Bases moleculares de la interacción virus-planta : relación entre genes de defensa, ARNs pequeños y sintomatología
(Facultad de Agronomía, Universidad de Buenos Aires, 2013-03)Los virus fitopatógenos producen alteraciones en el metabolismo y la fisiología de sus huéspedes provocadas principalmente por alteraciones en la expresión génica durante las infecciones. Numerosos cambios están asociados ... -
Direct effect of ozone pollution on aphids: revisiting the evidence at individual and population scales
(2015-04)Most of our knowledge about the consequences of tropospheric ozone pollution on aphid–plant interaction assumes the absence of a direct effect of ozone on aphids. However, the biological effects of ozone encompass changes ... -
Genomic comparison of two strains of Mycobacterium avium subsp. paratuberculosis with contrasting pathogenic phenotype
(Elsevier, 2023-01)In a previous study, we evaluated the degree of virulence of Mycobacterium avium subsp. paratuberculosis (Map) strains isolated from cattle in Argentina in a murine model. This assay allowed us to differentiate between ... -
Oligopeptide uptake improves oxidative stress resistance and nodulation competitiveness in soybean rhizobia
(Elsevier, 2023-12)We here explored the mechanisms associated with oxidative stress resistance and root colonization by soybean rhizobia. Genomic and physiological analyses supported the fact that the mutation of a highly conserved valine ... -
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 ... -
Whole-Genome Resequencing of Spontaneous Oxidative Stress-Resistant Mutants Reveals an Antioxidant System of Bradyrhizobium japonicum Involved in Soybean Colonization
(Springer, 2021-11)Soybean is the most inoculant-consuming crop in the world, carrying strains belonging to the extremely related species Bradyrhizobium japonicum and Bradyrhizobium diazoefficiens. Currently, it is well known that B. japonicum ...
