RinA controls phage-mediated packaging and transfer of virulence genes in gram-positive bacteria
(Oxford University Press, 2011)
Artículo / Artikulua,
Phage-mediated transfer of microbial genetic elements plays a crucial role in bacterial life style and evolution. In this study, we identify the RinA family of phage-encoded proteins as activators required for transcription ...
Nontypable haemophilus influenzae displays a prevalent surface structure molecular pattern in clinical isolates
(Public Library of Science, 2011)
Artículo / Artikulua,
Non-typable Haemophilus influenzae (NTHi) is a Gram negative pathogen that causes acute respiratory infections and is associated with the progression of chronic respiratory diseases. Previous studies have established the ...
Identification of the ovine mannose receptor and its possible role in Visna/Maedi virus infection
(BioMed Central, 2011)
info:eu-repo/semantics/article,
This study aims to characterize the mannose receptor (MR) gene in sheep and its role in ovine visna/maedi virus (VMV) infection. The deduced amino acid sequence of ovine MR was compatible with a transmembrane protein having ...
Brucella abortus ornithine lipids are dispensable outer membrane components devoid of a marked pathogen-associated molecular pattern
(Public Library of Science, 2011)
Artículo / Artikulua,
The brucellae are alpha-Proteobacteria facultative intracellular parasites that cause an important zoonosis. These bacteria escape early detection by innate immunity, an ability associated to the absence of marked ...
Depletion of the heaviest stable N isotope is associated with NH4+/NH3 toxicity in NH4+-fed plants
(BioMed Central, 2011)
Artículo / Artikulua,
Background: In plants, nitrate (NO3-) nutrition gives rise to a natural N isotopic signature (δ15N), which correlates
with the δ15N of the N source. However, little is known about the relationship between the δ15N of the ...
Genome-wide antisense transcription drives mRNA processing in bacteria
(National Academy of Sciences, 2011)
Artículo / Artikulua,
RNA deep sequencing technologies are revealing unexpected levels of complexity in bacterial transcriptomes with the discovery of abundant noncoding RNAs, antisense RNAs, long 5′ and 3′ untranslated regions, and alternative ...
Sucrose synthase activity in the sus1/sus2/sus3/sus4 Arabidopsis mutant is sufficient to support normal cellulose and starch production
(National Academy of Sciences, 2011)
info:eu-repo/semantics/article,
Sucrose synthase (SUS) catalyzes the reversible conversion of
sucrose and a nucleoside diphosphate into the corresponding
nucleoside diphosphate-glucose and fructose. In Arabidopsis,
a multigene family encodes six SUS ...
Isotopic composition of maize as related to N-fertilization and irrigation in the Mediterranean region
(Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2011)
info:eu-repo/semantics/article,
Nitrate leaching as a result of excessive application of N-fertilizers and water use is a major
problem of vulnerable regions. The farming of maize requires high N fertilization and water inputs in Spain.
Isotopic ...
The amino- and carboxyl-terminal fragments of the Bacillus thuringensis Cyt1Aa toxin have differential roles on toxin oligomerization and pore formation
(American Chemical Society, 2011)
info:eu-repo/semantics/article,
The Cyt toxins produced by the bacteria Bacillus thuringiensis show insecticidal activity against
some insects, mainly dipteran larvae, being able to kill mosquitoes and black flies. However, they
also possess a general ...
Intra- and intergenerational persistence of an insect nucleopolyhedrovirus: adverse effects of sublethal disease on host development, reproduction, and susceptibility to superinfection
(American Society for Microbiology, 2011)
info:eu-repo/semantics/article,
Sublethal infections by Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) are common in field
populations of the beet armyworm (S. exigua, Hübner) in the Almerian horticultural region of Spain. Inoculation
of ...
