The stringent response plays a key role in Bacillus subtilis survival of fatty acid starvation
(Wiley Blackwell Publishing, Inc, 2017-02)
The stringent response is a universal adaptive mechanism to protect bacteria from nutritional and environmental stresses. The role of the stringent response during lipid starvation has been studied only in Gram-negative ...
A stringent response-defective Bradyrhizobium diazoefficiens does not activate the type-3-secretion system, elicits early plant defense, and circumvents NH 4 NO 3 -induced inhibition of nodulation
(American Society for Microbiology, 2021-04-13)
When subjected to nutritional stress, bacteria modify their amino acid metabolism and cell division activities by means of the stringent response, which is controlled by the Rsh protein in alphaproteobacteria. An important ...
Transcriptomic changes of piscirickettsia salmonis during intracellular growth in a salmon macrophage-like cell line
(Frontiers Media, 2020)
Piscirickettsia salmonis is the causative agent of Piscirickettsiosis, a systemic infection of salmonid fish species. P. salmonis infects and survives in its host cell, a process that correlates with the expression of ...
Expression of Shigella flexneri gluQ-rs gene is linked to dksA and controlled by a transcriptional terminator
(2012)
Background: Glutamyl queuosine-tRNAAsp synthetase (GluQ-RS) is a paralog of the catalytic domain of glutamyl-tRNA synthetase and catalyzes the formation of glutamyl-queuosine on the wobble position of tRNAAsp. Here we ...
Systematic Production of Inactivating and NonInactivating Suppressor Mutations at the relA Locus That Compensate the Detrimental Effects of Complete spoT Loss and Affect Glycogen Content in Escherichia coli
(Public Library Of Science, 2014-09)
In Escherichia coli, ppGpp is a major determinant of growth and glycogen accumulation. Levels of this signaling nucleotide are controlled by the balanced activities of the ppGpp RelA synthetase and the dual-function ...
The politics of sanctioning the poor through welfare conditionality: revealing causal mechanisms in Uruguay [preprint]
(Universidad Católica del Uruguay, 2023)
What explains the ‘punitive turn’ toward more stringent conditionalities in welfare
policies? Answering this question is crucial in a region such as Latin America, where
cash transfers have proven politically consequential ...
Revisiting the stem proteome of Eucalyptus grandis and Eucalyptus globulus: Identification of temperature-induced changes
(2020-12-01)
Eucalyptus grandis and Eucalyptus globulus are important species for the Brazilian forestry industry. E. grandis plantations are mainly found in tropical regions, yet E. globulus plants are usually cultivated under moderate ...
Meson decays and physics beyond standard model
(2010)
In this thesis we discuss possible effects of new physics beyond the Standard Model
(SM) associated with high energy scales. We make special emphasis on their manifestations
in low energy processes such as meson decays. ...
