Male–female separation with a genetic sexing strain of Medfly, Ceratitis capitata, based on the gene sw (slow)
(lsteg Scientific Publications, 2004)The rate of development of the Medfly, Ceratitis capitata, slows down in the presence of mutation slow, sw. Separation of fast-developing males from slow-developing females is possible when this locus on chromosome 2 is ... -

Caracterización molecular de mutantes derivadas del genotipo mutador de cloroplastos de cebada
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2008)La coordinación de la expresión génica entre los genomas nuclear, plastídico y mitocondrial es de importancia crucial para las células vegetales. Un caso particular de la interacción núcleo-plástido está dado por los genes ... -
PCR identification of petunia male sterile cytoplasm = Identificação por PCR de citoplasma macho estéril em Petunia
(Sociedade Brasileira de Floricultura e Plantas Ornamentais, 2019-12)Petunia is a very important ornamental plant with a broad range of flower colour and size, and most of the cultivars grown are propagated through seeds. Cytoplasmic male sterility (CMS) is a maternally inherited character ... -
The ammonium channel NOD26 is the evolutionary innovation that drives the emergence, consolidation, and dissemination of nitrogen-fixing symbiosis in angiosperms
(Springer, 2018-10)Increasing evidence indicates that N-fixing symbiosis has evolved several times in the N-fixing clade of angiosperms and that this evolution is driven by a single evolutionary innovation. However, the genetics of this ... -
Understanding the intracellular-to-extracellular localization switch of polyhydroxybutyrate polymerase in pseudomonas backgrounds as a microevolutionary process
(Elsevier, 2018-11)After gene duplication, paralogous genes evolve independently, and consequently, the new proteins encoded by these duplicated genes are exposed to changes in their subcellular location. Although there are increasing evidence ... -
Shortening of generation cycles in inbred lines of maize (Zea mays L.) through embryo rescue technique
(Istituto Sperimentale per la Cerealicoltura, 2019-11)Embryo rescue techniques have been used as an approach to raise hybrids from incompatible crosses. These techniques have also proved to be valuable tools for maize improvement, since they allow reducing the duration of the ... -
Generalized glycogenosis in Brahman-derived breeds: diagnosis and prevalence in Argentina
(Springer, 2019-08)Generalized glycogenosis is a lethal autosomal recessive disease caused by a deficient activity of the acidic 1,4-α-glucosidase enzyme and characterized by an accumulation of glycogen within lysosomes. Three mutations in ... -
Caracterización taxonómica y análisis de la variabilidad del agente causal del cancro del tallo de la soja en Buenos Aires (2005/2007)
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-12)El complejo Diaporthe/Phomopsis es un importante grupo de hongos patógenos de la soja. Dentro del mismo, Diaporthe phaseolorum var. caulivora es uno de los agentes causales del cancro del tallo. Veintitrés aislamientos de ... -
Aplicación de técnicas no convencionales para la obtención de variabilidad genética en Panicum maximum Jacq.
(Universidad Nacional de Luján, 2016)En los últimos años el incremento de la agricultura provocó un reordenamiento territorial de la ganadería hacia regiones extrapampeanas con ambientes más restrictivos. El “Gatton Panic” (Panicum maximum Jacq. cv. Gatton) ... -
Estudio de la variabilidad genética inducida por el genotipo mutador de cloroplastos de la cebada a través de la técnica de TILLING
(Departamento de Fisiología, Biología Molecular y Celular, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2018-11)El aislamiento de mutantes inducidas en el plastoma a partir de tratamientos con mutágenos químicos y/o físicos es muy poco exitoso. El genotipo mutador de los cloroplastos de la cebada (cpm) es único en monocotiledóneas ... -
Taking advantage og organelle genomes in plant breeding: an integrated approach = Aprovechando los genomas de las organelas en el mejoramiento genético de plantas: un enfoque integrado
(Sociedad Argentina de Genética, 2019-07)Plant cells carry their genetic information in three compartments: the nucleus, the plastids and the mitochondria. In last years, next-generation sequencing has allowed the development of genomic databases, which are ... -
