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 ... -
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 ... -
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 ... -
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 ... -
Exploring sunflower responses to Sclerotinia head rot at early stages of infection using RNA‑seq analysis
(Springer Nature, 2020-08)Sclerotinia head rot (SHR), caused by the necrotrophic fungus Sclerotinia sclerotiorum, is one of the most devastating sunflower crop diseases. Despite its worldwide occurrence, the genetic determinants of plant resistance ... -
Genome-wide identification of MITE-derived microRNAs and their targets in bread wheat
(BioMed Central, 2022-02)Background: Plant miRNAs are a class of small non-coding RNAs that can repress gene expression at the post-transcriptional level by targeting RNA degradation or promoting translational repression. There is increasing ... -
Identification of candidate genes associated with leaf senescence in cultivated sunflower (Helianthus annuus L.)
(PLOS, 2014)Cultivated sunflower (Helianthus annuus L.), an important source of edible vegetable oil, shows rapid onset of senescence, which limits production by reducing photosynthetic capacity under specific growing conditions. ... -
Nuevas estrategias para la transformación y expresión de genes de interés en girasol
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2011-09)El girasol es una especie de la familia Asteraceae (Compositae) de gran importancia económica, considerada hasta hace una década recalcitrante al cultivo in vitro y la transformación genética. En un trabajo previo (Radonic, ... -
Reference gene selection for gene expression studies using RT-qPCR in virus-infected planthoppers
(BioMed Central, 2011-12)Background: Planthoppers not only severely affect crops by causing mechanical damage when feeding but are also vectors of several plant virus species. The analysis of gene expression in persistently infected planthoppers ... -
Tomato Abscisic Acid Stress ripening (ASR) gene family revisited
(PLOS, 2014-10-13)Tomato ABSCISIC ACID RIPENING 1 (ASR1) was the first cloned plant ASR gene. ASR orthologs were then cloned from a large number of monocot, dicot and gymnosperm plants, where they are mostly involved in response to abiotic ... -
Transcriptomic Analysis Reveals a Differential Gene Expression Profile Between Two Sunflower Inbred Lines with Different Ability to Tolerate Water Stress
(Springer, 2020-01)Although sunflower (Helianthus annuus L.) is categorized as a medium drought-sensitive crop, in a changing climate scenario and/or with the onset of early droughts, the crop may be affected by water stress. This study ... -
Validation of reference genes for quantitative PCR in Johnsongrass (Sorghum halepense L.) under glyphosate stress
(MDPI, 2021-08)Weeds are one of the main causes of the decrease in crop yields, with Johnsongrass (Sorghum halepense L.) being one of the most significant. Weeds can be controlled by herbicides, but some have developed resistance. ...
