Many farmers prefer Switchgrass to other varieties of native grasses because of th… Our results were similar to those of Allison et al. Total lipid biomass (a) and total carbon (b) under different biofuel cropping systems at intensive and extensive sites in Wisconsin and Michigan. Figure S1. No AMF sequences were recovered from soils cultivated with corn in Michigan. Principal components analysis of soil microbial communities from Michigan and Wisconsin intensive sites as evaluated by sequencing of SSU rRNA genes (a), lipid analysis, (b) and NifH sequences (c). Plants host the caterpillars of several skipper species. A Prairie Moon • July 8 Hi Eleni! Switchgrass. A stand of Switchgrass … Switchgrass (Panicum virgatum L.) ist ein Präriegras aus Nordamerika. (2001) do exclude certain groups. It is a natural component of the tall grass prairie that covered most of the Great Plains, as well as the south and eastern United States. The same applies to soils cultivated with corn in Wisconsin. Filter parameters were 0 mismatches to the forward primer, 250 bp length filter, maximum number of N's = 0, and minimum quality score of 20. Others includes sequences from Actinobacteria, Bacteroidetes, Chlorobi, Cyanobacteria, Euryarchaeota, Firmicutes, Fusobacteria, Nitrospirae, Spirochaetes, Synergistetes, and Verrucomicrobia. We sampled from three of the five blocks 2 years after their establishment. The one exception to this generalization was that the lipid data did reveal a crop effect on microbial community structure for the intensive Wisconsin sites. MII = Michigan intensive sites; MIE = Michigan extensive sites; WII = Wisconsin intensive sites; WIE = Wisconsin extensive sites; Co = corn; Mp = mixed grasses; Pr = prairie; Sw = switchgrass. We obtained 124 654 28S rRNA gene sequences for the 16 extensive sites samples retained in the study, with an average read length of 446 bp. 32115 Prairie Lane Winona, MN 55987; 866-417-8156; Email Us; Navigation . 5b). Any queries (other than missing content) should be directed to the corresponding author for the article. switchgrass.lucas@gmail.com 205 South Main Lucas, KS 67648 P.O. The three most abundant identifiable phyla were Ascomycota (67% of total sequences), Basidiomycota (15%), and Chytridiomycota (4%) (Fig. Lipid data were used to estimate microbial biomass, and the following ratios were calculated: fungi/bacteria (F/B), arbuscular mycorrhizal fungi/saprophytic fungi (AMF/SF), and Gram‐positive bacteria/Gram‐negative bacteria (Gm+/Gm−). Additionally, we expected NifH to be less conserved than ribosomal genes, thus giving us a contrast to the highly conserved rRNA gene. Primer sequences were modified by the addition of 454 A or B adapter sequences (lower case). Sequences not identified as fungi by the RDP classifier with the confidence filter set at 0.5 were removed, leaving a total of 119 793 sequences in 632 categories, 94 of which were universal singletons. For the intensive sites, total lipid biomass per treatment did not differ between states (Fig. Community structure of soil fungi in a novel perennial crop monoculture, annual agriculture, and native prairie reconstruction. prairie. Additionally, recently reported results showed that mycorrhizae increased the amount of total N in shoots of switchgrass (Schroeder‐Moreno et al., 2012), indicating that mycorrhizae can also contribute to the increased utilization of this nutrient. Working off-campus? A trade‐off exists between finding primers and conditions that give the best coverage for groups important in the habitat and reliable amplification. The sequences were therefore classified directly using the Ribosomal Database Project (RDP) classifier (Wang et al., 2007) with a manually curated LSU gene training set v1 (Liu et al., 2012) also used in Penton et al. 16S/18S rRNA gene nucleotide sequences were deposited in the European Nucleotide Archive (http://www.ebi.ac.uk/ena) as part of study PRJEB6704 under accession numbers ERR571396 through ERR571438. Prairie Sky. Switchgrass is one of the easiest forms of wildlife cover to plant and if planted correctly, switchgrass can be fully established after only 2 Summers of growth! 