Gases tóxicos en silos de maíz de la planta entera: efecto sobre la salud y producción en vacas lecheras
(Instituto Nacional de Investigación Agropecuaria, Uruguay, 2024-03)Este artículo busca concientizar a productores y técnicos sobre los riesgos de la exposición a gases neumotóxicos por parte de animales y personas, los efectos que ocasionan, y la implementación de medidas preventivas ... -
Gene content and distribution in the nuclear genome of Fragaria vesca
(Crop Science Society of America, 2009-03)Thirty fosmids were randomly selected from a library of Fragaria vesca subsp. americana (cv. Pawtuckaway) DNA. These fosmid clones were individually sheared, and ∼4- to 5-kb fragments were subcloned. Subclones on a single ... -
Gene expression and in vitro replication of bovine gammaherpesvirus type 4
(Springer Verlag, 2021-02-05)In vitro cell cultures are widely used models for dissecting cellular and molecular mechanisms that lead to certain physiological conditions and diseases. The pathogenesis of BoHV-4 in the bovine reproductive tract has ... -
Genetic and biochemical biomarkers in the macrophyte Bidens laevis L. Exposed to a commercial formulation of endosulfan
(Wiley, 2014-09)Previous studies in the wetland macrophyte Bidens laevis L have demonstrated that the insecticide endosulfan induces a high frequency of somatic chromosome aberrations in anaphase–telophase (CAAT) but no DNA changes as ... -
Genetic and management factors affecting beef quality in grazing Hereford steers
(Elsevier, 2012-12)Attributes contributing to differences in beef quality of 206 Hereford steers finished on pasture were assessed. Beef quality traits evaluated were: Warner–Bratzler meat tenderness and muscle and fat color at one and seven ... -
Genetic characterization of bovine herpesvirus 4 (BoHV-4) isolates from Argentine cattle suggests a complex evolutionary scenario
(Springer Nature, 2020-04)Bovine herpevsirus 4 (BoHV-4) is a gammaherpesvirus that has been associated with different clinical conditions in cattle. In Argentina, BoHV-4 was detected in diverse bovine samples. The aim of this study was to analyze ... -
Genetic variability for leaf growth rate and duration under water deficit in sunflower: analysis of responses at cell, organ, and plant level
(Oxford Academic Press, 2008-05)Plants under water deficit reduce leaf growth, thereby reducing transpiration rate at the expense of reduced photosynthesis. The objective of this work was to analyse the response of leaf growth to water deficit in several ... -
Genetic Variation in FABP4 and Evaluation of Its Effects on Beef Cattle Fat Content
(2017-01-05)FABP4 is a protein primarily expressed in adipocytes and macrophages that plays a key role in fatty acid trafficking and lipid hydrolysis. FABP4 gene polymorphisms have been associated with meat quality traits in cattle, ... -
Genome-Wide Analyses of Aspartic Proteases on Potato Genome (Solanum tuberosum): Generating New Tools to Improve the Resistance of Plants to Abiotic Stress
(Multidisciplinary Digital Publishing Institute, MDPI, 2022-02)Aspartic proteases are proteolytic enzymes widely distributed in living organisms and viruses. Although they have been extensively studied in many plant species, they are poorly described in potatoes. The present study ... -
Genome-Wide Analyses of Subtilisin-Like Serine Proteases on Solanum tuberosum
(Springer Netherlands, 2016-10)Plant subtilisin-like serine proteases or subtilases constitute a large expanded gene subfamily in potato. We identified 82 potato subtilases encoded by 74 genes. All subtilases present a characteristic S08 domain, and the ... -
Genome-wide association analysis of agronomical and physiological traits linked to drought tolerance in a diverse potatoes (Solanum tuberosum) panel
(Wiley-Blackwell Publishing, 2021-06-12)Potatoes is often considered a drought-sensitive crop and its sustainable production is threatened due to frequent drought episodes. Drought tolerance is a complex trait of increasing importance in potatoes therefore its ... -
Genome-wide association study for resistance in bread wheat (Triticum aestivum L.) to stripe rust (Puccinia striiformis f. sp. tritici) races in Argentina
(BioMed Central, 2022-11-24)Background: Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most devastating diseases of the wheat crop. It causes significant reductions in both grain yield and grain quality. In ... -
Genomic diversity and phylodynamic of bovine viral diarrhea virus in Argentina
(Elsevier, 2021-12)Bovine viral diarrhea virus (BVDV) is an important pathogen of ruminants worldwide and is characterized by high genetic diversity and a wide range of clinical presentations. In Argentina, several studies have evaluated the ... -
Genomic evolution of bovine viral diarrhea virus based on complete genome and individual gene analyses
(Springer, 2023-05-23)Bovine viral diarrhea virus (BVDV) genome consists of a single-stranded, positive-sense RNA with high genetic diversity. In the last years, significant progress has been achieved in BVDV knowledge evolution through ... -
Genomic relationships between hexaploid Helianthus resinosus and diploid Helianthus annuus (Asteraceae)
(Springer, 2014-05)Genus Helianthus comprises diploid and polyploid species. An autoallopolyploid origin has been proposed for hexaploid species but the genomic relationships remain unclear. Mitotic and meiotic studies in annual Helianthus ... -
Germination and Vigor of Maize Seeds: Pilot-Scale Comparison of Low-Oxygen and Traditional Storage Methods
(Multidisciplinary Digital Publishing Institute, MDPI, 2024-08)Seed quality declines during storage depending on relative humidity, temperature, and oxygen concentration. Low-oxygen atmospheres significantly enhanced the germination and vigor of seeds during storage in laboratory-scale ... -
