(American Phytopathological Society, 2022-09-22)Scab, caused by the plant-pathogenic fungus Venturia effusa, is a major disease of pecan in South America, resulting in loss of quantity and quality of nut yield. Characteristics of the populations of V. effusa in South ... -
Precipitation is the main axis of tropical phylogenetic turnover across space and time
(BioRxiv, 2022-05-31)Early natural historians – Compte de Buffon, von Humboldt and De Candolle – established ecology and geography as two principal axes determining the distribution of groups of organisms, laying the foundations for biogeography ... -
Prediction of the extractives content of Eucalyptus globulus wood using NIRbased PLS-R models. Influence of spectral range and preprocessing on the percentage of outliers detected
(Taylor & Francis, 2022-07-08)Eucalyptus globulus is an important pulpwood source due to favorable wood characteristics, including low extractive content. However, there is significant tree-to-tree variation that can be exploited in breeding. This ... -
Preliminary report of the toxicity of Lippia junelliana (Lamiales: Verbenaceae) and Elionorus muticus (Poales: Poaceae) on Apis mellifera (Hymenoptera: Apidae)
(Sociedad Entomológica Argentina, 2022-01)Several phytochemicals, such as extracts and essential oils, are among the ecological alternatives that have been studied for the control of pathogens that affect humans, animals, and plants. Essential oils are aromatic ... -

(Sociedad Argentina de Botánica, 2015-09)En el presente trabajo se confirma formalmente la presencia de Mimosa regnellii y se cita por primera vez a M. regnellii var. exuta para la Flora Argentina. Esta especie y su variedad se distribuyen en el extremo oriental ... -
Primer Informe del Virus de la Papa Y en Calibrachoa Ornamental en Argentina
(2019-04-24)The identification of the calibrachoa-infecting PVY strain is vital for resistant-cultivar selection, and therefore it should be addressed in future studies. To our knowledge, this is the first report of PVY as a pathogen ... -
Primeros estudios cariotípicos en Mimosa farinosa y M. velloziana (Leguminosae, Mimosoideae)
(Instituto de Botánica del Nordeste, 2015)Se presentan los primeros estudios de cariotipo en Mimosa farinosa y M. velloziana. Se cita por primera vez el número cromosómico de M. farinosa, 2n = 2x = 26 (Mimosa sección Batocaulon serie Farinosae) y se confirma el ... -
Protocolo de fácil aplicación en la regeneración in vitro de "peperina" (Minthostachys verticillata) (Griseb) Epling)
(Universidad de Morón, 2021-10-14)La peperina es una especie aromática y medicinal que actualmente se encuentra sobreexplotada en su medio natural. El empleo del cultivo in vitro de tejido vegetal es una herramienta utilizada por varias disciplinas y en ... -
Quantitative genetic parameters for growth and wood properties in Eucalyptus “urograndis” hybrid using near-infrared phenotyping and genome-wide SNP-based relationships
(2019-06-24)A thorough understanding of the heritability, genetic correlations and additive and non-additive variance components of tree growth and wood properties is a requisite for effective tree breeding. This knowledge is essential ... -
Quantitative genetics and genomics converge to accelerate forest tree breeding
(2018-11)Forest tree breeding has been successful at delivering genetically improved material for multiple traits based on recurrent cycles of selection, mating, and testing. However, long breeding cycles, late flowering, variable ... -
Realistic scenarios of pesticide exposure alters multiple biomarkers in BOANA PULCHELLA (ANURA) Adult Frogs
(Springer, 2023-03-01)Imazethapyr, a post-emergent herbicide used in worldwide soybean and corn crops, induces genetic and biochemical alterations in aquatic vertebrates. This study examined the relationship between biomarkers at different ... -
Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescence
(2014-12)Background; During wheat senescence, leaf components are degraded in a coordinated manner, releasing amino acids and micronutrients which are subsequently transported to the developing grain. We have previously shown that ... -
Response to heat stress and glutenins allelic variation effects on quality traits in durum wheat
(Wiley, 2024-01-16)In the context of climate change, high temperature is one of the main abiotic stresses hampering durum wheat production. Through the characterization of an international panel of 271 genotypes, this study investigates the ... -
