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":"103 ","pages":"Article 150934"},"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":"103 ","pages":"Article 150935"},"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}

While temperature and soil moisture are thought to influence litter decomposition, elucidating consistent soil process responses to observed or predicted shifts in climate have proven difficult to evidence. Here we investigated how aspect (i.e., north-south orientation), a natural model for variation in soil temperature, influenced soil physico-chemical conditions and decomposition of two standardised litter types (Green tea and Rooibos teabags) in Pole-facing (PF) and Equator-facing (EF) roadside verges spanning a 3000 km and 27° latitudinal gradient across Europe. Despite average daily temperatures being 1.5 - 3.0 °C warmer on EF than PF slopes, there were only minor region-specific differences in initial soil physico-chemical conditions and short-term variation in litter decomposition (i.e., litter mass loss was higher in EF-verges for the first month of deployment only) associated with aspect. We conclude that previously observed differences in soil environments and the decomposition process associated with slope orientation, is largely litter or environment specific, although medium-term soil-decomposition in semi-natural grassland ecosystems may also be insensitive to the magnitude of temperature variation within the range predicted by the IPCC SSP1–2.6 emissions scenario. Nonetheless, consistent average and extreme temperature differences between adjacent PF- and EF-aspects along roadside verges provides a model system to explore exactly how resilient the soil environment and the micro-organisms responsible for decomposition, are to temperature variation.</p></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":"102 ","pages":"Article 150927"},"PeriodicalIF":2.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0031405623079957/pdfft?md5=14fdbffdaaadd252595cd7678cbe9ef2&pid=1-s2.0-S0031405623079957-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139462049","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}
