Estructura genética de poblaciones de Phytophthora capsici en el noreste de la provincia de Buenos Aires, Argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-04)Phytophthora capsici causa enfermedades destructivas en todo el mundo. El patógeno es heterotálico y los dos tipos de apareamiento (TAs) son requeridos para la reproducción sexual. La razón de TAs varía entre regiones ... -
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 ... -
Análisis composicional cuanti-cualitativo de los macronutrientes del grano de híbridos de maíz con valor mejorado (VEC) desarrollados para la industria alimentaria argentina
(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 ... -
Science based criteria for a simplified risk assessment of genetic engineered crops developed using identical or similar constructs
(2016-08)Experience with Agricultural Biotechnology and the widespread adoption of different genetically engineered (GE) crops around the world has enabled breeders to develop different crops with similar phenotypic characteristics ... -
Effect of butanol and salt concentration on solid-state nanopores resistance
(Taylor & Francis, 2016-09)The objective of this study was to demonstrate the possibility of using 1-butanol to reliably detect the open-pore current of pyramidal solid-state nanopores produced in silicon wafers. The nanopores were produced through ... -
Spermatogenesis in the parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae)
(2017)The study of spermatogenesis in Hymenoptera is limited to few taxa due to limitations to access the material in the right stage for analysis. The information available up to now states that the gametogenesis in males ... -
Effects of superparasitism on immature and adult stages of Diachasmimorpha longicaudata Ashmead (Hymenoptera: Braconidae) reared on Ceratitis capitata Wiedemann (Diptera: Tephritidae)
(2017)The optimal use of available host by parasitoid insects should be favoured by natural selection. For solitary parasitoids, superparasitism (i.e. the egg-laying of several eggs/host) may represent a detrimental phenomenon ... -
The use of genetic, manual and chemical methods to control pollination in vegetable hybrid seed production : a review
(2017)Production of hybrid varieties of vegetable crops is currently a desired breeding goal, due to their remarkable agronomic performance and to the possibility of intellectual property protection. However, efficient hybrid ... -
Male sexual enhancement after methoprene treatment in Anastrepha fraterculus (Diptera: Tephritidae) : a sustained response that does not fade away after sexual maturation
(2017)The juvenile hormone (JH) of insects triggers physiological changes related to reproduction in adults of both sexes. Methoprene is a sesquiterpene with some effects that are analogous to those of JH. Treatments with ... -
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 ... -
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 ... -
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 ... -
Discriminación genotípica de serovariedades del serogrupo Icterohaemorrhagiae pertenecientes a Leptospira interrogans (Spirochaetales: Leptospiraceae) y el análisis de distancias génicas mediante coordenadas principales
(2017-01-18)La leptospirosis es una zoonosis de amplia distribución mundial y de importancia en salud pública y veterinaria. El serogrupo Icterohaemorrhagiae toma importancia, ya que ha sido aislado con frecuencia en roedores y en ... -
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 ... -
Genetic entanglement between Cercospora species associating soybean purple seed stain
(2017-06)Soybean purple seed stain (S-PSS) is a destructive, worldwide distributed fungal disease caused by several Cercospora species. This work aims to shed light on the nature of the genealogical and genetic relationships amongst ... -
Genome-wide identification of the mutation uderlying fleece variation and discriminating ancestral hairy species from modern woolly sheep
(Oxford university press, 2017-07)The composition and structure of fleece variation observedin mammals is a consequence of a strong selective pressure for fiber production after domestication. In sheep, fleece variation discriminates ancestral species ... -
Microevolution rather than large genome divergence determines the effectiveness of legume–rhizobia symbiotic interaction under field conditions
(2017-08)Despite the vast screening for natural nitrogenfixing isolates by public and private consortia, no significant progresses in the production of improved nitrogenfixing inoculants for alfalfa production have been made in the ... -
