Abstract Microbial communities play important roles in all ecosystems and yet a comprehensive understanding of the ecological processes governing assembly these is missing. To address role biotic interactions between microorganisms for functioning soil microbiota, we used top-down manipulation approach based on removal various populations natural microbial community. We hypothesized that certain groups will strongly affect relative fitness many others, therefore unraveling contribution...
Abstract Background Microbes typically live in communities where individuals can interact with each other numerous ways. However, knowledge on the importance of these interactions is limited and derives mainly from studies using a number species grown coculture. Here, we manipulated soil microbial to assess contribution between microorganisms for assembly microbiome. Results By combining experimental removal (taxa depletion community) coalescence (mixing control communities) approaches,...
Abstract Microbial inoculants are attracting growing interest in agriculture, but their efficacy remains unreliable relation to poor survival, partly due the competition with soil resident community. We hypothesised that recurrent inoculation could gradually alleviate this and improve survival of inoculant while increasing its impact on bacterial tested effectiveness such strategy four sequences Pseudomonas fluorescens strain B177 microcosms number frequency inoculation, compared a...
Abstract Despite the large morphological and physiological changes that plants have undergone through domestication, little is known about their impact on microbiome. Here we characterized rhizospheric bacterial fungal communities as well abundance of N-cycling microbial guilds across thirty-nine accessions tetraploid wheat, Triticum turgidum , from four domestication groups ranging wild subspecies to semi dwarf elite cultivars. We identified several phylotypes displaying significant...
Abstract The plant plasma membrane (PM) plays a key role in nutrition, cell homeostasis, perception of environmental signals, and set-up appropriate adaptive responses. An exhaustive quantitative description the whole set lipids proteins constituting PM is thus necessary to understand how way these components, are organized interact together, allow fulfill such essential physiological functions. Here we provide by state-of-the-art approaches first combined reference lipidome proteome from...
Chronic and repeated exposure of environmental bacterial communities to anthropogenic antibiotics have recently driven some antibiotic-resistant bacteria acquire catabolic functions, enabling them use as nutritive sources (antibiotrophy). Antibiotrophy might confer a selective advantage facilitating the implantation dispersion antibiotrophs in contaminated environments. A microcosm experiment was conducted test this hypothesis an agroecosystem context. The sulfonamide-degrading resistant...
Highly diverse and abundant organisms coexist in soils. However, the contribution of biotic interactions between soil to microbial community assembly remains be explored. Here, we assess extent which fauna can shape using an exclusion experiment a grassland field sort biota based on body size. After 1 year, larger favoured phagotrophic protists, with increases up 32% their proportion compared no-mesh treatment. In contrast, members bacterial lesser fungal were negatively impacted. Shifts but...
During arbuscular mycorrhizal symbiosis, arbuscule-containing root cortex cells display a proliferation of plastids, feature usually ascribed to an increased plant anabolism despite the lack studies focusing on purified plastids. In this study, we investigated mycorrhiza-induced changes in plastidic pathways by performing label-free comparative subcellular quantitative proteomic analysis targeted plastid-enriched fractions isolated from Medicago truncatula roots, coupled cytological plastid...
Membrane microdomains are defined as highly dynamic, sterol- and sphingolipid-enriched domains that resist to solubilization by non-ionic detergents. In plants, these so-called Detergent Insoluble (DIM) fractions have been isolated from plasma membrane using conventional ultracentrifugation on density gradient (G). animals, a rapid (R) protocol, based sedimentation at low speed, which avoids the time-consuming sucrose gradient, has also developed recover DIMs microsomes starting material....
Maize cultivators often use β-triketone herbicides to prevent the growth of weeds in their fields. These target 4-HPPD enzyme dicotyledons. This enzyme, encoded by hppd gene, is widespread among all living organisms including soil bacteria, which are considered as “non-target organisms” legislation. Within framework pesticide registration process, ecotoxicological impact on microorganisms solely based carbon and nitrogen mineralization tests. In this study, we used more extensive approaches...
Under agroforestry practices, inter-specific facilitation between tree rows and cultivated alleys occurs when plants increase the growth of their neighbors especially under nutrient limitation. Owing to a coarse root architecture limiting soil inorganic phosphate (Pi) uptake, walnut trees ( Juglans spp.) exhibit dependency on soil-borne symbiotic arbuscular mycorrhizal fungi that extend extra-radical hyphae beyond Pi depletion zone. To investigate benefits walnuts in alley cropping, we...
ABSTRACT We report here the 7,259,392-bp draft genome of Pseudomonas sp. strain ADP. This is a bacterial that was first isolated in 1990s from soil for its ability to mineralize herbicide atrazine. It has extensively been studied as model understand atrazine biodegradation pathway. will be used reference and compared evolved populations obtained by experimental evolution conducted on this under selection pressure.