5a). Because some sequences were read from each direction, it was not possible to align them. The only exception to this was that the lipid data revealed a crop effect in the richer Wisconsin soil. Chicken Noodle soup has been there through the many days where I needed to feel comfort, warmth and taste something that is familiar. Raw sequences were sorted by bar code, trimmed, filtered to remove sequences of low quality (10% threshold), and aligned. The only significant difference in dispersion (α = 0.05) was for the NifH data by location (Fig. These samples were aligned and clustered into 10 092 clusters (OTUs) at a distance of 3%; 6628 of these clusters were global singletons with Good's estimated sample coverage of 52 to 92% and averaging 85%. In the Southeast, a planting rate of approximately 10 pounds PLS per acre is recommended. Bars represent ±1 standard error. Treatment differences were tested in the same manner as total carbon. In Deutschland ist Switchgrass bisher hauptsächlich als Zierpflanze (Rutenhirse) bekannt. This work was funded by the DOE Great Lakes Bioenergy Research Center (DOE BER Office of Science DE‐FC02‐07ER64494). It’s one of the dominant species of the tallgrass prairie, and can grow up to six feet tall. Principal component analysis (PCA) was used to display distances between sites based on their soil attributes. Michigan and Wisconsin intensive sites differed markedly in their physical and chemical soil attributes (Fig. PCA biplots for the intensive sites based on their soil attributes. MIE = Michigan extensive sites; WIE = Wisconsin extensive sites; Co = corn; Pr = prairie; Sw = switchgrass. MII = Michigan intensive sites; MIE = Michigan extensive sites; WII = Wisconsin intensive sites; WIE = Wisconsin extensive sites; Co = corn; Mp = mixed grasses; Pr = prairie; Sw = switchgrass. Box 61 … FrameBot, included in the Fungene Pipeline (Fish et al., 2013), was used to match representative sequences from each cluster to 187 of 782 unique NifH reference sequences. In particular, corn and to a lesser extent mixed grasses are separated from prairie and switchgrass. The intensive plots were located at the Kellogg Biological Station (KBS) in Michigan and at the Arlington Agricultural Research Station (AARS) in Wisconsin. The thermal cycler protocol was 95 °C for 3 min, 25 cycles of 95 °C for 30 s, 50 °C for 45 s, and 68 °C for 90 s, and a final 10‐min extension at 68 °C. Sorry for the delay due to the 4th of July holiday. In our case, we targeted the nifH gene, which codes for dinitrogenase reductase, a component of nitrogenase, the enzyme responsible for N2 fixation. Additionally, the lipid and NifH data separated the samples by location (Table 2 and Fig. S2). For the NifH data, there was some overlap between the corn and Wisconsin switchgrass samples, but otherwise crops were separated (Fig. Contact Us . 4b,c. Mao et al. Microbial Community Structure and Functional Potential in Cultivated and Native Tallgrass Prairie Soils of the Midwestern United States. [Wilkommen] [Die Pflanze] [Sorten] [Anbau] [Verwertung] [Forschung] [Neuigkeiten] [Kontakt]. We characterized and compared soil microbial communities under restored prairie and three potential cellulosic biomass crops (corn, switchgrass, and mixed prairie grasses) in two spatial experimental designs – side‐by‐side plots where plant communities were in their second year since establishment (i.e., intensive sites) and regionally distributed fields where plant communities had been in place for at least 10 years (i.e., extensive sites). We assessed microbial community structure and composition using lipid analysis, pyrosequencing of rRNA genes (targeting fungi, bacteria, archaea, and lower eukaryotes), and targeted metagenomics of nifH genes.

A layout like this would encourage plants to self-seed and spread, filling up the spaces to achieve the look of a small drier or upland prairie. All three approaches revealed similar differences among cropping systems in community structure. (2002) observed larger quantities of C and larger activity ratios in the soil of a restored prairie compared to a neighboring corn farmland. (2013) who also compared microbial soil communities under biofuel crops by pyrosequencing 16S rRNA and nifH genes and found that site‐to‐site variation surpassed variation stemming from plant type.

