Evidence of cassava common mosaic virus in cassava shoot apical meristems
(Wiley, 2023-05-12)Cassava (Manihot esculenta) is an allogamous and highly heterozygous species. For this reason, its seeds are not used for production purposes (Ceballos & de la Cruz, 2002); instead, plantations are established using stem ... -
Evidence of Ehrlichia chaffeensis in Argentina through molecular detection in marsh deer (Blastocerus dichotomus)
(Elsevier, 2019-04)Vector-borne pathogens are responsible for serious emerging diseases and have been widely described in wildlife. Ehrlichia chaffeensis causes the zoonotic “monocytic ehrlichiosis” in humans, is transmitted by the tick ... -
Evidence of natural interspecific recombinant viruses between bovine alphaherpesviruses 1 and 5
(2017-10)Closely related bovine alphaherpesviruses 1 (BoHV-1) and 5 (BoHV-5) co-circulate in certain countries, rendering cattle co-infection possible. This is a prerequisite for BoHV recombination. Here, we report the first ... -
Evidence of porcine circovirus type 2 and co-infection with ungulate protoparvovirus 1 (porcine parvovirus) in mummies and stillborn piglets in subclinically infected farm
(Elsevier, 2021-04)Porcine circovirus type 2 (PCV2) and protoparvovirus 1 (PPV) were detected as single infection (6/131) and (11/131) respectively, or co-infection (6/131) in fetuses and stillborn piglets from normal deliveries in a farm ... -
Evidence of reduced vertical transmission of Neospora caninum associated with higher IgG1 than IgG2 serum levels and presence of IFN-γ in nonaborting chronically infected cattle under natural condition
(Elsevier, 2019-02)Neospora caninum infection of cattle can be vertically transmitted, resulting in abortion or birth of infected calves. Vertical transmission occurs both in acutely or chronically infected cattle. There is little information ... -
Evolución de la aptitud forrajera en híbridos de maíz (Zea mays L.): su relación con la producción de etanol
(Asociación de Ingenieros Agrónomos de la Zona Norte de la Provincia de Buenos Aires (AIANBA), 2018-08)Existe una estrecha relación entre la calidad del maíz forrajero y la producción de etanol. Los ensayos de calidad de los forrajes utilizados en la alimentación de los rumiantes podrían utilizarse como indicadores de la ... -
Evolución de la aptitud forrajera en híbridos de maíz: su relación con la producción de etanol
(Facultad de Ciencias Agrarias, Universidad Nacional de Lomas de Zamora, 2018)En Argentina, en los últimos años se incrementó la superficie sembrada de maíz, actualmente alcanza los 6,9 millones de hectáreas (Ministerio de Agroindustria), aumentando exponencialmente a partir de la campaña 2011/12, ... -
Evolución del mercado de herbicidas en Argentina
(Instituto de Ingeniería Rural, INTA, 2012-12)Dentro de la cadena de producción de agroalimentos el manejo integrado de plagas juega un rol preponderante, ya que asegura una cantidad y calidad económicamente aceptable del producto en cuestión. Si bien dentro de este ... -
Evolução da mancha preta do amendoim nas principais regiões produtoras da Argentina e do Brasil frente às mudanças no clima
(Universidade Federal de Pernambuco, 2020-06-11)A ocorrência da mancha preta do amendoim está diretamente relacionada aos elementos climáticos. Desta maneira, mapas de distribuição geográfica e temporal baseados em dados do clima contribuem com informações sobre o ... -
Evolution of pre‐zygotic and post‐zygotic barriers to gene flow among three cryptic species within the Anastrepha fraterculus complex
(Wiley, 2013-09)Tropical tephritids are ideally suited for studies on population divergence and speciation because they include species groups undergoing rapid radiation, in which morphologically cryptic species and sister species are ... -
Evolution of SARS-CoV-2 during the first year of the COVID-19 pandemic in Northwestern Argentina
(Elsevier, 2022-09-28)Studies about the evolution of SARS-CoV-2 lineages in different backgrounds such as naive populations are still scarce, especially from South America. This work aimed to study the introduction and diversification pattern ... -
Evolutionary insights into FYVE and PHOX effector proteins from the moss Physcomitrella patens
(Springer, 2020-02)Phosphatidylinositol 3-phosphate (PtdIns3P) is a signaling phospholipid, which regulates several aspects of plant growth and development, as well as responses to biotic and abiotic stresses. The mechanistic insights ... -
Examples of Risk Tools for Pests in Peanut (Arachis hypogaea) Developed for Five Countries Using Microsoft Excel
(Entomological Society of America, 2022-08-03)Suppressing pest populations below economically-damaging levels is an important element of sustainable peanut (Arachis hypogaea L.) production. Peanut farmers and their advisors often approach pest management with similar ... -
Exosomes Isolated from Ascites of T-Cell Lymphoma-Bearing Mice Expressing Surface CD24 and HSP-90 Induce a Tumor-Specific Immune Response
(2017-03-16)Extracellular vesicles (EVs), including endosome-derived nanovesicles (exosomes), are involved in cell–cell communication. Through transfer of their molecular contents, extracellular nanovesicles can alter the function of ... -
Expanding the benefits of Tnt1 for the identification of dominant mutations in polyploid crops: A single allelic mutation in the MsNAC39 gene produces multifoliated alfalfa
(Frontiers Media, 2022-04)Most major crops are polyploid species and the production of genetically engineered cultivars normally requires the introgression of transgenic or gene-edited traits into elite germplasm. Thus, a main goal of plant research ... -
