Abstract The rhizosphere is the soil region around plant roots hosting a diverse microbial community, influencing nutrient availability and how plants react to extreme conditions. However, our understanding of fungi biodiversity impact environmental variations on this still in its infancy. Our study investigates fungal communities’ diversity functional traits Nothofagus pumilio, one few winters deciduous treeline species world, forming southern South America. At four distinct locations covering 10° latitude, we collected samples at 200 meters below over seasons during single year. We employed ITS metabarcoding elucidate community structures. results reveal that was mainly determined by latitudinal variation, with higher levels warmer lower altitudes. Interestingly, found marked dominance ectomycorrhizal (EcM) treeline, particularly winter. In contrast, saprotrophic were more abundant altitudes, spring summer seasons. These findings highlight temporal spatial dynamics rhizospheric communities their potential roles ecological processes, emphasizing value these as indicators change high-elevation forests.

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

This study aimed to elucidate responses of the bacterial structure and diversity rhizosphere in flowering broomcorn millet after rehydration following drought stress. In this study, varieties 'Hequ red millet' (A1) 'Yanshu No.10' (A2), known for their different tolerance levels, were selected as experimental materials. The plants subjected stress at stage, while normal watering (A1CK A2CK) served control. Soil samples collected 10 days (A11, A21, A1CK1, A2CK1) 20 (A12, A22, A1CK2, A2CK2) rehydration. High-throughput sequencing technology was employed investigate variations community structure, diversity, metabolic functions time points findings indicated that operational taxonomic units (OTUs) bacteria notably influenced by duration treatment, with a significant decrease OTUs observed However, Alpha not significantly impacted mainly composed

Abstract High soil pH severely impacts plant growth and productivity, yet the transcriptomic changes microbial dynamics underlying stress adaptation in garden pea ( Pisum sativum ssp. hortense ) remain unclear. This study demonstrates that high leads to stunted growth, reduced biomass, impaired photosynthesis, nutrient status pea. Further, disruption key nitrogen-fixing bacteria Rhizobium indicum, R. leguminosarum, redzepovicii ), along with downregulation of NifA NifD genes upregulation NifH nodules highlight critical role micronutrient balance legume-microbe symbiosis a compensatory response maintain nitrogen status. RNA-seq analysis revealed extensive transcriptional reprogramming roots, characterized by oxidative (e.g., oxidoreductase glutathione transferase activities, metal ion transporters) related ammonia-lyase activity binding, reflecting broader disruptions homeostasis. KEGG pathway identified enrichment MAPK signaling pathway, likely interacting other pathways associated tolerance, metabolic adjustment, structural reorganization as part adaptive responses pH. Root microbiome showed significant Variovorax, Shinella, Chaetomium , suggesting host-driven recruitment under stress. Stable genera such Pseudomonas, Novosphingobium, Mycobacterium, Herbaspirillum, Paecilomyces displayed resilience conditions, potentially forming core components for In targeted study, inoculation plants an enriched microbiome, particularly C. globosum conditions improved parameters increased abundance Stenotrophomonas Pseudomonas roots.

Soil microorganisms play a crucial role in suppressing soil-borne diseases. Although the composition of microbial communities healthy versus diseased soils is somewhat understood, interplay between interactions and disease incidence remains unclear. This study used 16S rRNA fungal internal transcribed spacer (ITS) sequencing to investigate bacterial community three soil types: forest (Z), from banana plantations (H), (D). Principal coordinate analysis revealed significant differences among structures types. Compared with those soil, diversities significantly decreased soil. Key microorganisms, including bacteria Chloroflexi Pseudonocardia fungi Mortierellomycota Moesziomyces, were increased plantations. Redundancy that total nitrogen available phosphorus primary drivers structure. The neutral model posited assembly predominantly governed by stochastic processes, whereas primarily driven deterministic processes. Furthermore, co-occurrence network proportion positive edges was 5.92 times lower than plantations, its structure sparse simple. In conclusion, reduced within linked epidemiology Fusarium wilt. These findings underscore critical modulating pathogens.
