Validation of housekeeping genes for qPCR in maize during water deficit stress conditions at flowering time
(2017)Plant stress studies are increasingly being based on gene expression. The analysis of gene expression requires sensitive, precise, and replicable measurements for specific mRNA sequences. Real-time RT-PCR is nowadays the ... -
Validation of reference genes for quantitative PCR in Johnsongrass (Sorghum halepense L.) under glyphosate stress
(MDPI, 2021-08)Weeds are one of the main causes of the decrease in crop yields, with Johnsongrass (Sorghum halepense L.) being one of the most significant. Weeds can be controlled by herbicides, but some have developed resistance. ... -
Variación genética de la resistencia a las parasitosis gastrointestinales en ovinos Corriedale = Genetic variation in resistance to gastrointestinal parasites in Corriedale sheep
(Consejo de Rectores de Universidades Privadas, 2023-10)Las infestaciones por nematodos gastrointestinales (NGI) en ovinos producen pérdidas económicas importantes en la producción agropecuaria y la situación empeora ante la aparición de parásitos resistentes a los antihelmínticos ... -
Variantes hiperproductoras de proteínas insecticidas de Bacillus thuringiensis obtenidas por mutagénesis inducida aumentan toxicidad para Alphitobius diaperinus
(Asociación Argentina de Microbiología, 2021-09-15)La producción avícola puede verse afectada por Alphitobius diaperinus (Coleoptera: Tenebrionidae). Su control se basa principalmente en el empleo de productos químicos. La utilización de una herramienta de control ... -
Variation in the VP1 Gene of Foot-And-Mouth Disease Virus Serotype a Associated with Epidemiological Characteristics of Outbreaks in the 2001 Epizootic in Argentina
(Sage Publishing, 2008)A mixed binomial Bayesian regression model was used to quantify the relation between nucleotide differences in the VP1 gene of Foot-and-mouth disease virus (FMDV) serotype A, and epidemiologic characteristics of the outbreaks ... -
Varroa destructor parasitism and genetic variability at honey bee (Apis mellifera) drone congregation areas and their associations with environmental variables in Argentina
(Frontiers Media, 2020-11)Varroa destructor is a serious ectoparasite of the western honey bee, Apis mellifera, which negatively impacts on colonies health and survival worldwide. Drone-mediated movement and the presence of the mite in Drone ... -
Vigilancia epidemiológica de tuberculosis : ¿Puede el engorde a corral brindar información adicional?
(Asociación Argentina de Veterinarios de Laboratorios de Diagnóstico, 2021)La tuberculosis bovina (TB) es una infección endémica en rodeos bovinos de Argentina. El movimiento de bovinos es un factor de riesgo para el ingreso de TB en rodeos de engorde (Milne et al., 2019). Sin embargo, esta es ... -
Vineyard environments influence Malbec grapevine phenotypic traits and DNA methylation patterns in a clone‑dependent way
(Springer Verlag, 2021-01)Clonal selection and vegetative propagation determine low genetic variability in grapevine cultivars, although it is common to observe diverse phenotypes. Environmental signals may induce epigenetic changes altering gene ... -
ViralPlaque: a Fiji macro for automated assessment of viral plaque statistics
(PeerJ, 2019-09)laque assay has been used for a long time to determine infectious titers and characterize prokaryotic and eukaryotic viruses forming plaques. Indeed, plaque morphology and dimensions can provide information regarding the ... -
Virulence characterization and identification of maize lines resistant to Puccinia sorghi Schwein. Present in the argentine corn belt region
(2016-04)Puccinia sorghi Schwein., the causal agent of maize common rust, is an endemic disease in the Argentine Corn Belt region. Virulence surveys of the pathogen population within the region have not been performed; thus, the ... -
Virulence factors of the Mycobacterium tuberculosis complex
(Taylor & Francis, 2013-01)The Mycobacterium tuberculosis complex (MTBC) consists of closely related species that cause tuberculosis in both humans and animals. This illness, still today, remains to be one of the leading causes of morbidity and ... -
Virulence genes and antimicrobial susceptibility in Salmonella enterica serotypes isolated from swine production in Argentina = Genes de virulencia y sensibilidad a antimicrobianos en serotipos de Salmonella enterica aislados de producción porcina en Argentina
(Elsevier, 2021)Salmonella is a worldwide-distributed pathogen that affects both humans and animals and is usually associated with intensive animal production such as poultry and swine. This bacterium carries different virulence genes, ... -
Virus infection elevates transcriptional activity of miR164a promoter in plants
(BioMed Central, 2009-12)Background: Micro RNAs (miRs) constitute a large group of endogenous small RNAs that have crucial roles in many important plant functions. Virus infection and transgenic expression of viral proteins alter accumulation and ... -
VP1 protein of Foot-and-mouth disease virus (FMDV) impairs baculovirus surface display
(Elsevier, 2013-07)The Foot-and-mouth disease virus (FMDV) causes important economical losses in livestock farming. In order to develop a novel subunit vaccine against FMDV, we constructed recombinant baculoviruses that display the protein ... -
Water deficit stress tolerance in maize conferred by expression of an anisopentenyltransferase (IPT) gene driven by a stress- and maturation-induced promoter
(2016)Senescence can be delayed in transgenic plants overexpressing the enzyme isopentenyltransferase (IPT) due to stress-induced increased levels of endogenous cytokinins. This trait leads to sustained photo-synthetic activity ... -
