Exploring the cooperation between nitrogen-fixing and non-fixing alfalfa rhizobia
(Springer, 2024-07-05)Alfalfa plays a crucial role in agriculture due to its nitrogen-fixing partnership with rhizobia, resulting in nutritious forage. While the potential parasitic action of inefficient rhizobia has been extensively studied, ... -
Exploring the factors involved in the absence of parasitism of Chaetosiphon fragaefolii by generalist parasitoids in strawberry
(Springer, 2020-08)Chaetosiphon fragaefolii Cockerell (Hemiptera: Aphididae) is a worldwide strawberry pest with scarce records of parasitoids for its control. The parasitization rate of two generalist parasitoids, Aphidius colemani Viereck ... -

(2014-10-16)Yerba mate (Ilex paraguariensis A. St.-Hil.) is an important subtropical tree crop cultivated on 326,000 ha in Argentina, Brazil and Paraguay, with a total yield production of more than 1,000,000 t. Yerba mate presents a ... -
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 ... -
Exploring the role of the NO‑detoxifying enzyme HmpA in the evolution of domesticated Alfalfa Rhizobia
(Springer, 2022-02)We have previously shown the extensive loss of genes during the domestication of alfalfa rhizobia and the high nitrous oxide emission associated with the extreme genomic instability of commercial inoculants. In the present ... -
Exploring the tymovirales landscape through metatranscriptomics data
(Springer, 2022-06-16)Tymovirales is an order of viruses with positive-sense RNA genomes that mostly infect plants, but also fungi and insects. The number of genome sequences of viruses that could fit this taxon has been growing in the last few ... -
Exposure of Nonbreeding Migratory Shorebirds to Cholinesterase Inhibiting Contaminants in the Western Hemisphere
(Oxford Academic Press, 2010-02)Migratory shorebirds frequently forage and roost in agricultural habitats, where they may be exposed to cholinesterase-inhibiting pesticides. Exposure to organophosphorus and carbamate compounds, common anti-cholinesterases, ... -
Expresión de antígenos derivados del virus de la fiebre aftosa en diferentes sistemas eucarióticos
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2000)La fiebre aftosa es una enfermedad de gran importancia económica que afecta principalmente al ganado bovino. Esta enfermedad está causada por un picornavirus, el virus de la fiebre aftosa (VFA). El control de la enfermedad ... -
Expresión heteróloga y localización subcelular del candidato vacunal GPI4 de babesia bovis en el ciliado tetrahymena thermophila
(FundaVet, 2019-06)Los glicosilfosfatidilinositoles (GPIs) se encuentran en abundancia en la superficie de protozoos parásitos como glicolípidos libres y como anclas de proteínas de superficie a la membrana plasmática. Se ha demostrado que ... -
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 ... -
Expression of animal anti-apoptotic gene ced-9 enhances tolerance during Glycine max L.– Bradyrhizobium japonicum interaction under saline stress but reduces nodule formation
(2014-07-27)The mechanisms by which the expression of animal cell death suppressors in economically important plants conferred enhanced stress tolerance are not fully understood. In the present work, the effect of expression of animal ... -
Expression-based analysis of genes related to single nucleotide polymorphism hits associated with bovine leukemia virus proviral load in Argentinean dairy cattle
(Elsevier, 2021-02)In dairy cattle infected with bovine leukemia virus (BLV), the proviral load (PVL) level is directly related to the viral transmission from infected animals to their healthy herdmates. Two contrasting phenotypic groups can ... -
Extending Grime’s CSR model to predict plant demographic responses across resource availability gradients: evidence from the patagonian steppes
(Wiley, 2024-04-15)Sexual reproduction, growth, and survival are crucial demographic strategies for plant population viability. Here, we propose a conceptual model predicting demographic responses of species based on their ecological ... -

Extrapolation of a structural equation model for digital soil mapping
(Elsevier, 2020-05)In theory, two separate regions with the same soil-forming factors should develop similar soil conditions. This theoretical finding has been used in digital soil mapping (DSM) to extrapolate a model from one area to another, ... -
