fungi in temperate grasslands

The Transitional 2 area appeared to have a variable soil fungal community exhibiting some degree of dominance. Spore colour is given but the spore size, shape or ornamentation is sadly missing with any other microscopy. Ungulate and topographic control of arbuscular mycorrhizal fungal spore community composition in a temperate grassland. (, von Wintzingerode H S.C D.A Culture-based analyses, such as plate counts, selective enrichment, or baiting (for in situ isolation of fungi), only profile the limited culturable proportion of the fungal community, whereas the other techniques provide little insight into fungal community structure. Relative abundance (%) of fungal TRFs in soil at positions across a transect between U4a and MG7b grasslands. E D Concentrations of ergosterol in samples were quantified by comparison with standard ergosterol solutions. Polymerisation was achieved by addition of ammonium persulphate (0.10% v/v) and TEMED (N,N,N′,N′-tetra-methyl-ethylene diamine, 0.05% v/v). Leeflang Floristic analysis of the climax grasslands indicated Agrostis capillaris, Galium saxatile, Potentilla erecta and Rhytidiadelphus squarrosus occurring at 100% frequency and Festuca ovina at 80% in the Nardo-Galion (U4a) grassland, with L. perenne, Poa trivialis and T. repens all occurring at 100% frequency in the Lolio-Plantaginion (MG7b) grassland. Numbers of DGGE bands were found to increase across the transect with a total number of identifiable bands ranging from 13 detected from the U4a community and 14, 18 and 15 detected in soil from the Transitional 1, Transitional 2 and MG7b areas respectively. Multivariate ANOVA followed by Bonferroni's t-test (P≤0.05 probability level) was used to determine significant differences in the presence of individual TRFs between positions across the transect. This revealed that three TRFs (578, 130 and 634) did not correspond to any sequences present in the database; TRF568 matched to two species of Kionochaeta (Sordariales); TRF573 matched to Kluyveromyces lactis; TRF565 matched to 23 members of the Basidiomycota (6% Ceratobasidiales/Cantharellales, 20% Stereales, 27% Hymenomycetidae and 47% Agaricales); and TRF563 also matched 23 species, mostly members of the Basidiomycota (6% Hymenomycetidae, 6% Agaricales, 78% Tremellales) but also matching 10% Taphrinales (Ascomycota). TRFLP has been shown to typically distinguish a greater proportion of ribotypes from environmental samples [40]. H P Although fungal biomass was reduced towards MG7b, both TRFLP and DGGE data indicated that position within the transect (and hence the environmental parameters operating at that position) did not reduce fungal ribotype number (diversity). Kjoller Liu The primer sequence and the MspI recognition sequence were successfully pattern-matched to 1477 sequences in the database. Darbysh. (, Brodie In: Nordic Journal of Botany, Vol. What are some protists and fungi in Temperate grasslands? M Briefly, at one part of the site an area of Lolio-Plantaginion grassland (MG7b type within the UK National Vegetation Classification [1]) had been enclosed, this was a product of ploughing and reseeding in 1993. Some types of fungi make the plants more resistant to insect and microbial attacks. Soil from the Transitional 1 area also contained significantly (P<0.05) higher ergosterol concentrations than MG7b. TRF568 was present in high abundance in all positions across the transect, whilst TRF586 increased across the transect. CLM includes long-form articles, events listings, publication reviews, T Garchow Proximity matrix based on Jaccard measurements of fungal ribotype similarity in soil at positions across a transect between U4a and MG7b grasslands as measured from 18S rDNA TRFs and DGGE bands (1.0 indicates complete similarity). P.J. (, Moeseneder The relationships between fungal … (, Ruzicka The U4a soil community appeared to have many more co-dominant members than the improved soil communities. M.M The forward primer nu-SSU-0817-5′ was labelled with fluorescent dye D4 (Beckman Coulter Inc., CA, USA). A number of techniques have been used to assess soil fungal communities including culture-based approaches, direct