Dependence of egg hatching on Wolbachia density in a parthenogenetic weevil revealed by antibiotic treatment
(Wiley, 2021-04)Naupactini is a tribe of Neotropical broad‐nosed weevils highly diverse in South America. This group includes several parthenogenetic species, some of them harmful for agriculture and invasive around the world. Although ... -
Development of a construct-based risk assessment framework for genetic engineered crops
(2016)Experience gained in the risk assessment (RA) of genetically engineered (GE) crops since their first experimental introductions in the early nineties, has increased the level of familiarity with these breeding methodologies ... -
Differences in sperm storage and remating propensity between adult females of two morphotypes of the Anastrepha fraterculus (Diptera: Tephritidae) cryptic species complex
(Cambridge University Press, 2014-06)The South American fruit fly, Anastrepha fraterculus, is a complex of cryptic species composed of at least seven morphotypes. Some of them, such as the Peruvian and Brazilian 1 morphotypes (which include Argentinean ... -
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 ... -
Dynamics of genetic variability in Anastrepha fraterculus (Diptera: Tephritidae) during adaptation to laboratory rearing conditions
(BioMed Central, 2014)Background: Anastrepha fraterculus is one of the most important fruit fly plagues in the American continent and only chemical control is applied in the field to diminish its population densities. A better understanding ... -
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 ... -
Effect of polyploidization in the production of essential oils in Lippia integrifolia
(2016-03)Consumption of medicinal and aromatic plants is widespread and increasing worldwide. Yet, harvesting from the wild, the main source of raw material in developing countries, is causing loss of genetic diversity and habitat ... -
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 ... -
Engineering Pseudomonas protegens Pf-5 for nitrogen fixation and its application to improve plant growth under nitrogen-deficient conditions
(2013-05-13)Nitrogen is the second most critical factor for crop production after water. In this study, the beneficial rhizobacterium Pseudomonas protegens Pf-5 was genetically modified to fix nitrogen using the genes encoding the ... -
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 ... -
Estudios regulatorios para las evaluaciones de riesgo de los cultivos transgénicos : un análisis preliminar
(Facultad de Agronomía, Universidad de Buenos Aires, 2022-06)Los desarrollos tecnológicos vinculados con los organismos genéticamente modificados (OGM) hicieron necesaria la implementación de sistemas regulatorios destinados a garantizar la seguridad ambiental y la aptitud alimentaria. ... -
European research priorities in farm animal genomics
(University of Zagreb, 2013-09)Production of safe and healthy high quality food for human population, preservation of stable rural social economic infrastructure and sustainable use of agricultural land and animal resources are important goals of European ... -
Evaluating mating compatibility within fruit fly cryptic species complexes and the potential role of sex pheromones in pre-mating isolation
(Pensoft Publishers, 2015-11)The study of sexual behavior and the identification of the signals involved in mate recognition between con-specifics are key components that can shed some light, as part of an integrative taxonomic approach, in delimitating ... -
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 ... -
Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases
(Springer, 2015-10)The vast majority of Pseudomonas species are unable to fix atmospheric nitrogen. Although several studies have demonstrated that some strains belonging to the genus Pseudomonas sensu stricto do have the ability to fix ... -
Exploring the Intrinsic Limits of Nitrogenase Transfer from Bacteria to Eukaryotes
(Springer, 2013-08)Biological nitrogen fixation is widespread among the Eubacteria and Archae domains but completely absent in eukaryotes. The lack of lateral transfer of nitrogen-fixation genes from prokaryotes to eukaryotes has been partially ... -
Expression analysis of genes putatively associated with hygienic behavior in selected stocks of Apis mellifera L. from Argentina
(2017-11)Hygienic behavior is an economically beneficial, heritable trait, which has evolved to limit the impact of honeybee pathogens. Selecting and breeding colonies with high levels of hygienic behavior has become a feasible and ... -
Fine mapping of LrSV2, a race-specific adult plant leaf rust resistance gene on wheat chromosome 3BS
(Springer, 2014-05)Three leaf rust resistance genes were identified in the durable leaf rust resistant Argentinean wheat variety Sinvalocho MA: the seedling resistance gene Lr3 on distal 6BL and two adult plant resistance genes, LrSV1 and ... -
Fruit infestation patterns by Anastrepha fraterculus and Ceratitis capitata reveal that cross-recognition does not lead to complete avoidance of interspecific competition in nature
(Wiley, 2015-08)1. The avoidance of parasitized or infested hosts, which is a common phenomenon in parasitic wasps and phytophagous insects, may act both intra- and interspecifically. Most studies on chemically-mediated avoidance of ...
