Non-degradable toxic metals (heavy metals), pose a significant health risk due to their persistence in the environment. Soil washing with EDTA (ethylenediaminetetraacetic acid) has been shown to remove toxic metals (Pb, Zn, Cd), but this process can also have a significant impact on soil microbial diversity. In this study, we investigated, using molecular methods (18S rRNA amplicon sequencing), the development of the arbuscular mycorrhizal (AM) fungal communities in the roots of Lolium perenne after a soil remediation treatment with EDTA. Plants were grown on two soil types (calcareous and acidic), in remediated and control (unremediated, polluted) soils, and with or without the addition of a local environmental inoculant (grassland soil and roots). The addition of the inoculant increased the richness and evenness of AM fungi, and reduced the compositional dissimilarity of communities between remediated and unremediated soils. Disturbance from the remediation process and inoculation, lead to a shift in the identity of dominant taxa reflecting different traits among the AM fungi. This suggested two main mechanisms behind community development in remediated soils, i.e. priority effects and competitive exclusion among dominant taxa. These findings emphasise the importance of nature-based solutions (indigenous environmental inoculants) and AM fungi for sustainable soil management practices. This is particularly important for restoring soil biodiversity in sites that have been exposed to multiple disturbances, which may include contaminated sites and soil remediation, as well as conventional agricultural systems, and urban soils.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"36 3","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This holobiont encompasses not only roots and rhizosphere but also interfaces expanded by slender AM fungal hyphae. Our understanding of the microbiomes across these interconnected interfaces remains limited and fragmented. We used a split-root microcosm to inoculate the same maize root system with three AM fungal species, establishing a simplified holobiont. Amplicon sequencing, Biolog-ECO plates, and 13CO₂ labelling revealed the bacterial diversity and community-level physiological profiles (CLPPs). Bacterial communities colonizing non-mycorrhizal roots, mycorrhizal roots, and hyphae exhibited distinct structures and CLPPs. AM fungal species significantly influenced these bacterial communities, particularly in the mycorrhizosphere and hyphosphere, where notable changes occurred in key nutrient-cycling groups, such as phosphate solubilizers and nitrogen fixers. The diversity of the hyphosphere microbiome was closely aligned with fungal phylogeny. Additionally, a stable core microbiome persisted across all interfaces within the plant-AM fungi-bacterial holobiont, with key taxa such as Pseudomonas and Bacillus harboring the P-mobilizing genes encoding quinoprotein glucose dehydrogenase (gcd) and β-propeller phytase (bpp), highlighting their functional importance in nutrient cycling. Our study provides a comprehensive and precise hyphal-scale characterization of microbial communities across key interfaces, offering detailed insights into plant-microbial dynamics driving nutrient cycling and ecosystem functioning.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"36 3","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147840291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, we inoculated two commercial rootstocks (Schwarzmann and 5 C) with AMF communities recovered from different rootstocks from one site to determine effects on plant growth parameters and physiological responses. A glasshouse experiment using a 'home' and 'away' approach was designed to examine the interaction between rootstock variety and different AMF communities, including those from their own ('home') and other rootstocks' rhizosphere soils ('away'). Our results showed that rootstocks grown in their 'home' AMF communities exhibited greater above and below ground biomass compared to 'away' AMF communities, highlighting rootstock specificity in selecting AMF communities. AMF communities increased chlorophyll content and nutrient uptake (copper, boron) in grapevine leaves, where AMF communities dominated by Funneliformis sp., Ambispora sp. followed by Glomus spp. were associated with enhanced grapevine growth. This study enhances our understanding of community-level AMF-grapevine interactions and highlight the ecosystem services these fungi provide. Future research is needed using grafted plants to evaluate their response with different scions following AMF inoculation and to assess the effects of these AMF communities on berry biochemical composition.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"36 3","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147840251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study presented herein elucidates the organization and structure of the mating type (MAT) locus in this species and the spatio-temporal dynamics of T. claveryi strains in Helianthemum almeriense mycorrhizal plants and soil from nursery to field. MAT genes are the master loci controlling sexual reproduction and development in fungi. Our findings demonstrate that T. claveryi is a haploid and heterothallic species as its strains harbor and express either TcMAT1-1-1 or TcMAT1-2-1 genes as revealed by genome sequencing and RNAseq analyses. DNA-binding motifs located in their respective promoter regions appear to play a major role in the regulation of reproductive processes. The α-box and HMG-box domains are highly conserved along the Pezizomycetes and their strong structural similarity despite its poor sequence similarity supports a common evolutionary origin. Moreover, we set out a PCR-based approach to monitor the dynamics of T. claveryi strains of opposite mating type on mycorrhizal plants and soil. T. claveryi mycorrhizal plants at the nursery stage presented strains of both mating types, whereas a notable dominance of strains with the TcMAT1-1-1 gene was observed in field stage. Altogether, this research provides insights about genetic regulation and evolution of the MAT locus within the Pezizomycetes, and the reproductive biology of this important desert truffle, along with reliable markers to track the spatio-temporal distribution of strains of opposite mating types.","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"36 3","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147840327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
