Sous les projecteurs du concept d’holobionte et de méta-holobionte, une nouvelle révolution copernicienne ? Philippe Vandenkoornhuyse Université de Rennes 1, CNRS, UMR6553 ECOBIO, Avenue Leclerc, 35042 Rennes Cedex Nous n'avons jamais été seuls! Notre corps est colonisé par une diversité et une richesse importante de microorganismes formant le microbiote. Tous les macroorganismes, constituent un habitat colonisé par un microbiote. On sait maintenant que ce microbiote joue un role clé dans la valeur sélective individuelle de leur hôte. Se pose donc la question de l’individualité. Doit-on considérer l’hote de manière individuel, avec le microbiote vu comme passager clandestin et temporaire ou vu comme un écosystème hébergé par l’hote ou encore, doit on considérer l’hote et son symbiote comme formant une entité émergente, l’holobionte correspondant à l’individu ? Pour répondre à cette question conceptuelle et philosophique majeures, ce qu’est un individu, des travaux expérimentaux s’imposent. Le concept d’holobionte et la théorie de l’hologénome sont débattus principalement par le fait que si l’holobionte est unité de sélection, les gènes de l’hotes et ceux du microbiote seraient sélectionnés ensemble et héritables.

  • Supplementary Material 16S Rrna Clone Library
    Kip et al. Biogeosciences (bg-2011-334) Supplementary Material 16S rRNA clone library To investigate the total bacterial community a clone library based on the 16S rRNA gene was performed of the pool Sphagnum mosses from Andorra peat, next to S. magellanicum some S. falcatulum was present in this pool and both these species were analysed. Both 16S clone libraries showed the presence of Alphaproteobacteria (17%), Verrucomicrobia (13%) and Gammaproteobacteria (2%) and since the distribution of bacterial genera among the two species was comparable an average was made. In total a 180 clones were sequenced and analyzed for the phylogenetic trees see Fig. A1 and A2 The 16S clone libraries showed a very diverse set of bacteria to be present inside or on Sphagnum mosses. Compared to other studies the microbial community in Sphagnum peat soils (Dedysh et al., 2006; Kulichevskaya et al., 2007a; Opelt and Berg, 2004) is comparable to the microbial community found here, inside and attached on the Sphagnum mosses of the Patagonian peatlands. Most of the clones showed sequence similarity to isolates or environmental samples originating from peat ecosystems, of which most of them originate from Siberian acidic peat bogs. This indicated that similar bacterial communities can be found in peatlands in the Northern and Southern hemisphere implying there is no big geographical difference in microbial diversity in peat bogs. Four out of five classes of Proteobacteria were present in the 16S rRNA clone library; Alfa-, Beta-, Gamma and Deltaproteobacteria. 42 % of the clones belonging to the Alphaproteobacteria showed a 96-97% to Acidophaera rubrifaciens, a member of the Rhodospirullales an acidophilic bacteriochlorophyll-producing bacterium isolated from acidic hotsprings and mine drainage (Hiraishi et al., 2000).

  • Novel and Unexpected Bacterial Diversity in An
    Delavat et al. Biology Direct 2012, 7:28 http://www.biology-direct.com/content/7/1/28 RESEARCH Open Access Novel and unexpected bacterial diversity in an arsenic-rich ecosystem revealed by culture-dependent approaches François Delavat, Marie-Claire Lett and Didier Lièvremont* Abstract Background: Acid Mine Drainages (AMDs) are extreme environments characterized by very acid conditions and heavy metal contaminations. In these ecosystems, the bacterial diversity is considered to be low. Previous culture-independent approaches performed in the AMD of Carnoulès (France) confirmed this low species richness. However, very little is known about the cultured bacteria in this ecosystem. The aims of the study were firstly to apply novel culture methods in order to access to the largest cultured bacterial diversity, and secondly to better define the robustness of the community for 3 important functions: As(III) oxidation, cellulose degradation and cobalamine biosynthesis. Results: Despite the oligotrophic and acidic conditions found in AMDs, the newly designed media covered a large range of nutrient concentrations and a pH range from 3.5 to 9.8, in order to target also non-acidophilic bacteria. These approaches generated 49 isolates representing 19 genera belonging to 4 different phyla. Importantly, overall diversity gained 16 extra genera never detected in Carnoulès. Among the 19 genera, 3 were previously uncultured, one of them being novel in databases. This strategy increased the overall diversity in the Carnoulès sediment by 70% when compared with previous culture-independent approaches, as specific phylogenetic groups (e.g. the subclass Actinobacteridae or the order Rhizobiales) were only detected by culture. Cobalamin auxotrophy, cellulose degradation and As(III)-oxidation are 3 crucial functions in this ecosystem, and a previous meta- and proteo-genomic work attributed each function to only one taxon.

  • Habitat Heterogeneity and Connectivity Shape Microbial

However, very little is known of how habitat heterogeneity afects the structure of the bacterial communities in these ecosystems. Here, we used amplicon sequencing of the 16S rRNA and nifH genes to investigate phylogenetic diversity and bacterial community composition in three diferent sub-Antarctic peat bog aquatic habitats: Sphagnum magellanicum interstitial water, and water from vegetated and non-vegetated pools. Total and putative nitrogen-fxing bacterial communities from Sphagnum interstitial water difered signifcantly from vegetated and non-vegetated pool communities (which were colonized by the same bacterial populations), probably as a result of diferences in water chemistry and biotic interactions. Total bacterial communities from pools contained typically aquatic taxa, and were more dissimilar in composition and less species rich than those from Sphagnum interstitial waters (which were enriched in taxa typically from soils), probably refecting the reduced connectivity between the former habitats. These results show that bacterial communities in peatland water habitats are highly diverse and structured by multiple concurrent factors. Bacterial communities in peat bog ecosystems contribute signifcantly to nutrient cycling, to carbon sequestra- tion and to greenhouse gas emissions1–4. However, we still have a limited knowledge of the diversity and spatial distribution of bacterial assemblages in peat bogs.

In particular, preliminary research suggests that exposure to a high diversity of microbes during early life, for example through living in highly vegetated environments like farms or forests, may have specific health benefits, including immune system development and stimulation.