It also makes a superior cattle feed and the deep root system of switchgrass helps to build soil carbon. Ammonia‐oxidizing bacteria are the primary N2O producers in an ammonia‐oxidizing archaea dominated alkaline agricultural soil. We assume, however, that soil type is the key factor because of the sharp difference in soil texture and fertility between our intensive sites in the two states (Fig. IndVal results indicated Geobacter was significantly associated with Michigan sites and Bradyrhizobium and Rubrivivax were significantly associated with Wisconsin sites. In addition, the reverse primer included a 5 bp bar code (designated by above) for multiplexing of samples during sequencing. These primers target a 625 bp fragment of the large subunit (LSU) rRNA gene in fungi. Switchgrass, an herbaceous species, has been promoted as a potential biofuel feedstock and is highly adapted to the southern United States. Here, ‘state’ is actually a proxy for several correlated soil attributes, differing between intensive and extensive experiments, as explained in the Results section. Our initial hypothesis was that the cultivation of switchgrass and mixed grasses would lead to microbial communities more similar to those under prairie species, implying a more sustainable system. S2, Tables S1 and S2). Significance codes: ***0.001; **0.01; *0.05; NS, non significant. In addition, it is possible that the lower AMF richness under corn stemmed from higher soil disturbance in the cultivation of this crop, because there is evidence that soil disturbance was responsible for reducing the phylotype richness of AMF communities under seminatural grasslands (Schnoor et al., 2011). Bars represent ±1 standard error. ... ‘Heavy Metal’ thrives in prairie type settings or in sunny gardens with moist, average or dry soils. and you may need to create a new Wiley Online Library account. 4) and for differences in dispersion among factors. Relative abundances of prokaryotic and eukaryotic phyla determined from SSU rRNA gene sequences. The sequences contributing most significantly to the ordinations were identified using Biodiversity. Bacterial and fungal biomasses, especially biomass of arbuscular mycorrhizal fungi, were higher under perennial grasses and restored prairie, suggesting a more active carbon pool and greater microbial processing potential, which should be beneficial for plant acquisition and ecosystem retention of carbon, water, and nutrients. We decided the Poly primers were the current best choice because amplification with the broader coverage Zehr & McReynolds (1989) primers was troublesome, probably because of their high degeneracy. For the more recently established intensive sites, soil type was more important than plant community in determining microbial community structure, while plant community was the more important driver of soil microbial communities for the older extensive sites where microbial communities under corn were clearly differentiated from those under switchgrass and restored prairie. The output OTU0.03 tables were used for statistical analysis. 3a). Switchgrass produces high amounts of biomass and is a native species of North America that should require less intensive agricultural management than annual crops (Wright & Turhollow, 2010). S4). Tilman et al. Der Anbau von Nachwachsenden Rohstoffen ist in der  europäische Landwirtschaft zu einem festen Wirtschaftszweig geworden. q cutoff was 0.05. Crops are corn (CO), mixed grasses (MP), prairie (PR) and switchgrass (SW). Watch Store Tour. Influence of corn, switchgrass, and prairie cropping systems on soil microbial communities in the upper Midwest of the United States. 32115 Prairie Lane Winona, MN 55987; 866-417-8156; Email Us; Navigation . Switchgrass is a native, perennial, warm-season, sod-forming tall grass. We obtained 167 848 16S/18S rRNA gene sequences with an average of 7570 ± 894 sequences per sample and a minimum read length of 150 bp. We maintain optimal conditions for seed viability and freshness in our facilities. 1b). We found that only 0.13% of the sequences were classified to Glomeromycota. Our source-identified ecotypes come from our ever-expanding production fields and from a network of more than 70 seed producers located throughout the Midwest. The higher fungal biomass under perennial grasses implies greater potential for C accumulation under these crops (Blanco‐Canqui, 2010) because it is assumed that root production is higher (Zan et al., 2001), soil aggregates form more quickly and to a higher degree (Jastrow, 1987; Jarchow & Liebman, 2012) and that fungi produce C compounds more difficult to degrade (Allison et al., 2005).
