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. ... -
Identificación y caracterización funcional de genes candidatos asociados a la senescencia foliar en girasol basado en perfiles transcripcionales y metabólicos
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2014)El proceso de senescencia en plantas es un mecanismo complejo controlado por múltiples variables genéticas y ambientales que condicionan el rendimiento de los cultivos. En el caso del girasol, el segundo cultivo oleaginoso ... -
TMV-Cg Coat Protein stabilizes DELLA proteins and in turn negatively modulates salicylic acid-mediated defense pathway during Arabidopsis thaliana viral infection
(2014)Background Plant viral infections disturb defense regulatory networks during tissue invasion. Emerging evidence demonstrates that a significant proportion of these alterations are mediated by hormone imbalances. Although ... -
Transferability of microsatellite markers located in candidate genes for wood properties between Eucalyptus species
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2014)AIM OF STUDY: To analyze the feasibility of extrapolating conclusions on wood quality genetic control between different Eucalyptus species, particularly from species with better genomic information, to those less characterized. ... -
Genome-wide data (ChIP-seq) enabled identification of cell wall-related and aquaporin genes as targets of tomato ASR1, a drought stress-responsive transcription factor
(BMC, 2014-01)Background: Identifying the target genes of transcription factors is important for unraveling regulatory networks in all types of organisms. Our interest was precisely to uncover the spectrum of loci regulated by a widespread ... -
The P0 protein encoded by cotton leafroll dwarf virus (CLRDV) inhibits local but not systemic RNA silencing
(2014-02)Plants employ RNA silencing as a natural defense mechanism against viruses. As a counter-defense, viruses encode silencing suppressor proteins (SSPs) that suppress RNA silencing. Most, but not all, the P0 proteins encoded ... -
Silencing of the tomato Sugar Partitioning Affecting protein (SPA) modifies sink strength through a shift in leaf sugar metabolism
(Wiley; Society for Experimental Biology, 2014-03)Limitations in our understanding about the mechanisms that underlie source-sink assimilate partitioning are increasingly becoming a major hurdle for crop yield enhancement via metabolic engineering. By means of a ... -
Purification and characterization of a GH43 β-xylosidase from Enterobacter sp. identified and cloned from forest soil bacteria
(Elsevier, 2014-03)The use of lignocellulosic biomass for second generation biofuels requires optimization of enzymatic breakdown of plant cell walls. In this work, cellulolytic bacteria were isolated from a native and two cultivated forest ... -
Detection of Mycobacterium bovis in Bovine and Bubaline tissues using Nested-PCR for TbD1
(PLOS, 2014-03)In the present study, a nested-PCR system, targeting the TbD1 region, involving the performance of conventional PCR followed by real-time PCR, was developed to detect Mycobacterium bovis in bovine/bubaline tissue homogenates. ... -
Immunogenicity of hypothetical highly conserved proteins as novel antigens in Anaplasma marginale
(Springer, 2014-03)Anaplasma marginale is a tick-transmitted Gram-negative intraerythrocytic bacterium and the etiological agent of bovine Anaplasmosis. Even though considerable research efforts have been undertaken, Anaplasmosis vaccine ... -
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 ... -
Artificial microRNAs as antiviral strategy to FMDV: structural implications of target selection
(2014-04)RNA interference (RNAi) appears as a promising strategy to control virus replication. While the antiviral power of short-hairpin RNAs or small-interfering RNAs against FMDV has been demonstrated widely, safer RNAi effectors ... -
Improving clustering with metabolic pathway data
(BMC, 2014-04)Background: It is a common practice in bioinformatics to validate each group returned by a clustering algorithm through manual analysis, according to a-priori biological knowledge. This procedure helps finding functionally ... -
Natural occurring epialleles determine vitamin E accumulation in tomato fruits
(2014-07)Vitamin E (VTE) content is a low heritability nutritional trait for which the genetic determinants are poorly understood. Here, we focus on a previously detected major tomato VTE quantitative trait loci (QTL; mQTL9-2-6) ... -
Estudio de los cambios transcriptómicos producidos por infecciones virales en plantas, rol de fitohormonas y su vinculación con la progresión de síntomas
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2014-08)Las pérdidas en cultivos ocasionadas por virus dependen mayormente de la severidad de los síntomas producidos. La comprensión de los mecanismos moleculares que subyacen a la producción de síntomas es de importancia para ... -
Pre-columbian mycobacterial genomes reveal seals as a source of new world human tuberculosis
(Springer Nature, 2014-08)Modern strains of Mycobacterium tuberculosis from the Americas are closely related to those from Europe, supporting the assumption that human tuberculosis was introduced post-contact1. This notion, however, is incompatible ... -
Experimental selection of long‐term intracellular mycobacteria
(Wiley, 2014-09)Some intracellular bacteria are known to cause long‐term infections that last decades without compromising the viability of the host. Although of critical importance, the adaptations that intracellular bacteria undergo ... -
The genome of the stress-tolerant wild tomato species Solanum pennellii
(Nature Publishing Group, 2014-09)Solanum pennellii is a wild tomato species endemic to Andean regions in South America, where it has evolved to thrive in arid habitats. Because of its extreme stress tolerance and unusual morphology, it is an important ... -
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 ... -