microscopy of soil hyphae [10,11], fatty acid analysis [12,13] and membrane sterol quantification [14,15]. Molecular techniques based upon the analysis of rRNA genes are now widely used for the assessment of bacterial and fungal community structure in soils (e.g. van Elsas Extraction efficiency of ergosterol from soil in these experiments was estimated at 85±3.5%. In acidic upland grasslands, fungi have been shown to be major components of soil microbial biomass [4], contributing significantly to nutrient and organic turnover processes including proteolysis, phosphorus mobilisation and translocation [7–9]. HPLC analysis was carried out using a Waters Sugar-Analyser I HPLC system with a Partisil ODS 10 HPLC column (22 cm in length, 4.6 mm in diameter – Hichrom, Reading, UK) with a methanol mobile phase at 1 ml min−1. (, Ranjard Department of Industrial Microbiology, University College Dublin, Belfield, Dublin 4, Ireland. ), which is a common forage grass in the United States, Australia, New Zealand, and temperate European grasslands. Douglas A. Frank. Changes in soil ergosterol concentrations across the transect between U4a and MG7b grassland types indicated that levels of active fungal biomass in improved soils were reduced by around 50%. Increased soil pH has been shown to influence levels of fungal biomass although varied responses have been reported [34,35]; likewise nitrogen applications have been implicated in both increased and decreased fungal biomass [5,36,37]. Low similarity values applied to all pairwise comparisons. Nevertheless, while having no effect on total ribotype number, there were obvious changes in ribotype composition, with the appearance and disappearance of ribotypes across the transect. scientific literature through a combination of long-form articles, regular columns and reports, Z Davies Grassland in all its form supports a vast variety of mammals, reptiles, birds, and insects. G.J R.D S When the seven most abundant TRFs from U4a soil were compared to the database three TRFs (578, 130 and 634) did not correspond to any sequences present. Nazaret The results of Jaccard similarity measurements are presented as a proximity matrix. Furthermore, a general problem with PLFAs is that species composition within groups cannot be detected (for example within decomposer fungi, which are all represented by PLFA 18∶2ω6), while different species within a group might differ in their PLFA content , and fungal communities are likely to be impacted by grasslands management . These practices are also known to affect the microbial component of soil communities, with fertiliser or lime applications typically resulting in increased bacterial numbers, decreased fungal biomass, and changes in microbial functional properties [3–6]. Klironomos Stahl I The practices of liming, fertilisation, increased grazing and reseeding lead to diminished floristic diversity, with a shift from semi-natural species-rich grasslands to species-poor plant communities dominated principally by perennial ryegrass (Lolium perenne) and white clover (Trifolium repens).

Clearly these factors will influence the composition and abundance of fungal community members, although it is not possible to single out any one factor as a dominant one from this data. R.D Hans While temperatures are often extreme in some grasslands, the average temperatures are about -20°C to 30°C. Acidic upland grasslands have become increasingly managed in recent years to improve the productivity of areas previously considered rough grazings (low yielding permanent pasture), leading to significant floristic change [1,2]. G.S Arbuscular mycorrhizal is a type of fungi that is found in temperate grasslands. The Eurasian steppe is one of the largest temperate grasslands and play an important role in the global C and N cycles. [27]. E Grasslands receive about 500 to 950 mm of rain per year compared to deserts, which receive less than 300 mm and tropical forests, which receive more than 2,000 mm. Fungal community diversity (Shannon–Weaver index) as estimated from TRFLP profiles was significantly (P<0.05) lower in soil from the Transitional 2 area than in any other position across the transect (Table 1).

