Composition and functionality of the wild and cultivated common bean rhizosphere microbiome. Repositório Alice
FLORES, S. W. S.; CHIARAMONTE, J. B.; ROSSMANN, M.; MENDES, R..
Abstract: Plants rely on their rhizosphere microbiome for specific functions, such as, nutrient acquisition and protection against diseases. The domestication and subsequent plant breeding neglected the important role of the rhizosphere microbiome on plant performance. Here, we tested the hypothesis that ancestor materials have higher ability to host beneficial microorganisms in the rhizosphere when compared to modern cultivars. For this, we assessed the composition and functionality of the rhizosphere microbiome associated with a wild (Wild Mex) and with a cultivated (IAC Alvorada) common bean grown in highly biodiverse soil (Amazonian Dark Earth). Antagonistic bacteria were isolated from common bean rhizosphere and total rhizosphere DNA was extracted for...

Construction and characterization of a metagenomic DNA library from the rhizosphere of wheat (Triticum aestivum) Phyton
Hernández-León,R; Martínez-Trujillo,M; Valencia-Cantero,E; Santoyo,G.
Rhizospheric soil of wheat plants contains a high diversity of microorganisms, and therefore, comprises a large reservoir for discovering genes with diverse agro-biotechnological applications. In this work, we constructed an E. coli metagenomic library based on bacterial artificial chromosome (BAC) clones with large genomic inserts from metagenomic DNA from the rhizosphere of wheat plants. The average of the DNA cloned segments varies from 5 to 80 kb, with an average size of 38 kb. Random clones were end-sequenced and homology results showed that the clonation of metagenomic DNA codes mainly for metabolic and catalytic functions (40%), including amidohydrolase, hydrolase, peptidase, serine protease, endonuclease and exonuclease. Another interesting...

Co-occurrence patterns of litter decomposing communities in mangroves indicate a robust community resistant to disturbances. Repositório Alice
TAKETANI, R. G.; MOITINHO, M. A.; MAUCHLINE, T.; MELO, I. S. de.
Abstract: Background. Mangroves are important coastal ecosystems known for high photosynthetic productivity and the ability to support marine food chains through supply of dissolved carbon or particular organic matter. Most of the carbon found in mangroves is produced by its vegetation and is decomposed in root associated sediment. This process involves a tight interaction between microbial populations, litter chemical composition, and environmental parameters. Here, we study the complex interactions found during litter decomposition in mangroves by applying network analysis to metagenomic data.

Functional Genes of Microorganisms, Comprehending the Dynamics of Agricultural Ecosystems BABT
Reali,Catiusca; Pilz Júnior,Harry Luiz; Meile,Jean Christophe; Galindo,Sabine Shorr; Fiuza,Lidia Mariana.
ABSTRACT The microbial composition of different types,in ecosystems (including agro-ecosystems), has been investigated in a rapidly growing number of studies in the past few years. The importance of microorganisms, regarding the maintenance and stability of nutrients in agroecosystems, is a key to maintain the sustainability of a crop. Molecular tools to study microbial communities are possible through many methods such as RISA, DGGE, TGGE, clone libraries, T-RFLP, RAPD, SSCP and more recently NGS (Next-Generation Sequencing). DGGE is widely employed to characterize the diversity and the community dynamics of microorganisms in the environment, making possible to find out specific groups through functional genes, allowing access to data that cannot be...

Genomic ecology of Marine Group II, the most common marine planktonic Archaea across the surface ocean ArchiMer
Pereira, Olivier; Hochart, Corentin; Auguet, Jean-christophe; Debroas, Didier; Galand, Pierre E..
Planktonic Archaea have been detected in all the world's oceans and are found from surface waters to the deep sea. The two most common Archaea phyla are Thaumarchaeota and Euryarchaeota. Euryarchaeota are generally more common in surface waters, but very little is known about their ecology and their potential metabolisms. In this study, we explore the genomic ecology of the Marine Group II (MGII), the main marine planktonic Euryarchaeota, and test if it is composed of different ecologically relevant units. We re‐analyzed Tara Oceans metagenomes from the photic layer and the deep ocean by annotating sequences against a custom MGII database and by mapping gene co‐occurrences. Our data provide a global view of the distribution of Euryarchaeota, and more...

Holobionts and their hologenomes: Evolution with mixed modes of inheritance Genet. Mol. Biol.
Haag,Karen Luisa.
Abstract Symbioses are ubiquitous and have played an influential role in the evolution of life on Earth. Genomic studies are now revealing a huge diversity of associations among hosts and their microbiotas, allowing us to characterize their complex ecological and evolutionary dynamics. The different transmission modes and the asynchronous cell proliferation of the numerous symbionts associated with one host generate a genomic conflict ought to be solved. Two disputing views have been used to model and predict the outcome of such conflicts. The traditional view is based on community ecology, and considers that selection at the level of individuals is sufficient to explain longstanding associations among species. A new perspective considers that the host and...

Metagenomic analysis of the rhizosphere microbiome of the common bean resistant to Fusarium oxysporum. Repositório Alice
MENDES, L. W.; MENDES, R.; TSAI, S. M..
The rhizosphere microbiome plays a key role in the functioning of the host plant, influencing its physiology and development. It has been suggested that plants use mechanisms present in the rhizosphere microbiome to fend off infections, such as fungal diseases. This work aimed to assess the microbial community inhabiting the common bean rhizosphere in order to identify potential groups related to the suppression of the soil-borne pathogen Fusarium oxysporum. Therefore, using shotgun metagenomic sequencing (Illumina Miseq), we investigated the phylogenetic and potential functional diversity of microbial communities colonizing the rhizosphere of four cultivars of common bean with different levels of resistance to the fungus, ranging from high susceptibility...

Metagenomic sequencing of environmental DNA reveals marine faunal assemblages from the West Antarctic Peninsula ArchiMer
Cowart, Dominique; Murphy, Katherine R.; Cheng, C. -h. Christina.
The West Antarctic Peninsula (WAP) is the fastest warming region in Antarctica where climate impact on the cold-adapted marine ecosystem is already visible. To monitor faunal changes in remote vast bodies of Antarctic waters, efficient and informative tools are essential. High-throughput sequencing of environmental DNA (eDNA) has emerged as one such tool for monitoring biodiversity and ecosystems, as it increases detection sensitivity of taxa, and sampling is often simpler and less costly than traditional collection methods. We collected water samples from four WAP shallow (≤ 300 m) shelf regions, recovered the eDNA therein, and performed metagenomic shotgun sequencing and analyses to determine the effectiveness of this method to assess marine benthic...

Mining of the endophytic microbiome for novel biosynthetic genes and antifungal metabolites. Repositório Alice
CARRION, V. J.; PÉREZ-JARAMILLO, J.; CORDOVEZ, V.; HOLLANDER, M. de; TRACANNA, V.; MENDES, L. W.; MENDES, R.; MEDEMA, M. H.; RAAIJMAKERS, J. M..
Endophytic microbes have been proposed to contribute to a range of plant support functions, including nutrient acquisition and disease protection. To date, the molecular mechanisms underlying disease protection in the endosphere have only been studied for individual culturable organisms. Here, we conducted a systematic microbiome-wide perspective on the taxonomic diversity and functional potential of the endophytic microbiome of plants grown in an agricultural soil that is naturally suppressive to damping-off disease caused by the fungal root pathogen Rhizoctonia solani. Metagenomic analyses showed an enrichment of Burkholderiaceae, Chitinophagaceae and Xanthomonadaceae in the endosphere of plants grown in disease-suppressive soil challenged with the...
