A cultura da cana-de-açúcar é de extrema importância no cenário agrícola nacional. No entanto, pouco se sabe sobre a estruturação das comunidades microbianas associadas aos solos e às rizosferas de tais plantas. O objetivo deste trabalho foi avaliar a estrutura e diversidade das comunidades de bactérias associadas ao solo e à rizosfera de seis variedades de cana-de-açúcar cultivadas no Estado de São Paulo (Brasil). As análises foram realizadas com base em métodos independentes de cultivo, em que a técnica de PCR-DGGE revelou alterações na rizosfera para os grupos de bactérias totais e também para os grupos de Alphaproteobacteria e Betaproteobacteria. Após essa análise, quatro amostras (três de rizosfera e uma de solo) foram usadas para o sequenciamento da...

Exploring interactions of plant microbiomes
Provedor de dados: 63
Autores: Andreote,Fernando Dini; Gumiere,Thiago; Durrer,Ademir.
A plethora of microbial cells is present in every gram of soil, and microbes are found extensively in plant and animal tissues. The mechanisms governed by microorganisms in the regulation of physiological processes of their hosts have been extensively studied in the light of recent findings on microbiomes. In plants, the components of these microbiomes may form distinct communities, such as those inhabiting the plant rhizosphere, the endosphere and the phyllosphere. In each of these niches, the "microbial tissue" is established by, and responds to, specific selective pressures. Although there is no clear picture of the overall role of the plant microbiome, there is substantial evidence that these communities are involved in disease control, enhance...

Temporal assessment of microbial communities in soils of two contrasting mangroves
Provedor de dados: 58

ABSTRACT Variations in microbial communities promoted by alterations in environmental conditions are reflected in similarities/differences both at taxonomic and functional levels. Here we used a natural gradient within mangroves from seashore to upland, to contrast the natural variability in bacteria, cyanobacteria and diazotroph assemblages in a pristine area compared to an oil polluted area along a timespan of three years, based on ARISA (bacteria and cyanobacteria) and nifH T-RFLP (diazotrophs) fingerprinting. The data presented herein indicated that changes in all the communities evaluated were mainly driven by the temporal effect in the contaminated area, while local effects were dominant on the pristine mangrove. A positive correlation of community...
