A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
Array comparative genomic hybridization in confirmation of the deleted genes in a patient with subterminal deletion of the long arm of chromosome 10 associated with sagittal craniosynostosis and dysmorphic features
(BioMed Central, 2014)Craniosynostosis results from premature ossification of one or more cranial sutures and leads to alterations in the shape of the skull and/or premature closure of cranial fontanels, causing impairment of brain ... -
Caracterización de la variabilidad genética de colonias comerciales y silvestres de Apis mellifera en Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2018-09)La abeja doméstica o abeja melífera, Apis mellifera (Linnaeus, 1758) , es un insecto social perteneciente al orden Hymenoptera, familia Apidae. Esta especie está estrechamente relacionada con la actividad humana a través ... -
Chromosome studies in southern species of Mimosa (Fabaceae, Mimosoideae) and their taxonomic and evolutionary inferences
(2014-05)In this work, chromosome numbers and karyotype parameters of 36 taxa of the genus Mimosa were studied, especially from the southern South America center of diversification. Results support that x = 13 is the basic chromosome ... -
Comportamiento de híbridos de maíz para ensilaje y grano a roya común en siembra temprana. Ciclo agrícola 2021/22
(Estación Experimental Agropecuaria Paraná, INTA, 2022-08)El objetivo del trabajo consiste en evaluar el comportamiento de híbridos de maíz con aptitud para ensilaje y grano frente a la roya común (Puccinia sorghi) en siembra temprana, en Paraná, Entre Ríos. -
Crop-wild sunflower hybridization can mediate weediness throughout growth-stress tolerance trade-offs
(2017-11)Agricultural weeds are plants well-adapted to agricultural environments interfering directly and indirectly with crop production and causing important economic losses worldwide. Crop-wild hybridization is one of the main ... -
Cytogenetic evidence of hybridization in Prosopis alba, P. hassleri, and P. fiebrigii in the semiarid-humid Chaco transition
(Taylor and Francis, 2023-06-06)Hybridization is a common and widespread phenomenon in vascular plants, leading to genetic exchange between related species. Interspecific hybridization has been extensively reported in Prosopis, a key genus of the Gran ... -
Development of a non-radioactive molecular hybridization probe for detecting Strawberry mottle virus in strawberry
(2016)The vegetative propagation of strawberries favors transmission of systemic pathogens, such as viruses, which are one of the main yield-limiting factors for this crop. More than 20 viruses have been described as infecting ... -
Development of genomic resources for Nothofagus species using next‐generation sequencing data
(Wiley, 2014-11)Using next‐generation sequencing, we developed the first whole‐genome resources for two hybridizing Nothofagus species of the Patagonian forests that crucially lack genomic data, despite their ecological and industrial ... -
Do parapatric populations of the ticks Amblyomma tonelliae Nava, Beati & Labruna, 2014 and Amblyomma sculptum Berlese, 1888 (Acari: Ixodidae) hybridize?
(Royal Entomological Society, 2023-02-02)This work aimed to determine if the tick species, Amblyomma sculptum and Amblyomma tonelliae, hybridize along their contact zones in Argentina. Free-living adults and nymphs of A. sculptum and A. tonelliae were collected ... -
Drought stress tolerance of Prosopis chilensis and Prosopis flexuosa species and their hybrids
(Springer, 2013-02)Natural hybridization commonly produces individuals with intermediate morphological and genetic characteristics, but their response to environmental stress is still uncertain, with some studies showing that transgressive ... -
Epidemiology of Babesia, Anaplasma and Trypanosoma species using a new expanded reverse line blot hybridization assay
(2018-02)Vector-borne hemoparasitic infections are a major problem that affects livestock industries worldwide, particularly in tropical and subtropical regions. In this work, a reverse line blot (RLB) hybridization assay was ... -
Genetic and morphometric markers are able to differentiate three morphotypes belonging to Section Algarobia of genus Prosopis (Leguminosae, Mimosoideae)
(Springer, 2013-06)The section Algarobia of genus Prosopis includes promising species for reforestation and afforestation programmes in arid and semiarid regions, mainly of the Americas. Many interspecific natural hybrid combinations have ... -
