A comet assay protocol for analysis of DNA damage in cryopreserved nuclei from Arabidopsis seeds, seedlings, and leaves
(Elsevier, 2025-12)The comet assay is classically applied to study DNA damage at the single-cell level. In plants, it is commonly used for the analysis of seedlings, leaves, and seeds. The assay is time-consuming and runs continuously, making ... -
Presence of Dalbulus maidis (Hemiptera: Cicadellidae) and of Spiroplasma kunkelii in the Temperate Region of Argentina
(Oxford University Press, 2013-08-01)“Corn stunt” is one of the main corn (Zea mays L.) diseases in the Americas and Dalbulus maidis (DeLong & Wolcott) is the key vector of the pathogen Spiroplasma kunkelii Whitcomb. In Argentina, the corn-producing area is ... -
Exitianus obscurinervis (Hemiptera: Cicadellidae), a New Experimental Vector of Spiroplasma kunkelii
(Oxford University Press, 2011-12-01)“Corn stunt” caused by the mollicute Spiroplasma kunkelii (Whitcomb) is potentially one of the most severe diseases affecting the corn (Zea mays L.) crop in the Americas, and the leafhopper Dalbulus maidis (DeLong & Wolcott) ... -
What can we learn from the ecophysiology of plants inhabiting extreme environments? From ‘sherplants’ to ‘shercrops’
(Oxford University Press, 2025-05-29)In the 19th century it was proposed that ecophysiology was best studied in regions with extreme climatic conditions. In the present perspective, we argue that perhaps this is more timely than ever. The main reason is the ... -
Neutral and adaptive genetic diversity in Neltuma alba (Leguminosae), an emblematic species of the Dry Chaco Forest
(Oxford University Press, 2025-08-11)Dry forests, characterized by seasonal rainfall, are exposed to prolonged drought periods and high temperatures throughout the year, with the consequent restricted water availability. Organisms occurring in these environments ... -
Agrobiodiversity and associated trophic interactions as an indicator of sustainability in 73 productive systems of Argentine Pampeana Region
(Universidad de Murcia; Sociedad Española de Agricultura Ecológica, 2024-05-24)Biodiversity is crucial in agroecosystems, as it makes them more efficient, stronger, productive and resilient. The aim was to determine and compare the existing biodiversity in two different production systems: agroecological ... -
Nationwide native forest structure maps for Argentina based on forest inventory data, SAR Sentinel-1 and vegetation metrics from Sentinel-2 imagery
(Elsevier, 2023-02-01)Detailed maps of forest structure attributes are crucial for sustainable forest management, conservation, and forest ecosystem science at the landscape level. Mapping the structure of broad heterogeneous forests is ... -
Employing scientific evidence through synthetic indices to support management and conservation policies for an endangered tree of the Gran Chaco
(Elsevier, 2024-09)Management and conservation programs require accessible scientific evidence to effectively plan and achieve their goals. Facing regional and species-specific threats, Gonopterodendron sarmientoi, an endangered tree native ... -
In vitro micrografting as an innovative strategy for the vegetative propagation of algarrobo blanco (Neltuma alba)
(Springer, 2025-05-28)Neltuma alba (Formerly Prosopis alba), known as ‘algarrobo blanco,’ is a native species of great biological, productive, and cultural importance in the phytogeographic regions of the Gran Chaco and the Espinal. However, ... -
Diversidad intravarietal del cv. Manzanilla de olivo (Olea europaea L.) y genotipos selectos relacionados de la colección INTA Catamarca y huertos de Cruz del Eje, Córdoba (Argentina) = Intravarietal diversity of Manzanilla Olive cultivar (Olea europaea L.) and related selected genotypes from the INTA Catamarca collection and orchards of Cruz del Eje, Córdoba (Argentina)
(Universidad Nacional de Córdoba, 2021-08)RESUMEN El olivo (Olea europaea L.) presenta un complejo panorama varietal aún no caracterizado e identificado totalmente. En este trabajo se estudió material con incertidumbre identitaria: se analizaron seis loci ... -
Editorial: Pathogen suppression by plant-associated microbiota
(Frontiers Media, 2025-04-14)Plants interact with a broad spectrum of microorganisms, including non-pathogenic microbes, which play a crucial role in plant health, productivity, and stress resilience. While pathogens have been widely studied due to ... -
Unraveling resilience amidst degradation: Recurring loss of freshwater marshes in the Paraná River Delta, Argentina
(Elsevier, 2024-11)Wetland ecosystems have experienced several ecological and hydrological impacts in recent decades determined by human activities and natural disturbances. The Lower Delta of the Paraná River, one of the most important ... -
Nitric oxide participates in sucrose–TOR signaling during meristem activation in Arabidopsis thaliana
(Springer, 2024-10)Nitric oxide (NO) constitutes a signal molecule that regulates important target proteins related to growth and development and also contributes to metabolic reprogramming that occurs under adverse conditions. Taking into ... -

(Universidad Nacional de Misiones. Facultad de Ciencias Exactas, Químicas y Naturales. Secretaria de Investigación y Posgrado, 2021)Resumen El objetivo del presente trabajo fue determinar el valor del coeficiente de dispersión longitudinal (DL) del arroyo Chicamtoltina (Alta Gracia) por medio de dos técnicas diferentes, a fin de comparar los valores ... -
Genetic and climatic approaches reveal effects of Pleistocene refugia and climatic stability in an old giant of the Neotropical Dry Forest
(Oxford University Press, 2018-07)Neotropical Dry Forests are important biodiversity hotspots characterized by intermediate to high levels of species richness and endemism. A possible explanation for these characteristics is that such forests have been ... -
Redox regulation of autophagy in Arabidopsis: The different ROS effects
