Characterization of Cellulolytic Activities of Environmental Bacterial Consortia from an Argentinian Native Forest
(Springer, 2013-08)Cellulolytic activities of three bacterial consortia derived from a forest soil sample from Chaco region, Argentina, were characterized. The phylogenetic analysis of consortia revealed two main highly supported groups ... -
Deep cytogenetics analysis reveals meiotic recombination depletion in species of Senecio (Asteraceae)
(Springer Open, 2013-08)Background: Senecio is the largest genus in the Asteraceae family growing in all environments around the world. It displays taxonomic and systematical difficulties. Cytogenetic knowledge of this genus is ancient, scarce ... -
Population genetics structure of glyphosate‐resistant Johnsongrass (Sorghum halepense L. Pers) does not support a single origin of the resistance
(Wiley, 2013-09)Single sequence repeats (SSR) developed for Sorghum bicolor were used to characterize the genetic distance of 46 different Sorghum halepense (Johnsongrass) accessions from Argentina some of which have evolved toward ... -
Study of the in vivo role of Mce2R, the transcriptional regulator of mce2 operon in Mycobacterium tuberculosis
(BMC, 2013-09)Background: Tuberculosis is one of the leading causes of mortality throughout the world. Mycobacterium tuberculosis, the agent of human tuberculosis, has developed strategies involving proteins and other compounds called ... -
Draft genome sequence of Mycobacterium bovis 04-303, a highly virulent strain from Argentina
(American Society for Microbiology, 2013-11)Mycobacterium bovis strain 04-303 was isolated from a wild boar living in a free-ranging field in Argentina. This work reports the draft genome sequence of this highly virulent strain and the genomic comparison of its major ... -
Detección de un complejo clonal con el genotipo de Brucella abortus biovariedad 2 como fundador en aislamientos de B. abortus de Argentina = Detection of a clonal complex with Brucella abortus biovar 2 genotype as founder in B. abortus isolates from Argentina
(Asociación Argentina de Microbiología, 2013-12)Brucella abortus es el agente causal de la brucelosis bovina, enfermedad zoonótica que se encuentra ampliamente distribuida en el mundo. Actualmente existen ocho biovariedades de B. abortus. En Argentina se encuentra con ... -
Salicylic acid determines differential senescence produced by two turnip mosaic virus strains involving reactive oxygen species and early transcriptomic changes
(2013-12)Losses produced by virus diseases depend mostly on symptom severity. Turnip mosaic virus (TuMV) is one of the most damaging and widespread potyvirus infecting members of the family Brassicaceae, including Arabidopsis ... -
Mycobacterium intracellulare infection in a capybara (Hydrochoerus hydrochaeris)
(American Association of Zoo Veterinarians, 2013-12)This report describes the first case of Mycobacterium intracellulare infection with typical granulomatous lesions of mycobacteriosis in a capybara (Hydrochoerus hydrochaeris). The individual was a captive-bred young female, ... -
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. ... -
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. ... -
