Striking differences in the biological and molecular properties of onion and garlic isolates of onion yellow dwarf virus
(Springer, 2013-06)Complete nucleotide (nt) and deduced amino acid sequences of two onion yellow dwarf virus (OYDV) isolates showing mild and severe symptoms in onion but being unable to infect garlic were determined. The genomes consisted ... -
Structure and biological activities of lipochitooligosaccharide nodulation signals produced by Bradyrhizobium japonicum USDA 138 under saline and osmotic stress
(2014-02)The establishment of a symbiotic interaction involves a signal exchange between the host legume (flavonoids) and the nitrogen-fixing rhizobia (nodulation factors (NFs)). Likewise, abiotic stress conditions, such as salinity ... -

Sunflower
(Elsevier, 2023-09-22)Sunflower (Helianthus annuuss) is one of the oilseed crops most widely cultivated in the world. In 2019, world production amounted to more than 56 million tons (FAOSTAT, 2021). The crop is affected by several viral pathogens, ... -
Superoxide dismutase and glutathione reductase overexpression in wheat protoplast: photooxidative stress tolerance and changes in cellular redox state
(Springer, 2008-08-26)In previous works, we have established a correlation between antioxidant system response and tolerance to drought, osmotic stress and photooxidative stress of different wheat cultivars with contrasting drought tolerance. ... -
Supplementary datasets to the article "Botanical extracts for insect management: lessons from participatory research in the peri-urban horticultural systems of central Argentina" [Conjunto de datos]
(2024)Los datos corresponden a la evaluación de un extracto vegetal a base de ajo para el manejo de insectos en cultivo de lechuga en sistemas hortícolas convencionales y agroecológicos diversificados de la Región Agroalimentaria ... -
Suspected poisoning in beef cattle from ingestion of Prosopis nigra pods in north-western Argentina
(Elsevier, 2019-01)The aim of this paper was to present the first report of Prosopis nigra poisoning of cattle in Argentina. Outbreaks occurred in five farms located in Salta and Santiago del Estero provinces. All animals were examined, ... -
Sweet corn (Zea mays L.) growth and yield are influenced by establishment methods
(South African National Biodiversity Institute, 2014-06)Six experiments were performed in the term of three years in order to explore and compare the effects of transplanting and direct sowing (DS) on sweet corn (Zea mays L.) growth, earliness and yield. Different genotypes, ... -
Switching between monocot and dicot crops in rotation schemes of Argentinean productive fields results in an increment of arbuscular mycorrhizal fungi diversity
(2016-02)Despite the importance of mycorrhizal symbiosis, we understand little how different soil managements affect arbuscular mycorrhizal fungi (AMF) communities. Crop rotation is recommended in sustainable agriculture because ... -
Synthetic Communities of Bacterial Endophytes to Improve the Quality and Yield of Legume Crops
(IntechOpen, 2022-03-31)Plant-associated microbiomes confer fitness advantages to the plant host by growth promotion through different mechanisms including nutrient uptake, phytohormones production, resistance to pathogens, and stress tolerance. ... -
Teliosporas de Thecaphora frezii en semillas de maní (Arachis hypogaea)
(Asociación Argentina de Fitopatólogos, 2021-09-22)El carbón del maní, causado por Thecaphora frezii es el problema sanitario que mayor preocupación causa al sector manisero argentino Las teliosporas que provienen de vainas enfermas, se liberan durante el procesamiento en ... -
Temporal and spatial spread of potyvirus infection and its relationship to aphid populations visiting garlic crops
(Springer, 2014-11)The potyviruses Onion yellow dwarf virus (OYDV) and Leek yellow stripe virus (LYSV) are the main causes of serious losses in garlic crops worldwide. Both viruses are transmitted by aphid vectors in a non-persistent manner. ... -
