Identificación de cultivares de trébol blanco (trifolium repens l.) mediante SSR
(Sociedad Argentina de Genética, 2013-07)El trébol blanco (Trifolium repens L) es una leguminosa forrajera de gran valor nutritivo y muy eficiente en la incorporación de nitrógeno (N) al suelo mediante fijación simbiótica. En Argentina se ha difundido ampliamente ... -
Identification and characterization of Pythium graminicola, causal agent of kikuyu yellows in Argentina
(Springer, 2017-08)Kikuyu grass (Pennisetum clandestinum) is a perennial plant that belongs to the Poaceae family. In Argentina, it is used in warm areas as tropical pasture, forage and grass in gardens and sports fields. Species of Pythium ... -
Identification and characterization of soluble binding proteins associated with host foraging in the parasitoid wasp Diachasmimorpha longicaudata
(Plos, 2021-06)The communication and reproduction of insects are driven by chemical sensing. During this process, chemical compounds are transported across the sensillum lymph to the sensory neurons assisted by different types of soluble ... -
Identification of candidate genes associated with host-seeking behavior in the parasitoid wasp Diachasmimorpha longicaudata
(BioMed Central, 2024-02)Background: Diachasmimorpha longicaudata is a hymenopteran fruit fly endoparasitoid. Females of this species find their hosts for oviposition by using complex sensorial mechanisms in response to physical and chemical stimuli ... -
In vitro propagation of Lippia integrifolia (Griseb.) Hier. and detection of genetic instability through ISSR markers of in vitro-cultured plants.
(2016)Aromatic and medicinal plants have been traditionally harvested from the wild and, in Argentina, they have been exploited without any major limitation. In vitro plant propagation is an easy and inexpensive method to obtain ... -
In vivo and in vitro propagation of “macela”: a medicinal-aromatic native plant with ornamental potential
(Sociedade Brasileira de Floricultura e Plantas Ornmentais, 2018-12)Achyrocline satureioides is a shrub native from South America. In popular medicine it is used in infusions such as digestive, carminative, antispasmodic, eupeptic and emmenagogue. However, its main use is as an ingredient ... -
Individual precocity, temporal persistence, and task-specialization of hygienic bees from selected colonies of apis mellifera
(2016)Hygienic behaviour is a complex trait that gives Apis mellifera L. resistance against brood diseases. Variability in the expression of hygienic behaviour is evidenced at the colonylevel and is explained by the proportion ... -
Induced mutations in crop plants : mutants of scientific and/or agronomic interest at the Institute of Genetics “Ewald A. Favret” = Mutaciones inducidas en plantas cultivadas : mutantes de interés interés científico y/o agronómico en el Instituto de Genética “Ewald A. Favret”
(Universidad San Francisco de Quito, 2021-05)The use of induced mutations techniques in crop plants at Instituto de Genética "Ewald A. Favret" (IGEAF) INTA, started in 1949, with the pioneer work of Ewald Favret, who studied the effects of physical and chemical ... -
Infestation of fruit by conspecific and heterospecific females deters oviposition in two Tephritidae fruit fly species
(Wiley, 2020-09)Tephritidae fruit fly larvae develop entirely in the host chosen by the females. To improve the fitness of their progeny, females would benefit from rejecting previously exploited hosts. Anastrepha fraterculus and Ceratitis ... -
Innate Host Habitat Preference in the Parasitoid Diachasmimorpha longicaudata: Functional Significance and Modifications through Learning
(2016)Parasitoids searching for polyphagous herbivores can find their hosts in a variety of habitats. Under this scenario, chemical cues from the host habitat (not related to the host) represent poor indicators of host location. ... -
Lemon and Schinus polygama essential oils enhance male mating success of Anastrepha fraterculus
(Wiley, 2020-11-27)The sterile insect technique (SIT) is an environmentally friendly pest control method that relies on the introduction of sterility into the pest population by the release of sterile males. Many Tephritidae fruit fly pests ... -
LOV‐domain photoreceptor, encoded in a genomic island, attenuates the virulence of Pseudomonas syringae in light‐exposed Arabidopsis leaves
(Wiley, 2013-10)In Arabidopsis thaliana, light signals modulate the defences against bacteria. Here we show that light perceived by the LOV domain‐regulated two‐component system (Pst–Lov) of Pseudomonas syringae pv. tomato DC3000 (Pst ... -
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(2016)A main goal of biological nitrogen fixation research has been to expand the nitrogen-fixing ability to major cereal crops. In this work, we demonstrate the use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ... -
Male Sexual Behavior and Pheromone Emission Is Enhanced by Exposure to Guava Fruit Volatiles in Anastrepha fraterculus
(Plos One, 2015-04)Background: Plant chemicals can affect reproductive strategies of tephritid fruit flies by influencing sex pheromone communication and increasing male mating competitiveness. Objective and Methodology: We explored whether ... -
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 ... -
Mapping a gene on wheat chromosome 4BL involved in a complementary interaction with adult plant leaf rust resistance gene LrSV2
(Springer, 2018-08)A complementary gene to LrSV2 for specific adult plant leaf rust resistance in wheat was mapped on chromosome 4BL, tightly linked to Lr12 / 31. LrSV2 is a race-specific adult plant leaf rust (Puccinia triticina) resistance ... -
Mate choice confers direct benefits to females of Anastrepha fraterculus (Diptera: Tephritidae)
(Public Library of Science, 2019-06)Exposure to plant compounds and analogues of juvenile hormone (JH) increase male mating success in several species of tephritid fruit flies. Most of these species exhibit a lek mating system, characterized by active female ... -
Mating-induced changes in responses of female Queensland fruit fly to male pheromones and fruit : a mechanism for mating-induced sexual inhibition
(Elsevier, 2021-03)In order to reproduce, female tephritid fruit flies need both mates for fertilization and fruit for oviposition. Virgin females are prone to mating and approach males, attracted by their pheromones. Mated females, however, ... -
