Genomic responses to climate: Understanding local adaptation in the Andean tree species Nothofagus pumilio and implications for a changing world
(Wiley, 2024-03)Nothofagus pumilio is a foundation tree species that inhabits a 2000-km-long range in the southern Andes, a region with two perpendicular environmental gradients: temperature and photoperiod (North–South), and precipitation ... -
Genomic selection in Canadian spruces
(Springer, 2020-01-01)The genetic gain of spruce (Picea spp.) breeding programs is impeded by long recurrent selection cycles stemming from biological constraints such as late expression of traits, weak juvenile mature correlations, and late ... -
Genomic-based breeding for climate-smart peach varieties
(Springer, 2020)Improving the performance of peach varieties in the context of climate change requires multiple approaches. Not only will climate change alter plant phenology, but it will also drive negative effects of several biotic and ... -
Genomic-based multiple-trait evaluation in Eucalyptus grandis using dominant DArT markers
(2018-06)We investigated the impact of combining the pedigree- and genomic-based relationship matrices in a multiple-trait individual-tree mixed model (a.k.a., multiple-trait combined approach) on the estimates of heritability and ... -
Genomics-assisted breeding for quantitative disease resistances in small-grain cereals and maize
(MDPI, 2020-12-19)Generating genomics-driven knowledge opens a way to accelerate the resistance breeding process by family or population mapping and genomic selection. Important prerequisites are large populations that are genomically ... -
Genotipificación de variantes de beta-caseína bovina mediante ACRSPCR- RFLP = Genotyping of bovine beta-casein variants by ACRS-PCR-RFLP
(Consejo de Rectores de Universidades Privadas, 2023-10)Las variantes de la beta-caseína bovina pueden clasificarse en dos grupos, tipo-A1 y tipo-A2, según el aminoácido que esté presente en la posición 67 de la proteína (His, tipo A1; Pro, tipo A2)1. En los últimos años se ha ... -
Genotoxic effects induced by Cd+2, Cr+6, Cu+2 in the Gill and Liver of Odontesthes bonariensis (Piscies, Atherinopsidae)
(2016)Genotoxic effects of Cd?2, Cr?6, and Cu?2 on the gill and liver of the Argentinean Silverside (Odontesthes bonariensis) were studied using the comet assay and in relation with the metal tissue accumulation. Fish were exposed ... -
Genotypic and environmental effects on the concentration of bulb phytochemicals associated with garlic flavor, health-enhancing properties, and postharvest conservation
(Wiley, 2022-05)To estimate genetic and environmental effects on traits associated with garlic functional value and postharvest quality, the content of total organosulfur compounds, phenolics, and solids were determined in selected garlic ... -
Genotypic and phenotypic detection of capsular polysaccharide and biofilm formation in Staphylococcus aureus isolated from bovine milk collected from Brazilian dairy farms
(2016-12)Staphylococcus aureus is a pathogen that frequently causes mastitis in bovine herds worldwide. This pathogen produces several virulence factors, including cell-associated adhesins, toxic and cytolytic exoproteins, and ... -
Genotypic Characterization of Non-O157 Shiga Toxin–Producing Escherichia coli in Beef Abattoirs of Argentina
(2011-12)The non-O157 Shiga toxin–producing Escherichia coli (STEC) contamination in carcasses and feces of 811 bovines in nine beef abattoirs from Argentina was analyzed during a period of 17 months. The feces of 181 (22.3%) bovines ... -
Genotypic variation in response to salinity in a new sexual germplasm of Cenchrus ciliaris L.
(2016)As part of breeding program for new salt- tolerant sexual genotypes of Cenchrus ciliaris L., we evaluated the salt- stress response of two new sexual hybrids, obtained by controlled crosses, at seedling and germination stages. -
Genotypic variation of physiological and morphological traits of seven olive cultivars under sustained and cyclic drought in Mendoza, Argentina
(2018-01-31)The effects of two deficit irrigation regimes on the physiological, morphological, vegetative, and reproductive traits of seven olive cultivars were studied in a pot experiment. Specific leaf area (SLA) and SPAD chlorophyll ... -
