Expression of VjbR under nutrient limitation conditions is regulated at the post-transcriptional level by specific acidic pH values and urocanic acid
(Public Library Of Science, 2012-04)
VjbR is a LuxR homolog that regulates transcription of many genes including important virulence determinants of the facultative intracellular pathogen Brucella abortus. This transcription factor belongs to a family of ...
Humic extracts from hydrochar and Amazonian Anthrosol: Molecular features and metal binding properties using EEM-PARAFAC and 2D FTIR correlation analyses
(2020-10-01)
Organic matter plays many roles in the soil ecosystem. One property of the substance concerns the metal complexation and interaction with organic contaminants. In this sense, the humic substances (HS), a heterogeneous ...
Senses the Intracellular Environment through the BvrR/BvrS Two-Component System, Which Allows To Adapt to Its Replicative Niche
(2018-03-22)
Brucella abortus is a facultative extracellular-intracellular pathogen belonging to a group of Alphaproteobacteria that establishes close interactions with animal cells. This bacterium enters host cells in a membrane-bound ...

Reviewing microbial behaviors in ecosystems leading to a natural quorum quenching occurrence
(INST TECNOLOGIA PARANA, 2017-01-01)
Quorum sensing is considered one of the most important discoveries in cell-to-cell communication. Although revealed in Bacteria, it has been identified as well as a mechanism present in the other two domains, Eukaryota and ...

Gesso ou intervenção mecânica nas melhorias do gradiente de cátions do solo e na produtividade da soja e milho em plantio direto
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia - Agricultura e Ambiente, 2014-02-28)
The No-Tillage (NT) diffused in about 70 % of producing grain crops and has emerged as an alternative to soil losses due to the conventional tillage. However, it has been observed in recent years that the basic assumptions ...
