Aislamiento y caracterización de regiones promotoras de girasol para dirigir la expresión tejido específica de genes foráneos a semilla
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2014-04)Desde el inicio de la utilización de variedades transgénicas, la superficie agrobiotecnológica ha aumentado exponencialmente, con un incremento del orden de 80 veces en solo 14 años, y su uso se ha expandido a más de veinte ... -
Atrazine alters early sexual development of the South American silverside, Odontesthes bonariensis
(Elsevier, 2022-11)Atrazine (ATZ) is a frequent contaminant in freshwater ecosystems within agricultural regions. The capacity of this herbicide to interfere with the vertebrate endocrine system is broadly recognized, but the mechanisms and ... -
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 ... -
Beyond arabidopsis: differential UV-B response mediated by UVR8 in diverse species
(Frontiers Media, 2019-06)Ultraviolet-B radiation (UV-B, 280–315 nm) is an important environmental signal that regulates growth and development in plants. Two dose-dependent UV-B response pathways were described in plants: a specific one, mediated ... -
Cell remodeling and subtilase gene expression in the actinorhizal plant Discaria trinervis highlight host orchestration of intercellular Frankia colonization
(2018-08)Nitrogen‐fixing filamentous Frankia colonize the root tissues of its actinorhizal host Discaria trinervis via an exclusively intercellular pathway. Here we present studies aimed at uncovering mechanisms associated with ... -
Characterization and validation of olive FAD and SAD gene families: expression analysis in diferent tissues and during fruit development
(Springer, 2020-05-28)Stearoyl-ACP desaturases (SADs) and fatty acid desaturases (FADs) play a critical role in plant lipid metabolism and also afect oil fatty acid composition introducing double bonds into the hydrocarbon chains to produce ... -
Characterization of the two component regulatory system PhoPR in Mycobacterium bovis
(Elsevier, 2018-08)Mycobacterium bovis is the causative agent of bovine tuberculosis and is a member of Mycobacterium tuberculosis complex, which causes tuberculosis in a number of mammals including humans. Previous studies have shown that ... -
Comparative transcriptome analysis of geographically distinct virulent and attenuated Babesia bovis strains reveals similar gene expression changes through attenuation
(2013-11)Background: Loss of virulence is a phenotypic adaptation commonly seen in prokaryotic and eukaryotic pathogens. This mechanism is not well studied, especially in organisms with multiple host and life cycle stages such as ... -
Comparison of transient and stable expression of foot-and-mouth disease virus capsid proteins in mammalian cells
(Scientific Research, 2013-12)Foot-and-mouth disease is a highly contagious disease that produces severe economic losses in the livestock industry. This disease is being controlled by the use of an inactivated vaccine. However, the use of recombinant ... -
Development, characterization and experimental validation of a cultivated sunflower (Helianthus annuus L.) gene expression oligonucleotide microarray
(PLOS One, 2012-10)Oligonucleotide-based microarrays with accurate gene coverage represent a key strategy for transcriptional studies in orphan species such as sunflower, H. annuus L., which lacks full genome sequences. The goal of this study ... -
Differential DNA methylation and gene expression during development of reproductive and vegetative organs in Ilex species
(Springer, 2021-03)Differential epigenetic (DNA cytosine methylation) and gene expression patterns were investigated in reproductive and vegetative organs from Ilex paraguariensis and I. dumosa, at distinct developmental stages. We aimed at ... -
Down-regulation of catalase activity contributes to senescence induction in wheat leaves exposed to shading stress
(Springer, 2015-01)In shaded wheat (Triticum aestivum L.) leaves, the suppression of blue radiation (BR) triggers senescence. This phenomenon is correlated to an increase in oxidative stress symptoms and a decrease of catalase (CAT) activity, ... -
Drought controls on H2O2 accumulation, catalase (CAT) activity and CAT gene expression in wheat
(Society for Experimental Biology, 2005-01)Plants co-ordinate information derived from many diverse external and internal signals to ensure appropriate control of gene expression under optimal and stress conditions. In this work, the relationships between catalase ... -
