Analysis of the rhizosphere microbial communities of common beans resistant and susceptible to Fusarium oxysporum. Repositório Alice
MENDES, L. W.; MENDES, R.; TSAI, S. M..
The rhizosphere is the narrow zone of soil around the living plant roots that is influenced by the activity of the plants. Many beneficial microorganisms in the rhizosphere provide plants with mineral nutrients, phytohormones, and also help to protect the plant against soil-borne pathogens. Microbiological studies are addressed to understand how rhizosphere microorganisms are recruited from soil and either benefit or harm plant growth, nutrition and health. Here, we aimed to identify potential microbial groups and functional traits correlated to the suppression of the soil borne pathogen Fusarium oxysporum, the causal agent of Fusarium wilt on common beans. We used shotgun metagenomics to investigate the rhizosphere microbiome of two common bean cultivars...

Back to the roots: revealing beneficial interactions between the rhizosphere microbiome and wild wheat. Repositório Alice
ROSSMANN, M.; PÉREZ-JARAMILLO, J. E.; CHIARAMONTE, J. B.; KAVAMURA, V. N.; DUMACK, K.; FIORE-DONNO, A. M.; MENDES, L. W.; BONKOWSKI, M.; MAUCHLINE, T.; RAAIJMAKERS, J. M.; MENDES, R..
Domestication of plants may have impacted the interactions between plants and their rhizosphere microbiome. Considering that plants rely on the rhizosphere microbiome for functions related with plant growth, nutrition and health, the objective of this work was to analyse the rhizosphere microbiome of wild relatives and modern varieties of wheat and to investigate whether wild relatives recruit a higher proportion of beneficial microbes than modern cultivars. By 16S-rRNA gene amplicon, ITS and 18SrRNA gene amplicon, we assessed the bacterial, fungal and cercozoa rhizosphere community composition of five modern cultivars and three wheat ancestors cultivated in forest and agricultural soils. Results revealed a pronounced soil type and rhizosphere effect on...

Breeding for resistance to soil-borne pathogen impacts rhizosphere microbiome functions in common bean. Repositório Alice
MENDES, L. W.; MENDES, R.; RAAIJMAKERS, J. M.; TSAI, S. M..
Over the past century, plant breeding programs have substantially improved plant growth and health, but have not yet considered the potential effects on the plant microbiome. Here, we conducted a metatranscriptome analysis to determine if and how breeding for resistance of common bean against the root pathogen Fusarium oxysporum (Fox) affected gene expression in the rhizobacterial community. Our data revealed that rhizobacterial community assembly of Fox-resistant and susceptible bean cultivars follows niche-based mechanisms, presenting lower diversity and distinct community structure compared to the bulk soil. The microbiome of the Fox-resistant bean cultivar presented a significantly higher expression of bacterial genes associated with nutrient...

Cross-kingdom similarities in microbiome ecology and biocontrol of pathogens. Repositório Alice
BERG, G.; KRAUSE, R.; MENDES, R..
Abstract: The concept of "gut and root microbiota commonalities" was already presented by Ramírez-Puebla et al.(2013); they discussed a lot of similar functional traits, host-bacteria interactions as well as evolutionary trends but also several differences. Based on deeper insights obtained by omics technologies, Mendes and Raaijmakers (2015) recently presented their concept that the structure and function of rhizosphere and gut microbiomes showcross-kingdom similarities. In parallel, Hacquard et al. (2015) analyzed similarities of the microbiota composition across plant and animal kingdoms and found only little overlap comparing fish gut and plant root communities. They explained the differences by various start inoculants and abiotic, niche-specific...

Impact of plant domestication on rhizosphere microbiome assembly and functions. Repositório Alice
PÉREZ-JARAMILLO, J. E.; MENDES, R.; RAAIJMAKERS, J. M..
Abstract: The rhizosphere microbiome is pivotal for plant health and growth, providing defence against pests and diseases, facilitating nutrient acquisition and helping plants to withstand abiotic stresses. Plants can actively recruit members of the soil microbial community for positive feedbacks, but the underlying mechanisms and plant traits that drive microbiome assembly and functions are largely unknown. Domestication of plant species has substantially contributed to human civilization, but also caused a strong decrease in the genetic diversity of modern crop cultivars that may have affected the ability of plants to establish beneficial associations with rhizosphere microbes. Here, we review how plants shape the rhizosphere microbiome and how...

Impacto da domesticação do trigo em sua interação com bactérias benéficas da rizosfera. Repositório Alice
CARVALHO, J. C. de; COSTA, L. S. A. S.; CHIARAMONTE, J. B.; ROSSMANN, M.; MENDES, R..
Resumo: O processo de domesticação do trigo, como outras espécies cultivadas, está relacionado à formação de civilizações sedentárias. A domesticação consiste na seleção de caracteres fenotípicos úteis para uso humano. A transição do ambiente natural para sistemas de produção modernos geram diversas mudanças no ambiente que podem acarretar em impactos na microbiota do solo cultivado. As plantas vivem em associação com microrganismos que auxiliam em funções como defesa, saúde e crescimento da planta, e esta associação deve-se a um longo processo de coevolução. Assumindo que existe a dependência dessa microbiota, acredita-se que cultivares modernos perderam algumas características para recrutar microrganismos específicos do hospedeiro durante o processo de...

