Microorganisms that use nitrate as an alternative terminal electron acceptor play important role in the global nitrogen cycle. The diversity of nitrate-reducing community soil and influence maize roots on structure this were studied. narG gene encoding membrane bound reductase was selected a functional marker for community. is special interest because phylogeny closely reflects 16S ribosomal DNA phylogeny. Therefore, targeting provided first time unique insight into taxonomic composition...
Summary In order to understand the effect of maize rhizosphere on denitrification, diversity and activity denitrifying community were studied in soil amended with mucilage. Diversity was investigated by polymerase chain reaction (PCR) amplification total DNA extracted from soils using gene fragments, encoding nitrate reductase ( narG ) nitrous oxide nosZ ), as molecular markers. To assess underlying diversity, PCR products cloned 10 libraries obtained for each targeted gene. Libraries...
We report the characterisation of Nocardioides sp. SP12, an atrazine-degrading bacteria isolated from atrazine-treated bulk- and maize rhizosphere soil. Based on 16S rDNA alignment, strain SP12 showed close phylogenic relationships with C157 simplex. Internal transcribed spacer (ITS) sequences were longer than those other present Ala- Ile-tRNA unlike Actinomycetales. presents a novel atrazine catabolic pathway combining trzN atzB atzC. Atrazine biodegradation ends in metabolite that...
The current challenge in agriculture is to move from intensively managed multifunctional agricultural landscapes that can simultaneously provide multiple ecological functions (multifunctionality), thus ensuring the delivery of ecosystem services important for human well-being. There evidence biodiversity main driver functions. However, how biodiversity, and which components are sources multifunctionality, remain elusive. In present study, we explore role weed richness abundance as possible...
A greenhouse study was conducted to investigate the ability of four crops (wheat, corn, oilseed rape and soybean) influence degradation bentazone, diclofop-methyl, diuron, isoproturon pendimethalin in soil. The present showed that microbial biomass-carbon significantly higher planted soils than bulk soil, especially with wheat after several cropping cycles. biomass corn soybean adversely affected by bentazone but recovered three In wheat-planted soils, diclofop-methyl application resulted...
Maintaining biodiversity is one of the key issues sustainable agriculture. It now stated that innovation to enhance in arable land requires operational assessment tools like indicators. The goal article provide an overview available Besides measured indicators and simple based on management data, we focus predictive derived from models adapted ex ante innovative cropping design. possibility use for each indicator type discussed.
In this study, endophytic bacteria belonging to the Bacillus genus were isolated from in vitro bulblets of Leucojum aestivum and their ability produce Amaryllidaceae alkaloids was studied. Proton Nuclear Magnetic Resonance (1H NMR)-based metabolomics combined with multivariate data analysis chosen compare metabolism plant (in vivo bulbs, bulblets) those community. Primary metabolites quantified by quantitative 1H NMR (qNMR) method. The results showed that tyrosine, one precursor alkaloid...
Abstract We report the development of quantitative competitive (QC) PCR assays for quantifying 16S, 18S ribosomal and atzC genes in nucleic acids directly extracted from soil. QC‐PCR were standardised, calibrated evaluated with an experimental study aiming to evaluate impact atrazine application on soil microflora. Comparison 16S results those microbial biomass showed that, following application, was not affected that amount rDNA gene representing ‘bacteria’ increased transitorily, while...
Abstract Hop ( Humulus lupulus L.) is an emblematic industrial crop in the French North East region that developed at same time as brewing activity. Presently, this sector, especially microbreweries, are interested endemic wild hops, which give beer production a local signature. In study, we investigated genetic and metabolic diversity of thirty-six hops sampled various ecological environments. These accessions were propagated aeroponically cultivated under uniform conditions (the soil...
