Role of PhoPR in the response to stress of Mycobacterium bovis
(Elsevier, 2021-02)PhoP is part of the two-component PhoPR system that regulates the expression of virulence genes of Mycobacteria. The goal of this work was to elucidate the role of PhoP in the mechanism that Mycobacterium bovis, the causative ... -
Root hydraulic conductivity and adjustments in stomatal conductance: hydraulic strategy in response to salt stress in a halotolerant species
(Oxford University Press, 2015-11)Recent advances at the molecular level are introducing a new scenario that needs to be integrated into the analysis of plant hydraulic properties. Although it is not yet clear to what extent this scenario alters the current ... -
Rotavirus species tropism: new insights on P-type classification
(2018-11)To study the aminoacid regions that are involved in the VP8 pocket in order to find a molecular fingerprint for the virus species tropism. -
The rpl23 gene and pseudogene are hotspots of illegitimate recombination in barley chloroplast mutator seedlings
(Nature Publishing Group, 2019-07)Previously, through a TILLING (Targeting Induced Local Lesions in Genomes) approach applied on barley chloroplast mutator (cpm) seedlings a high frequency of polymorphisms in the rpl23 gene was detected. All the polymorphisms ... -
Rv2577 of Mycobacterium tuberculosis is a virulence factor with dual phosphatase and phosphodiesterase functions
(Frontiers Media, 2020-10)Tuberculosis, a lung disease caused by Mycobacterium tuberculosis (Mtb), is one of the ten leading causes of death worldwide affecting mainly developing countries. Mtb can persist and survive inside infected cells through ... -
Rv2617c and P36 are virulence factors of pathogenic mycobacteria involved in resistance to oxidative stress
(Taylor & Francis, 2019-12)In this study, we characterized the role of Rv2617c in the virulence of Mycobacterium tuberculosis. Rv2617c is a protein of unknown function unique to M. tuberculosis complex (MTC) and Mycobacterium leprae. In vitro, this ... -
Salicylic acid determines differential senescence produced by two turnip mosaic virus strains involving reactive oxygen species and early transcriptomic changes
(2013-12)Losses produced by virus diseases depend mostly on symptom severity. Turnip mosaic virus (TuMV) is one of the most damaging and widespread potyvirus infecting members of the family Brassicaceae, including Arabidopsis ... -
"Una Salud”: una mirada necesaria para comprender y abordar las emergencias
(Ediciones INTA, 2022-05)La emergencia de enfermedades infecciosas, principalmente entre especies, y el intercambio de material genómico entre agentes infecciosos genera condiciones favorables para la aparición de nuevas variantes de mayor ... -
SARS-CoV-2 RBD protein enhances the oncolytic activity of the vesicular stomatitis virus
(Frontiers Media, 2023-01)Despite recent advances in the research on oncolytic viruses (OVs), a better understanding of how to enhance their replication is key to improving their therapeutic index. Understanding viral replication is important to ... -
Science based criteria for a simplified risk assessment of genetic engineered crops developed using identical or similar constructs
(2016-08)Experience with Agricultural Biotechnology and the widespread adoption of different genetically engineered (GE) crops around the world has enabled breeders to develop different crops with similar phenotypic characteristics ... -
Secretion systems of pathogenic escherichia coli
(Springer International Publishing, 2016)Protein secretion plays a central role in modulating the interactions of bacteria with their environments. Bacterial ribosomes synthesize up to 8000 different proteins. Almost half of these become integrated in membranes ... -
Secretome profile of Cellulomonas sp. B6 growing on lignocellulosic substrates
(Wiley; Society for Applied Microbiology, 2018-12)Aims: Lignocellulosic biomass deconstruction is a bottleneck for obtaining biofuels and value‐added products. Our main goal was to characterize the secretome of a novel isolate, Cellulomonas sp. B6, when grown on residual ... -
Seed dormancy QTL identification across a Sorghum bicolor segregating population
(2016)Pre-harvest sprouting (PHS) in Sorghum bicolor is one of the main constrains for its production in the central region of Argentina, as grain maturation often coincides with rainy or high environmental humidity conditions. ... -
