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...

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...

Effect of phosphorus limitation on the microbial community assembly in the common bean (Phaseolus vulgaris L.) rhizosphere. Repositório Alice
CHIARAMONTE, J. B.; ROSSMANN, M.; MENDES, R..
Abstract: The indiscriminate use of inputs in agricultural systems, particularly phosphate, combined with the need of growing food production, is causing the depletion of phosphorus mines around the world. In order to mitigate the environmental impact caused by phosphorus exploration microorganisms can be used to increase the efficiency of phosphorus utilization in crop systems by promoting nutrient solubilization and absorption. It is believed that low phosphorus concentration in soil, enriches specific members of the rhizosphere microbiome related to the availability of this element to the plant. In this study, a factorial experiment was performed considering contrasting cultivars in the uptake efficiency of phosphorus (being IAC-Imperador and DOR-364,...

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....

Land management and microbial seed load effect on rhizosphere and endosphere bacterial community assembly in wheat. Repositório Alice
KAVAMURA, V. N.; ROBINSON, R. J.; HAYAT, R.; CLARK, I. M.; HUGHES, D.; ROSSMANN, M.; HIRSCH, P. R.; MENDES, R.; MAUCHLINE, T. H..
Abstract: Microbial community ecology studies have traditionally utilized culture-based methodologies, though the advent of next-generation amplicon sequencing has facilitated superior resolution analyses of complex microbial communities. Here, we used culture-dependent and -independent approaches to explore the influence of land use as well as microbial seed load on bacterial community structure of the wheat rhizosphere and root endosphere. It was found that niche was an important factor in shaping the microbiome when using both methodological approaches, and that land use was also a discriminatory factor for the culture-independent-based method. Although culture-independent methods provide a higher resolution of analysis, it was found that in the...

Quantification of the mycorrhizal fungal community associated with a modern wheat cultivar (Triticum aestivum) and with a wheat ancestor. Repositório Alice
ROSSMANN, M.; CHIARAMONTE, J. B.; MENDES, R..
Abstract: Plant breeding is an important instrument to improve crop productivity. However, studies have shown that plant breeding, as well as the use of management practices such as tillage and fertilization, influence the plant root microbiome and also may have caused reduction in the genetic diversity of modern cultivars when compared to their ancestors. As the rhizosphere microbiome can profoundly impact plant growth, nutrition and health, we hypothesized that plant breeding can negatively affect the recruitment of beneficial microbes in the rhizosphere and interactions with their favorable microbial partners. A greenhouse experiment was conducted to assess the composition of the rhizosphere mycorrhizal fungi community in wheat (Triticum aestivum)...

Rhizosphere bacterial communities as a strategy in wheat protection against root rot caused by Bipolaris sorokiniana. Repositório Alice
FARIA, M. R. de; COSTA, L. S. A. S.; CHIARAMONTE, J. B.; ROSSMANN, M.; BETTIOL, W.; MENDES, R..
The sustainable agriculture requires the use of advanced and modern technologies with the capacity to increase productivity to feed a world growing population demand. In this context, plant breeding associated with the studies of the rhizosphere microbiome may be an innovative strategy in plant protection against soil-borne pathogens. However, few studies investigate the structure and biodiversity of microbial communities in ancestral genotypes and recent cultivars associated with the plant defense process. Thereby, considering the impact of domestication and plant breeding on interactions in the plant rhizosphere microbiome, in this study, we compared the tolerance level of ancestral and recent wheat genotypes to Bipolaris sorokiniana and its correlation...

The role of common bean rhizosphere bacterial communities on phosphorus mobilization. Repositório Alice
CHIARAMONTE, J. B.; BULGARELLI, D.; COSTA, L. S. A. S.; ROSSMANN, M.; MENDES, R..
Acid soils are known for their high phosphate fixation potential, leading to an overage application of fertilizers. Microorganisms play important role in nutrient availability in the rhizosphere helping plants with phosphorus mobilization and uptake. We hypothesize that less efficient cultivars in phosphorus uptake, insoluble sources of phosphorus and limiting conditions of phosphorus in the soil could enrich the rhizosphere microbiome related to the availability of this nutrient. We performed a completely randomized factorial experiment with two common bean cultivars contrasting in phosphorus uptake efficiency growing in triple superphosphate or rock phosphate gradients. Sequencing of 16S rRNA amplicons were performed to access the rhizosphere community...

Wheat breeding influences root traits and selection of bacterial communities in the rhizosphere. Repositório Alice
KAVAMURA, V. N.; CLARK, I.; HIRSCH, P. R.; CAULFIELD, J.; SARRIA, A. F.; ROSSMANN, M.; BIRKETT, M.; MELO, I. S. de; MENDES, R.; MAUCHLINE, T..
During the Green Revolution, wheat breeding developed high-yielding plants with dwarfing genes. This selection led to structural changes in wheat, which could have consequences for the associated microbial communities, however, to date, little is known about these. The main goal of this work was to study rhizosphere bacterial communities from eight hexaploid wheat cultivars grown under field conditions ranging in chronology from Chidham White Chaff, a tall cultivar from 1790, to Crusoe, a semi dwarf cultivar from 2012. Plants were harvested, DNA from rhizosphere soil was extracted and 16S rRNA gene subjected to Illumina amplicon sequencing. Root architecture information and exudate profiles were obtained. The breeding process appears to have influenced...

Wheat rhizosphere bacterial communities and tolerance against root rot caused by Fusarium graminearum. Repositório Alice
COSTA, L. S. A. S.; FARIA, M. R. de; CHIARAMONTE, J. B.; ROSSMANN, M.; BETTIOL, W.; MENDES, R..
The rhizosphere microbiome is essential for health and development of plants, providing protection against pests and diseases. Domestication of plant species may have affected the biodiversity of microbial communities in ancestral plant roots compared to the modern plants, which may have changed the defense process. As ancestral genotypes and modern cultivars may present different levels of tolerance to the pathogens, we investigated the correlation between eight wheat genotypes, including wild materials and cultivars, and the structure of microbial communities in the rhizosphere. We evaluated the variation in susceptibility to the pathogen by inoculating Fusarium graminearum in the soil six days after sowing. The level of disease was assessed four weeks...
