“…Similar observation was shown in the study of Ma et al (2013), who found that Ascomycota dominated the fungal community during 28 days of straw decomposition in arable soil. Ascomycota and Basidiomycota represent the main classified fungal decomposers in different soils (Vandenkoornhuyse et al 2002).…”

Purpose Returning crop straw into fields is a typical agricultural practice to resolve an oversupply of straw and improve soil fertility. Soil microorganisms, especially eukaryotic microorganisms, play a critical role in straw decomposition. To date, microbial communities in response to straw amendment at different moisture levels in Chinese fluvo-aquic soil are poorly understood. The aim of this study was to explore the effects of straw amendment and moisture on microbial communities in Chinese fluvo-aquic soil. Materials and methods Two soils (one was applied with organic manure, and the other was not applied with any fertilizer) from a long-term field experiment in the North China Plain were collected. Soils with and without straw amendment at 25 and 55 % of the average water-holding capacities of the two soils were incubated at 25°C for 80 days. All treatments were sampled 20 and 80 days after the start of incubation. Microbial biomass and community structure were analyzed by phospholipid fatty acids (PLFA) assay, and the eukaryotic diversity and community composition were assessed via barcoded pyrosequencing of the 18S ribosomal RNA (rRNA) gene amplicons.Results and discussion PLFA analysis showed that straw amendment increased the biomass of Gram-positive bacteria, Gram-negative bacteria, actinobacteria, and fungi and shifted microbial community structure. The varied straw availability resulted in a large variation in microbial community structure. In the presence of straw, actinobacterial and fungal biomass both decreased under high moisture content. 18S rRNA gene pyrosequencing indicated that straw amendment decreased eukaryotic diversity and richness and probably restructured the eukaryotic community. Under identical moisture content, long-term organic manure-fertilized soil had higher eukaryotic diversity and richness than the unfertilized soil. In the amended soils under high moisture content, the relative abundance of dominant fungal taxa (Dikarya subkingdom, Ascomycota phylum, and Pezizomycotina subphylum) decreased. Conclusions Straw amendment increases microbial biomass, shifts microbial community structure, and decreases eukaryotic diversity and richness. High moisture content probably has a negative effect on fungal growth in the amended soils. In conclusion, microbial communities in Chinese fluvo-aquic soil are significantly affected by straw amendment at different moisture levels.

“…Besides, many members of Basidiomycota and Ascomycota are saprotrophic fungi, which are more able to degrade lignocellulose organic matter (Osono & Takeda, ; Yelle, Ralph, Lu, & Hammel, ), such as straw, litter, and wood (Van der Wal et al, ). The forest soils were enriched with lignin content relative to other soils (Ma et al, ). Therefore, the total relative proportions of Ascomycota and Basidiomycota in the forest soils were distinctly higher than those in other soils (Figure S3b).…”

Effect of land use on the composition of bacterial and fungal communities in saline–sodic soils

Considerable attention has been paid to the establishment of an appropriate land use type for the reclamation of saline–sodic soils. The microbial community structures under various land use types, however, remain elusive in the western Songnen Plain of China. The aim of this study was to explore changes of bacterial and fungal abundance and community patterns under six various land use types: (a) forest, (b) sorghum, (c) paddy, (d) wetland, (e) wasteland, and (f) meadow, with a–c considered to be 'managed systems' and d–f to be 'unmanaged systems.' High‐throughput sequencing and quantitative polymerase chain reaction of bacterial 16S rRNA and fungal internal transcribed spacer rRNA genes were applied to investigate the microbial composition. The results indicated that bacterial abundance ranged from a minimum of 3.40 × 107 copies g−1 dry‐weight soil (d.w.s.) in sorghum to a maximum of 1.03 × 109 copies g−1 d.w.s. in wetland and fungal abundance ranging from 7.11 × 105 to 5.83 × 106 copies g−1 d.w.s. with lowest measured in wasteland and highest in forest, respectively. The abundance and community structures of both bacteria and fungi were similar in paddy and wetland soils, suggesting drying–rewetting alternations played a much greater role in shifting soil microbial communities than other agronomic measures (e.g., fertilization and tillage). The redundancy analysis combined with phylogenetic investigation of communities by reconstruction of the unobserved states and FUNGuild analyses indicated that bacteria predominated in nutrient cycling, whereas Ascomycota and Basidiomycota fungi were largely responsible for the restoration of aggregate stability in saline–sodic soils.

“…Previous work in forest soils has determined that microbial assemblages change (Baldrian et al ., ) and become less diverse (Jumpponen et al ., ) with soil depth and that Ascomycota dominate the upper‐most (0.5–1 cm) litter layers, whereas ectomycorrhizal Basidiomycota, including agarics, are more abundant in the deeper soil layers (Buée et al ., ; Voříšková et al ., ). Similarly, other researchers have determined that Ascomycota flourish in response to straw additions to soil (Ma et al ., ), during the early phase of litter decomposition in soils (Kubartová et al ., ; Voříšková and Baldrian, ) or on living leaves of Quercus macrocarpa (Jumpponen and Jones, ). Because the fungal community in the near‐pristine DBC was dominated (84%) by Basidiomycota (particularly Agaricomycetes), it more closely mirrored fungal communities that are typical of deeper soil layers.…”

Little is known about the fungal role in biogeochemical cycling in oligotrophic ecosystems. This study compared fungal communities and assessed the role of exogenous carbon on microbial community structure and function in two southern Appalachian caves: an anthropogenically impacted cave and a near-pristine cave. Due to carbon input from shallow soils, the anthropogenically impacted cave had an order of magnitude greater fungal and bacterial quantitative-polymerase chain reaction (qPCR) gene copy numbers, had significantly greater community diversity, and was dominated by ascomycotal phylotypes common in early phase, labile organic matter decomposition. Fungal assemblages in the near-pristine cave samples were dominated by Basidiomycota typically found in deeper soils (and/or in late phase, recalcitrant organic matter decomposition), suggesting more oligotrophic conditions. In situ carbon and manganese (II) [Mn(II)] addition over 10 weeks resulted in growth of fungal mycelia followed by increased Mn(II) oxidation. A before/after comparison of the fungal communities indicated that this enrichment increased the quantity of fungal and bacterial cells, yet decreased overall fungal diversity. Anthropogenic carbon sources can therefore dramatically influence the diversity and quantity of fungi, impact microbial community function, and stimulate Mn(II) oxidation, resulting in a cascade of changes that can strongly influence nutrient and trace element biogeochemical cycles in karst aquifers.