Saxman TRFs can potentially be used to indicate phylogenetic associations, which can be used to propose putative species identity. Jarvis Part of this work was supported by the Enterprise Ireland Basic Research Grant Programme. (, Kaufman Forney The composition of fungal species present in a grassland soil may have important implications for plant biodiversity and ecosystem variability [42], while ecosystem stability may be particularly affected if application of inputs to managed pastures is suspended. In this paper, fungal community structure is assessed using community fingerprinting approaches to profile soil taken from a zone of floristic transition (transect), which reflects a change in grassland floral communities from a typical upland acidic system to an agriculturally improved ley community. In principle, combining these parameters builds a view of fungal community structure. A Tanya R. Murray. The Shannon–Weaver diversity index also indicated a change in community diversity based on TRFLP data, although fungal diversity did not decrease with decreasing floristic diversity. M.J (n=9). In each quadrat three randomly selected cores (10 cm diameter) were taken to a depth of 15 cm in September 1998. Hill Eoin Brodie, Suzanne Edwards, Nicholas Clipson, Soil fungal community structure in a temperate upland grassland soil, FEMS Microbiology Ecology, Volume 45, Issue 2, July 2003, Pages 105–114, https://doi.org/10.1016/S0168-6496(03)00126-0. R Boddy Griffith Soil fungal richness increased with plant species richness and mean annual precipitation. (, Smit These findings give new insight into dominant plant species shifts in degraded semiarid grasslands. Bardgett and McAlister [33] found that unimproved upland pastures had higher levels of fungal PLFAs than improved upland pastures. Bardgett The aim of this work was to assess whether reductions in fungal biomass reported as a consequence of agricultural improvement correspond to alterations in fungal community structure. Where C=2.3, N=sum of peak heights in a given TRFLP profile assuming that each peak has a height of 1, and ni=height of TRF i (1), i=number of TRFs in each TRFLP profile. J.R Ascomycota, Basidiomycota and zygomyceteous fungi dominate the temperate grasslands. Fungi create a fruiting body, the part of the mushroom we see aboveground that release spores to reproduce. Glandorf arbuscular mycorrhizal fungi between fertilized and unfertilized grasslands (F 129 = 1.57, P = 0.016; Fig 4). This may reflect the dominance of culturable industrial and medically important species in such databases. Published eight times a year, British Wildlife bridges the gap between popular writing and In fact a single TRF (568) from Transitional 2 soil accounted for almost 40% of the relative abundance in those profiles (mean of three replicates). (, Olsson A constitutive, host-specific symbiosis exists between the aboveground fungal endophyte Epichloë coenophiala (Morgan-Jones & W. Gams) and the cool-season grass tall fescue (Lolium arundinaceum (Schreb.) Sanders A notable component of this zone was a progressive reduction in grassland species number in the order U4a>Transitional 1>Transitional 2>MG7b. Crossref. (, Donnison P.F Selectivity and functional diversity in arbuscular mycorrhizas of co-occurring fungi and plants from a temperate deciduous woodland. (, Haack For example, the ribotype with a TRF length of 578 (TRF578) was the most abundant in U4a soil, but declined very markedly in Transitional 1 and was not detectable thereafter. Similar reductions in fungal biomass have been found in other studies. For example, U4a soil produced six TRFs which accounted for more than 10% of the relative abundance, Transitional 1 produced three TRFs accounting for 10% each while Transitional 2 and MG7b only produced one or two TRFs respectively which accounted for 10% or more of the relative abundance. It describes and illustrates most of the species that are identifable in the feld: some 170 species in all. Gels were electrophoresed for 17 h at 85 V in 1×TAE buffer at a constant temperature of 60°C using a Bio-Rad DGENE® system. One-way analysis of variance (ANOVA) was used to determine significance of differences between ergosterol concentrations, Shannon–Weaver diversity estimates, and equitability of communities in soil at positions across the transect. Herndl Secondly, fragment lengths can potentially be compared with known sequences in a database or clone library (identification of ribotypes); while fragment peak height provides information about the relative abundance of a ribotype within a particular soil sample. S.P © 2003 Federation of European Microbiological Societies. Forney The samples were then centrifuged at 3000×g for 3 min to separate the pentane layer from the soil. Soil physico-chemical properties also changed across this transect with notable increases in soil pH, nitrate, calcium, phosphorus and potassium towards MG7b, while organic matter content and ammonium levels declined (see [25] for full description). W.T This was to ensure that wells to which the DNA samples were to be added would be sufficiently polymerised so no leakage would occur. Such methods provide an overview of fungal community structure but have inherent limitations. E-mail: E-mail address: trmurray@syr.edu Search for more papers by this author. J.S S.C The page count has increased from 336 to 400 pages. G.M A further soil DNA purification step was found to be necessary in most cases and therefore was performed on all samples. These approaches are