Inorganic nitrogen application affects both taxonomical and predicted functional structure of wheat rhizosphere bacterial communities. Repositório Alice
KAVAMURA, V. N.; HAYAT, R.; CLARK, I. M.; ROSSMANN, M.; MENDES, R.; HIRSCH, P. R.; MAUCHLINE, T. H..
The effects of fertilizer regime on bulk soil microbial communities have been well studied, but this is not the case for the rhizosphere microbiome. The aim of this work was to assess the impact of fertilization regime on wheat rhizosphere microbiome assembly and 16S rRNA gene-predicted functions with soil from the long term Broadbalk experiment at Rothamsted Research. Soil from four N fertilization regimes (organic N, zero N, medium inorganic N and high inorganic N) was sown with seeds of Triticum aestivum cv. Cadenza. 16S rRNA gene amplicon sequencing was performed with the Illumina platform on bulk soil and rhizosphere samples of 4-week-old and flowering plants (10 weeks). Phylogenetic and 16S rRNA gene-predicted functional analyses were performed....

Microbiome of the Black-Lipped Pearl Oyster Pinctada margaritifera, a Multi-Tissue Description With Functional Profiling ArchiMer
Dubé, Caroline; Ky, Chin-long; Planes, Serge.
Elucidating the role of prokaryotic symbionts in mediating host physiology has emerged as an important area of research. Since oysters are the world’s most heavily cultivated bivalve molluscs, numerous studies have applied molecular techniques to understand the taxonomic and functional diversity of their associated bacteria. Here, we expand on this research by assessing the composition and putative functional profiles of prokaryotic communities from different organs/compartments of the black-lipped pearl oyster Pinctada margaritifera, a commercially important shellfish valued for cultured pearl production in the Pacific region. Seven tissues, in addition to mucous secretions, were targeted from P. margaritifera individuals: the gill, gonad, byssus gland,...

Microbiomes of Velloziaceae from phosphorus-impoverished soils of the campos rupestres, a biodiversity hotspot. Repositório Alice
CAMARGO, A. P.; SOUZA, R. S. C. de; COSTA, P. de B.; GERHARDT, I. R.; DANTE, R. A.; TEODORO, G. S.; ABRAHÃO, A.; LAMBERS, H.; CARAZZOLLE, M. F.; HUNTEMANN, M.; CLUM, A.; FOSTER, B.; FOSTER, B.; ROUX, S.; PALANIAPPAN, K.; VARGHESE, N.; MUKHERJEE, S.; REDDY, T. B. K.; DAUM, C.; COPELAND, A.; CHENM U, M. A.; IVANOVA, N. N.; KYRPIDES, N. C.; PENNACCHIO, C.; ELOE-FADROSH, E. A.; ARRUDA, P.; OLIVEIRA, R. S..
The rocky, seasonally-dry and nutrient-impoverished soils of the Brazilian campos rupestres impose severe growth-limiting conditions on plants. Species of a dominant plant family, Velloziaceae, are highly specialized to low-nutrient conditions and seasonal water availability of this environment, where phosphorus (P) is the key limiting nutrient. Despite plant-microbe associations playing critical roles in stressful ecosystems, the contribution of these interactions in the campos rupestres remains poorly studied. Here we present the first microbiome data of Velloziaceae spp. thriving in contrasting substrates of campos rupestres. We assessed the microbiomes of Vellozia epidendroides, which occupies shallow patches of soil, and Barbacenia macrantha, growing...

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...

Outstanding impact of soil tillage on the abundance of soil hydrolases revealed by a metagenomic approach. Repositório Alice
SOUZA, R. C.; CANTAO, M. E.; NOGUEIRA, M. A.; VASCONCELOS, A. T. R.; HUNGRIA, M..
Abstract: The soil represents the main source of novel biocatalysts and biomolecules of industrial relevance. We searched for hydrolases in silico in four shotgun metagenomes (4,079,223 sequences) obtained in a 13-year field trial carried out in southern Brazil, under the no-tillage (NT), or conventional tillage (CT) managements, with crop succession (CS, soybean/wheat), or crop rotation (CR, soybean/maize/wheat/lupine/oat). We identified 42,631 hydrolases belonging to five classes by comparing with the KEGG database, and 44,928 sequences by comparing with the NCBI-NR database. The abundance followed the order: lipases > laccases > cellulases > proteases > amylases > pectinases. Statistically significant differences were attributed to the...

THE HUMAN MICROBIOTA: THE ROLE OF MICROBIAL COMMUNITIES IN HEALTH AND DISEASE Acta biol.Colomb.
BOTERO,Luz Elena; DELGADO-SERRANO,Luisa; CEPEDA HERNÁNDEZ,Martha Lucía; DEL PORTILLO OBANDO,Patricia; ZAMBRANO EDER,María Mercedes.
During the last decade, there has been increasing awareness of the massive number of microorganisms, collectively known as the human microbiota, that are associated with humans. This microbiota outnumbers the host cells by approximately a factor of ten and contains a large repertoire of microbial genome-encoded metabolic processes. The diverse human microbiota and its associated metabolic potential can provide the host with novel functions that can influence host health and disease status in ways that still need to be analyzed. The microbiota varies with age, with features that depend on the body site, host lifestyle and health status. The challenge is therefore to identify and characterize these microbial communities and use this information to learn how...

The spermosphere effect: building up plant microbiome assembly. Repositório Alice
PÉREZ-JARAMILLO, J. E.; CARRION, V. J.; HOLLANDER, M. de; MENDES, R.; RAAIJMAKERS, J. M..
Plants have a significant influence on the diversity and activity of soil microbial communities. During imbibition and germination, plant seeds release chemically diverse exudates thereby promoting microbial activity in the zone surrounding the seed, also referred to as the spermosphere. To date, little is known about the diversity and activities of microbial communities in the spermosphere and how this short-lived plant developmental stage affects microbiome assembly. Here, we deciphered the magnitude of the spermosphere effect for two different food crops, i.e. tomato and bean. More specifically, we investigated if a plant genotype-dependent influence is discernible in the spermosphere and to what extent the spermosphere microbiome relates to the...
