April 9, 2025

Powdery mildew, a debilitating phytopathogen caused by biotrophic fungi within the order Erysiphales, endangers crop yields and global food security. Although traditional approaches have largely emphasized resistant cultivar development chemical control, novel strategies are necessary to counter advent of challenges, such as pathogen adaptation climate change. This review fully discusses three principal areas effector functions, e.g., reactive oxygen species (ROS)-suppressive activity CSEP087, host susceptibility factors, like vesicle trafficking regulated Mildew Locus O (MLO). It also briefly mentions transcriptional regulation resistance genes mediated WRKY75 NAC transcription post-transcriptional via alternative splicing (As). In addition, this discussion intricate interactions among powdery plants, symbiotic microbiomes thereof, highlighting mechanism through which mildew infections disrupt foliar microbiota balance. Lastly, we present new biocontrol approach that entails synergistic microbial consortia, combinations Bacillus Trichoderma, induce plant immunity while minimizing fungicide dependency. Through study combining knowledge molecular pathogenesis with ecological resilience, research offers useful insights towards climate-smart sustainable disease-management in context microbiome engineering.
