Remating behavior in Anastrepha fraterculus (Diptera: Tephritidae) females is affected by male juvenile hormone analog treatment but not by male sterilization
(Cambridge University Press, 2013-06)The sterile insect technique (SIT) has been proposed as an area-wide method to control the South American fruit fly, Anastrepha fraterculus (Wiedemann). This technique requires sterilization, a procedure that affects, along ... -
Research gaps and new insights in the evolution of Drosophila seminal fluid proteins
(Wiley, 2021-11)While the striking effects of seminal fluid proteins (SFPs) on females are fairly conserved among Diptera, most SFPs lack detectable homologues among the SFP repertoires of phylogenetically distant species. How such a ... -
Response of the fruit fly parasitoid Diachasmimorpha longicaudata to host and host‐habitat volatile cues
(Wiley, 2012-05)Chemical information is crucial to insect parasitoids for successful host location. Here, we evaluated the innate response of Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), a fruit fly larval parasitoid, ... -
Root hydraulic conductivity and adjustments in stomatal conductance: hydraulic strategy in response to salt stress in a halotolerant species
(Oxford University Press, 2015-11)Recent advances at the molecular level are introducing a new scenario that needs to be integrated into the analysis of plant hydraulic properties. Although it is not yet clear to what extent this scenario alters the current ... -
The rpl23 gene and pseudogene are hotspots of illegitimate recombination in barley chloroplast mutator seedlings
(Nature Publishing Group, 2019-07)Previously, through a TILLING (Targeting Induced Local Lesions in Genomes) approach applied on barley chloroplast mutator (cpm) seedlings a high frequency of polymorphisms in the rpl23 gene was detected. All the polymorphisms ... -
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 ... -
Selective pressure against horizontally acquired prokaryotic genes as a driving force of plastid evolution
(Springer Nature, 2016-01)The plastid organelle comprises a high proportion of nucleus-encoded proteins that were acquired from different prokaryotic donors via independent horizontal gene transfers following its primary endosymbiotic origin. What ... -
Sex chromosomes in mitotic and polytene tissues of Anastrepha fraterculus (Diptera, Tephritidae) from Argentina: a review
(Pensoft Publishers, 2015-11)Cytogenetics, which is considered a fundamental tool to understand basic genetic and genomic issues of species, has greatly contributed to the description of polymorphisms both at inter- and intra-specific level. In fact, ... -
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 ... -
Silencing of the glutathione biosynthetic pathway inhibits somatic embryogenesis in wheat
(Springer, 2013-02)Somatic embryogenesis in scutella of wheat (Triticum aestivum L.) is a well documented phenomenon and it has been shown through transcriptome analysis that genes involved in antioxidant responses, particularly in glutathione ... -
Single nucleotide polymorphisms from candidate genes associated with nematode resistance and resilience in Corriedale and Pampinta sheep in Argentina
(Elsevier, 2021-02)Selective breeding of genetically resistant animals is considered a promising strategy to face the problem of nematode resistance to anthelmintics and mitigate concerns about the presence of chemical residues in animal ... -
Single nucleotide polymorphisms in candidate genes associated with milk yield in Argentinean Holstein and Holstein x Jersey cows
(2018-12)Research on loci influencing milk production traits of dairy cattle is one of the main topics of investigation in livestock. Many genomic regions and polymorphisms associated with dairy production have been reported ... -
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 ... -
Stable symbiotic nitrogen fixation under water-deficit field conditions by a stress-tolerant alfalfa microsymbiont and its complete genome sequence : Short communication
(2017-12)We here characterized the stress-tolerant alfalfa microsymbiont Sinorhizobium meliloti B401. B401-treated plants showed high nitrogen fixation rates under humid and semiarid environments. The production of glycine betaine ... -
Stress-induced expression of IPT gene in transgenic wheat reduces grain yield penalty under drought
(Springer, 2021-05)Background: The heterologous expression of isopentenyl transferase (IPT) under the transcriptional control of the senescence-associated receptor-like kinase (SARK) promoter delayed cellular senescence and, through it, ... -
Synthetic multi-antibiotic resistant plasmids in plant-associated bacteria from agricultural soils
(Elsevier, 2020-09)Objectives: Unlike higher organisms such as domestic animals and cultivated plants, which display a robust reproductive isolation and limited dispersal ability, microbes exhibit an extremely promiscuous gene flow and can ... -
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 ... -
Temporal changes in volatile profiles of Varroa destructor-infested brood may trigger hygienic behavior in Apis mellifera
(Wiley, 2021-03-16)Varroa destructor Anderson & Trueman (Acari: Varroidae) is one of the major contributors to the significant losses of western honey bee, Apis mellifera L. (Hymenoptera: Apidae), colonies worldwide. Hygienic behavior, in ... -
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 ... -
