Two important functions they perform are facilitating nutrient uptake in host plants and protecting plants from biotic stress, among other functions. AM fungal taxa vary in how capably they perform these functions and can also respond differently to environmental selection. Therefore, there is a need to better understand how particular environmental variables might alter the response of AM fungal communities. Here, we analysed data from a DNA-based survey of fungal communities in soils collected throughout Australia to observe relationships among soil nitrogen and phosphorus availability and the abundance of two AM fungal taxa that reportedly vary in function – the Gigasporaceae (putatively more important for nutrient uptake) and Glomeraceae (putatively more important for biotic stress). Relationships were assessed in three vegetation types – grasslands, forests and woodlands – to assess whether associations with soil nutrition varied depending on carbon availability for AM fungi. Fungi from the Gigasporaceae decreased in frequency as available phosphorus increased, while those from the Glomeraceae increased or were unresponsive as available phosphorus increased. Similar patterns were observed for nitrate availability, although only in woodlands. These patterns are consistent with expectations that AM fungi from the Gigasporaceae, in general, are better suited to alleviate nutrient limitation in hosts as soil chemical fertility decreases. This knowledge may aid in implementing optimal strategies involving AM fungal inoculum best suited to the local conditions of future land management and agricultural projects.</p></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0031405624009053/pdfft?md5=6a8bfda8325e42716bfca31ade938dbe&pid=1-s2.0-S0031405624009053-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139556465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the function of these bacterial communities in healthy potato plants is still largely unknown. Here, we aimed to describe the structure and composition of tuberosphere bacteriomes and its capability to make organosulfur plant available using the rhizosphere and bulk soil bacterial community characteristics as a reference. Rhizosphere, tuberosphere and bulk soil was collected from two field grown potato varieties. Bacterial communities were characterized by 16S rRNA gene amplicon sequencing. Bacterial organosulfur mobilization indicators were evaluated with cultivation dependent and independent methods and were correlated (Spearman) with the relative abundance of bacterial families. The structure of tuberosphere bacterial communities either overlapped with the bulk soil or had similarities with the rhizosphere. Relative abundance of specific bacterial families were distinct between bulk soil, tuberosphere and rhizosphere. Tuberospheres had a tendency for higher arylsulfonate utilization compared to bulk soil. The families <em>Sphingomonadaceae, Sphingobacteriaceae</em> and <em>Rhizobiaceae</em> which presented a decline in their relative abundances from the rhizosphere to tuberosphere and bulk soil had positive correlations with organosulfur mobilizing indicators. Potato variety and soil characteristics played a role in structuring the tuberosphere bacterial communities. Tuberospheres represent an environment in-between bulk soil and rhizosphere indicative from the intermediate relative abundances of specific bacterial families. A moderately higher bacterial organosulfur mobilization activity in tuberospheres suggests that this microbial function may serve specific biological roles for potato tubers.</p></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0031405624009065/pdfft?md5=f58313b2f1df9faee4bf76c177eb9d52&pid=1-s2.0-S0031405624009065-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139556321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