dependent upon the successful extraction and purification of environmental nucleic acids from soil, together with PCR amplification linked either to a clone sequence-based analysis or a community fingerprinting technique. (, Miller (, Ranjard Measurements based upon the assessment of microbial biomass through quantification of signal molecules such as fatty acids or sterols give a broad-scale view of microbial population structure, but may be limited by the influence of microbial physiological status [15,38] and can only give very superficial diversity estimates. In a grassland biome, some decomposers are earthworms, beetles, flies, and fungi. It is possible that differences in the initial fungal community compositions of soils contribute to these contrasting findings. O 218 124) at an altitude of 300 m above sea level on a peaty podzolic soil formed over granite/quartzite bedrock, with an annual rainfall between 2000 and 2800 mm, and is described in detail elsewhere [25]. The thermocycling conditions were as follows: a hot start at 94°C for 2 min (one cycle); 94°C for 1 min, 56°C for 2 min, 72°C for 1.5 min (45 cycles); 72°C for 5 min (one cycle). Schmidt The question is this: will it be as useful nationally as it is for the Wye Valley? They are commonly found on prairies and decompose grass and leaves. G A zone of floristic transition was evident between the two grassland types based on increased frequency and abundance of Lolio-Plantaginion plant species. D.A Grid Ref. Garrity Lata It is often perceived that high plant diversity should promote a richly diverse microbial community due to the formation of intimate relationships between specific plant species and microorganisms, and conversely low plant diversity should be associated with reduced microbial diversity. We thank the Roche family at Longhill for kind permission to carry out field work on their land, Terry Marsh for providing the 18S rRNA database subset, Martin Moelhoff for assistance with PatScan. I E T.A W.D Google Scholar. Mougel Waxcap grasslands are fragile ecosystems known to contain a high diversity of fungi. This is borne out from comparing proximity matrices generated from TRFLP and DGGE data (Table 3), with similarities between transect positions being much greater for DGGE ribotypes than those for TRFLP. (, Grayston [...] A succinct description is given, often with numerous colour photographs which are mostly of excellent quality. R.D S K PCR products of the correct size were confirmed by agarose gel electrophoresis and subsequently purified using a High Pure™ PCR product purification kit (Roche Diagnostics GmbH, Mannheim, Germany) according to manufacturer's instructions (50 μl final volume). W.J This describes the similarity of each sample pair based only on DGGE bands or TRFs present in one or both communities. Data represent combined values from three subsamples at each position. Conversely, Brodie et al. Edwards British Wildlife is the leading natural history magazine in the UK, providing essential reading (, Bardgett Visual inspection of the list of unique TRFs detected (Table 2) supports this finding. Citing Literature. J J.M After extraction and purification of total DNA from soil, a portion of the eukaryotic 18S small subunit rRNA gene specific to fungi was amplified using primer set nu-SSU-0817-5′ (5′-TTAGCATGGAATAATRRAATAGGA-3′) and nu-SSU-1536-3′ (5′-ATTAGCAATGCYCTATCCCCA-3′) [19]. This reflects the more limited resolution of DGGE in detecting less abundant ribotypes. Transects extended over the field boundary, 7 m into the Nardo-Galion grassland, and 3 m into the Lolio-Plantaginion grassland. [...] This is a well-produced and much-needed guide to grassland fungi that should be useful to beginners as well as to more experienced feld mycologists. (, Maidak Although mean ribotype number as determined from TRFLP data (Table 1) was not significantly different across the transect between U4a and MG7b, Jaccard analysis of both fragment length and DGGE data (Table 3) indicated that the composition of soil fungal communities across the transect was quite different. S A.W Marsh The value of a TRFLP approach is that it may be interpreted on a number of levels. Dunfield During much of the winter, temperatures are low and … P.J Sparling DGGE data and pooled TRFLP data were converted to binary format and compared using the Jaccard coefficient (Sj) [31]. L.M Here, we show that the diversity of putative pathogenic, mycorrhizal, and saprotrophic fungi is a primary regulator of plant-soil feedbacks across a broad range of temperate grassland plant species. book reviews and letters. across the British Isles. J.L Plant growth is possible when temperatures are warm enough and when ample water is available to sustain it, which typically occurs in the spring, summer, and fall. Cloning-based approaches are costly, laborious and generally less suited to the analysis of multiple samples. DGGE profiles of fungal communities in soil at positions across a transect between U4a and MG7b grasslands. The remainder of the extraction process was as per the manufacturer's instructions. F T.G The sites represent a wide range of soil conditions, hydrologic Karlen This step involved adding 0.1 g of polyvinylpolypyrillidone (PVPP) to each 50-μl DNA extract and incubating at 4°C for 1 h followed by centrifugation at 14 000 rpm for 2 min. This could be improved through the use of more than one restriction enzyme for the analyses, or through identification of TRFs within clone libraries generated from rDNA sequences predigestion.
