Abstract A wide range of plant lines has been propagated by farmers during crop selection and dissemination, but consequences this diversification on plant‐microbe interactions have neglected. Our hypothesis was that evolutionary history shaped the way resulting interact with soil bacteria in their rhizospheres. Here, significance maize as a factor influencing seedling roots assessed comparing rhizobacterial community composition inbred representing five main genetic groups maize, cultivated...
The use of antibiotics in animal husbandry contributes to the worldwide problem increasing antibiotic resistance and human pathogens. Intensive production is considered an important source genes released environment, while contribution smaller farms remains be evaluated. Here we monitor spread tetracycline (TC-r) at a middle-size conventional dairy farm, where chlortetracycline (CTC, as intrauterine suppository) prophylactically used after each calving. Our study has shown that animals farm...
Manure is known to contain residues of antibiotics administered farm animals as well bacteria carrying antibiotic resistance genes (ARGs). These are often located on mobile genetic elements. In biogas plants (BGPs), organic substrates such manure and plant material mixed fermented in order provide energy, resulting digestates used for soil fertilization. The fate plasmid from during the fermentation process unknown. present study focused transferable plasmids seven BGPs, using a...
Abstract Bacterial genes responsible for resistance to antibiotic agents (ARG) are spread from livestock soil through application of manure, threatening environmental and human health. We investigated the mechanisms ARG dissemination persistence disentangle i) influence nutrients microorganisms on tetracycline (TET) resistome, ii) role indigenous microbiota in preventing spread. analysed short-term (7 days) persistent (84 effects manure resistome three antibiotic-free pasture soils.

Members of the Actinobacteria are among most important litter decomposers in soil. The site a waterlogged deciduous forest with acidic soil was explored for actinobacteria because seasonality inputs, temperature, and precipitation provided contrasting environmental conditions, particularly variation organic matter quantity quality. We hypothesized that these factors, which known to influence decomposition, were also likely affect actinobacterial community composition. relationship between...
Changes in the abundance of bacteria and fungi composition bacterial communities during primary succession were investigated a brown coal mine deposit area near Sokolov, Czech Republic, using phospholipid fatty acids analysis, microarray 16S rRNA gene sequencing. The study considered chronosequence sites undergoing spontaneous succession: 6-, 12-, 21- 45-year-old 21-year-old site revegetated withAlnus glutinosa. During succession, organic carbon total nitrogen content increased while pH C/N...
ABSTRACT The root disease take-all, caused by Gaeumannomyces graminis var. tritici , can be managed monoculture-induced take-all decline (TAD). This natural biocontrol mechanism typically occurs after a outbreak and is believed to arise from an enrichment of antagonistic populations in the rhizosphere. However, it not known whether these changes are induced monoculture or ecological rhizosphere conditions due subsequent attenuation. question was addressed comparing microflora barley, either...
Abstract Control of common scab disease can be reached by resistant cultivars or suppressive soils. Both mechanisms are likely to translate into particular potato microbiome profiles, but the relative importance each is not known. Here, microbiomes bulk and tuberosphere soil periderm were studied in one susceptible cultivar grown a conducive field. Disease severity was suppressed similarly both means yet, copy numbers txtB gene (coding for pathogenicity determinant) similar soils higher...
Abstract Background Deadwood decomposition is an essential ecological process in forest ecosystems, playing a key role nutrient cycling and carbon sequestration by enriching soils with organic matter. This driven diverse microbial communities encompassing specialized functions breaking down matter, but the specific roles of individual microorganisms this are still not fully understood. Results Here, we characterized deadwood microbiome natural mixed temperate Central Europe using PacBio HiFi...
Very few soil quality indicators include disease-suppressiveness criteria. We assessed whether 64 16S rRNA microarray probes whose signals correlated with tobacco black root rot suppressiveness in greenhouse analysis could also discriminate suppressive from conducive soils under field conditions. Rhizobacterial communities of and wheat sampled 2 years four farmers' fields contrasted status were compared. The previously identified indicator correctly classified 72% 29 samples, nine for...
Rapidly growing mycobacteria (RGM) inhabit soil and water but certain strains represent a health risk for human animals. Both clinical RGM may be under selection pressure resistance to tetracycline (TET) antibiotics, since tetracyclines are administrated humans farm animals, TET residues enter through manuring; however, the presence of TET-resistance genes have been assessed only in isolates. We were therefore interested comparing terms genes. used 44 from grasslands with different exposure...
Manure from dairy farms has been shown to contain diverse tetracycline resistance genes that are transferable soil. Here, we focus on conjugative plasmids may spread at a conventional farm. We performed exogenous plasmid isolation cattle feces using chlortetracycline for transconjugant selection. The transconjugants obtained harbored LowGC-type and tet(Y). A representative (pFK2-7) was fully sequenced this compared with previously described LowGC piggery manure-treated soil GenBank record...
Abstract The effect of environmental factors on bacterial and actinobacterial communities was assessed to predict microbial community structure in natural gradients. Bacterial were studied at four sites differing vegetation water regime: creek sediment, wet meadow, dry meadow deciduous forest located a shallow valley. by phytocoenological releves. T-RFLP quantitative PCR used determine composition abundances. Significant relationships between selected soil traits relatively close each other...
