Sex Chromosome Turnover in Moths of the Diverse Superfamily Gelechioidea
(Oxford University Press, 2019-04-08)Sex chromosomes play a central role in genetics of speciation and their turnover was suggested to promote divergence. Invertebrates, sex chromosome–autosome fusions resulting in neo-sex chromosomes occur frequently in male ... -
Sex chromosomes in mitotic and polytene tissues of Anastrepha fraterculus (Diptera, Tephritidae) from Argentina: a review
(Pensoft Publishers, 2015-11)Cytogenetics, which is considered a fundamental tool to understand basic genetic and genomic issues of species, has greatly contributed to the description of polymorphisms both at inter- and intra-specific level. In fact, ... -
Shiga toxin-producing Escherichia coli (STEC) O22:H8 isolated from cattle reduces E. coli O157:H7 adherence in vitro and in vivo
(2017-09)Problem addressed: Shiga toxin-producing Escherichia coli (STEC) are a group of bacteria responsible for foodassociated diseases. Clinical features include a wide range of symptoms such as diarrhea, hemorrhagic colitis and ... -
Short communication: Relationship between the level of bovine leukemia virus antibody and provirus in blood and milk of cows from a naturally infected herd
(2016)We explored the relationship between the level of bovine leukemia virus antibodies and provirus load during natural infection. For that purpose, a set of 50 blood and milk paired samples were analyzed for the presence of ... -
Shortening of generation cycles in inbred lines of maize (Zea mays L.) through embryo rescue technique
(Istituto Sperimentale per la Cerealicoltura, 2019-11)Embryo rescue techniques have been used as an approach to raise hybrids from incompatible crosses. These techniques have also proved to be valuable tools for maize improvement, since they allow reducing the duration of the ... -
Signs of a phyllospheric lifestyle in the genome of the stress-tolerant strain Azospirillum brasilense Az19
(Elsevier, 2020-11)Azospirillum brasilense Az19 is a plant-beneficial bacterium capable of protecting plants from the negative effects of drought. The objective of this study was to determine and analyze the genomic sequence of strain Az19 ... -
Silencing of the glutathione biosynthetic pathway inhibits somatic embryogenesis in wheat
(Springer, 2013-02)Somatic embryogenesis in scutella of wheat (Triticum aestivum L.) is a well documented phenomenon and it has been shown through transcriptome analysis that genes involved in antioxidant responses, particularly in glutathione ... -
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 ... -

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. ... -
