A novel association of BoLA DRB3 alleles in BLV infected cattle with different proviral loads
(2017)Bovine leukemia virus (BLV) is associated with the most common neoplastic disease of cattle. BLV has a silent dissemination in the herd due to infected cell exchange, thus the concentration of BLV-infected cells in blood ... -
A novel source of cytoplasmic male sterility in Calibrachoa pubescens
(2017)Calibrachoa pubescens is a species native from the south of Brazil, Uruguay and northeast Argentina. An accession identified as 7.3.1.1 was collected at San Martín Department in Corrientes Province, Argentina and is included ... -
Absence of the nitrous oxide reductase gene cluster in commercial alfalfa inoculants is probably due to the extensive loss of genes during rhizobial domestication
(Springer, 2018-08)As other legume crops, alfalfa cultivation increases the emission of the greenhouse gas nitrous oxide (N2O). Since legumesymbiotic nitrogen-fixing bacteria play a crucial role in this emission, it is important to understand ... -
Adh1 first intron polymorphisms in Argentinean populations of Ceratitis capitata
(2010-07)DNA size polymorphisms were utilized in a study of 24 natural populations of Ceratitis capitata Wiedemann (Diptera: Tephritidae) from Argentina. The first intron of alcohol dehydrogenase 1 gene (Adh1) was amplified using ... -
Alfalfa snakin-1 prevents fungal colonization and probably coevolved with rhizobia
(BMC Plant Biology, 2014-09-17)Background: The production of antimicrobial peptides is a common defense strategy of living cells against a wide range of pathogens. Plant snakin peptides inhibit bacterial and fungal growth at extremely low concentrations. ... -
An isopentenyl transferase transgenic wheat isoline exhibits less seminal root growth impairment and a differential metabolite profile under Cd stress
(Wiley, 2021-09)Cadmium is one of the most important contaminants and it induces severe plant growth restriction. In this study, we analyzed the metabolic changes associated with root growth restriction caused by cadmium in the early ... -

(2016-06)El objetivo de este trabajo ha sido determinar la calidad química del grano y de las harinas y aceites obtenidos de diferentes híbridos de maíz con valor mejorado. Entre 20012/13 a 2014/15 se condujeron ensayos de campo ... -
Ancestry analysis of locally adapted crespa goats from southernmost Brazil
(2016)Crespa goats are phenotypically similar to the Angora breed, and are traditionally reared in small, low-tech farms in southernmost Brazil. Whether they represent degenerated remnants of pure Angora goats or result from ... -
Una aplicación política para la enseñanza de la teoría de juegos = A political application for the teaching of game theory
(Universidad de Morón, 2020-11)La contribución de la teoría de juegos a diferentes conflictos ha resultado relevante. Uno de los principales aspectos es el conflicto político. Se presenta un ejemplo relacionado con un conflicto político que ha existido ... -
Aportes a la Técnica de Insecto Estéril: Una cepa de Anastrepha fraterculus (Diptera: Tephritidae) con maduración sexual temprana
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)El proceso de maduración sexual de los machos de Anastrepha fraterculus (Wied.) es relativamente largo comparado con el de otros tefrítidos. Si se quiere aplicar la Técnica del Insecto Estéril (TIE), el costo se incrementa ... -
Argentina’s local crop biotechnology developments: why have they not reached the market yet?
(Frontiers Media, 2020-04)Plant biotechnology in Argentina started at the end of the 1980s, leading to the development of numerous research groups in public institutions and, a decade later, to some local private initiatives. The numerous scientific ... -
Association of TNF-α gene promoter region polymorphisms in bovine leukemia virus (BLV)-infected cattle with different proviral loads
(2015-08)Tumor necrosis factor alpha (TNF-α) is a pleiotropic cytokine involved in the immune response against viral and other infections. Its expression levels are affected by a polymorphism in the promoter region of the gene. ... -
Beyond arabidopsis: differential UV-B response mediated by UVR8 in diverse species
(Frontiers Media, 2019-06)Ultraviolet-B radiation (UV-B, 280–315 nm) is an important environmental signal that regulates growth and development in plants. Two dose-dependent UV-B response pathways were described in plants: a specific one, mediated ... -
BOLA-DRB3 gene polymorphisms influence bovine leukaemia virus infection levels in Holstein and Holstein × Jersey crossbreed dairy cattle
(2017-05)Bovine leukemia virus (BLV) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter-individual variation in the level of ... -
Bovine leukemia virus becomes established in dairy herds before the first lactation
(2016)In this work, we studied seven groups of pregnant heifers from a consortium of dairy farms heavily infected with bovine leukemia virus (BLV). ELISA testing showed that the seroprevalence ranges of BLV in heifers between ... -
Canarypox virus expressing infectious bursal disease VP2 protein as immunogen for chickens
(Sociedade Brasileira de Microbiologia, 2014-05)Canarypox viruses (CNPV) carrying the coding sequence of VP2 protein from infectious bursal disease virus (IBDV) were obtained. These viruses were able to express VP2 protein in vitro and to induce IBDV-neutralizing ... -
