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 ... -
Simplified methodology for large scale isolation of homozygous transgenic lines of lettuce
(2018-01)Background: Lettuce is a globally important leafy vegetable and a model plant for biotechnology due to its adaptability to tissue culture and stable genetic transformation. Lettuce is also crucial for functional genomics ... -
Simultaneous carriage of mcr-1 and other antimicrobial resistance determinants in Escherichia coli from poultry
(Frontiers Media, 2018-07)The use of antimicrobial growth promoters (AGPs) in sub-therapeutic doses for long periods promotes the selection of resistant microorganisms and the subsequent risk of spreading this resistance to the human population and ... -
Single nucleotide polymorphisms from candidate genes associated with nematode resistance and resilience in Corriedale and Pampinta sheep in Argentina
(Elsevier, 2021-02)Selective breeding of genetically resistant animals is considered a promising strategy to face the problem of nematode resistance to anthelmintics and mitigate concerns about the presence of chemical residues in animal ... -
Single nucleotide polymorphisms in candidate genes associated with milk yield in Argentinean Holstein and Holstein x Jersey cows
(2018-12)Research on loci influencing milk production traits of dairy cattle is one of the main topics of investigation in livestock. Many genomic regions and polymorphisms associated with dairy production have been reported ... -
Single nucleotide polymorphisms may explain the contrasting phenotypes of two variants of a multidrug-resistant Mycobacterium tuberculosis strain
(2017)Globally, about 4.5% of new tuberculosis (TB) cases are multi-drug-resistant (MDR), i.e. resistant to the two most powerful first-line anti-TB drugs. Indeed, 480,000 people developed MDR-TB in 2015 and 190,000 people died ... -
Situación epidemiológica de la criptosporidiosis bovina en Argentina = Epidemiological situation of bovine cryptosporidiosis in Argentina
(Universidad de Morón, 2021-04)La criptosporidiosis en terneros neonatos es causada por protozoos enteroparásitos del género Cryptosporidium. Es una afección caracterizada por cuadros de diarrea y deshidratación, dando lugar a una reducción en la ... -
Síndrome diarreico en potrillos, diagnóstico y caracterización de los agentes virales involucrados
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2017-08)Las diarreas neonatales representan uno de los síndromes clínicos más relevantes y frecuentes en potrillos menores de 6 meses de edad. Rotavirus grupo A (RVA) es el principal agente viral asociado a diarreas en potrillos, ... -
Snakin-1 affects reactive oxygen species and ascorbic acid levels and hormone balance in potato
(PLOS, 2019-03-25)Snakin-1 is a member of the Solanum tuberosum Snakin/GASA family. We previously demonstrated that Snakin-1 is involved in plant defense to pathogens as well as in plant growth and development, but its mechanism of action ... -
Snakin/GASA proteins : involvement in hormone crosstalk and redox homeostasis
(Taylor & Francis, 2012)Snakin/GASA proteins are widely distributed among plant species. They are expressed in different plant organs with high tissue and temporal specificity, and their subcellular localization varies among the different members. ... -
SNP genotyping by heteroduplex analysis
(Springer, 2015-10)Heteroduplex-based genotyping methods have proven to be technologically effective and economically efficient for low- to medium-range throughput single-nucleotide polymorphism (SNP) determination. In this chapter we describe ... -
Solid state culture conditions for improved conidial production of the mycoparasitic fungus Escovopsis weberi
(Taylor & Francis, 2023-11-15)We evaluated culture conditions (temperature, substrate moisture content, agitation and light conditions) for optimising conidia production of Escovopsis weberi Ew1 using solid state culture. In addition, several substrates ... -
South American H4N2 influenza A virus improved replication in chicken trachea after low number of passages
(Frontiers Media, 2023-05)Introduction of influenza A viruses (FLUAV) into poultry from waterfowl is frequent, producing economic burden and increasing the probability of human infections. We have previously described the presence of FLUAV in wild ... -
Soybean in rotation with cereals attenuates nitrous oxide emissions as compared with soybean monoculture in the Pampas region
(Elsevier, 2021-11)Nitrous oxide (N-N2O) emissions in the agricultural sector represent ca. 25% of total N-N2O emissions on a global scale. In Argentina, information on agricultural emissions is scarce, and thus, N-N2O emissions are estimated ... -
Spatial distribution of Mycobacterium bovis spoligotypes in cattle from the state of Minas Gerais, Brazil
(Springer, 2022-07)Genotyping methods have led to a better understanding of the epidemiology of Mycobacterium bovis (M. bovis) infection, and its transmission dynamics, as well as the possible phylogenetic relationships between Mycobacterium ... -
Species diversity of Cladorrhinum in Argentina and description of a new species, Cladorrhinum australe
(Springer, 2015-10)The genus Cladorrhinum constitutes a fungal group of prime importance for agriculture and livestock, since some species have biocontrol potential or were shown to promote plant growth and to produce phytases, which are ... -
Spermatogenesis in the parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae)
(2017)The study of spermatogenesis in Hymenoptera is limited to few taxa due to limitations to access the material in the right stage for analysis. The information available up to now states that the gametogenesis in males ... -
Spontaneous Mutations in the Nitrate Reductase Gene napC Drive the Emergence of Eco-friendly Low-N2O-Emitting Alfalfa Rhizobia in Regions with Different Climates
(Springer, 2020)We have recently shown that commercial alfalfa inoculants (e.g., Sinorhizobium meliloti B399), which are closely related to the denitrifier model strain Sinorhizobium meliloti 1021, have conserved nitrate, nitrite, and ... -
Spontaneous virus reactivation in cattle chronically infected with bovine leukemia virus
