Rol de los microorganismos del suelo en el secuestro de C y la estabilidad agregada
(Universidad Nacional de Hurlingham, 2022-03-10)Nueva evidencia compilada por Lehmann y Kleber [1] descarta la teoría de la recalcitrancia como mecanismo de estabilización del C en el suelo (COS), fortaleciendo la conceptualización del secuestro de C como una función ... -
Rol del sistema antioxidante de microsimbiontes de leguminosas y su relación con la tolerancia a estrés abiótico durante la simbiosis
(Facultad de Ciencias Exactas, Físico - Químicas y Naturales, Universidad Nacional de Río Cuarto, 2019-03)La sequía y la salinidad son los principales factores que afectan la fijación biológica de nitrógeno mediada por la simbiosis rizobio/leguminosa. Una de las respuestas globales a estas condiciones de estrés es el aumento ... -
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 ... -
Roots are the key for soil C restoration: A comparison of land management in the semiarid Argentinean Pampa
(Elsevier, 2024-01-01)The objective of the study was to elucidate the relationship between soil management and carbon (C) stocks, and to identify the factors that intervene in the processes that favor C sequestration. The study was carried out ... -
Rotación de cultivos en la producción de tabaco: Efecto sobre algunas propiedades edáficas
(Asociación Argentina de la Ciencia del Suelo, 2021-02-02)El cultivo de tabaco requiere numerosas labores, lo que sumado al escaso volumen de rastrojos que deja este cultivo, se favorece el deterioro físico, químico y biológico del suelo. El objetivo fue evaluar en un suelo del ... -
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
