Soil microbial communities’ assembly is strongly tied to changes in temperature and moisture. Although microbial functional redundancy seems to overcome taxonomical composition changes, the sensitivity and resilience of soil microbial communities from subtropical regions in response to seasonal variations are still poorly understood. Thus, the development of new strategies for biodiversity conservation and sustainable management require a complete understanding of the soil abiotic process involved in the selection of microbial taxa and functions. In this work, we used state of the art molecular methodologies (Next Generation Sequencing) to compare the taxonomic (metataxonomics) and functional (metatranscriptomics) profiles among soil samples from two subtropical natural grasslands located in the Pampa biome, Brazil, in response to short-term seasonal variations. We found consistent effects of season on both microbial community structure and functions, but with the former being more influenced than the latter. These variations were more related to the oscillation in the relative abundances of specific taxa along seasons, rather than extinction and recolonization of taxa along seasons. In conclusion, the most abundant microbial groups and functions were shared between seasons and locations reflecting the existence of a stable taxonomical and functional core microbiota.

Our data suggest that grasslands maintained a stable microbial community membership along the year with oscillation in abundance. Apparently soil microbial taxa are more susceptible to natural climatic disturbances while functions are more stable and change with less intensity along the year. Finally, our data allow us to conclude that the most abundant microbial groups and functions were shared between seasons and locations reflecting the existence of a stable taxonomical and functional core microbiota.

Tuber pseudoexcavatum, Tuber sinoaestivum, and Tuber indicum are the 3 most important truffles growing in southeast China; however, their cultivation is still inefficient owing to the lack of understanding regarding the composition and function of the bacterial and fungal communities from the soils around the fruit bodies and the ectomycorrhiza of these truffles. The aim of this study was to disclose the microbial communities in truffle-producing soils in Huidong County, Sichuan, China, by using barcoded pyrosequencing. Approximately 350 000 quality-controlled sequences were obtained and grouped into 14 025 bacterial operational taxonomic units (OTUs) and 4385 fungal OTUs, which included 29 bacterial and 7 fungal phyla, respectively. The bacterial genus Acidobacterium and fungal genera Modicella, Pseudogymnoascus, and Mortierella were significantly more abundant in the control soils than in the truffle-producing soils (P < 0.05), while the bacterial genus Sphingomonas (Alphaproteobacteria) and arbuscular mycorrhizal fungal genus Glomus were significantly enriched in truffle-producing soil than in the control (P < 0.05), indicating their different roles within truffle grounds. Notably, some nonfungal organisms detected by 18S rDNA pyrosequencing were of high abundance, among which Cercozoa and Ochrophyta were significantly (P < 0.05) more abundant in truffle soils than in control soils, indicating their interactions with truffles.
