(The American Phytopathological Society, 2024-04)Seedling diseases and root rot, caused by species of Fusarium, can limit soybean (Glycine max L.) production in the United States. Currently, there are few commercially available cultivars resistant to Fusarium. This study ... -
Nuevas líneas de soja con resistencia a roya asiática y búsqueda de nuevas fuentes de resistencia. Ciclo agrícola 2023/24
(Estación Experimental Agropecuaria Paraná, INTA, 2024)La virulencia de la roya asiática varía tanto anual y regionalmente como a nivel de cada lote de soja. Por lo tanto, los cultivares resistentes a la RAS deben estar adaptados a estas variaciones patogénicas del hongo. En ... -
The overexpression of antifungal genes enhances resistance to rhizoctonia solani in transgenic potato plants without affecting arbuscular mycorrhizal symbiosis
(Elsevier, 2019-10)The biological control of fungal diseases through the use of genetically modified (GM) plants could decrease the input of chemical pesticides. To overcome possible losses in potato (Solanum tuberosum) yield because of ... -
Overexpression of snakin-1 gene enhances resistance to Rhizoctonia solani and Erwinia carotovora in transgenic potato plants
(Wiley-Blackwell, 2008-05)Snakin‐1 (SN1), a cysteine‐rich peptide with broad‐spectrum antimicrobial activity in vitro, was evaluated for its ability to confer resistance to pathogens in transgenic potatoes. Genetic variants of this gene were cloned ... -
P0 protein of cotton leafroll dwarf virus-atypical isolate is a weak RNA silencing suppressor and the avirulence determinant that breaks the cotton Cbd gene-based resistance
(Wiley, 2019-08)Cotton blue disease (CBD) is the most important disease present in cotton crops in South America and cotton leafroll dwarf virus (CLRDV) is the causal agent. The disease has been controlled by sowing cotton varieties ... -
Parámetros genéticos, rendimiento y calidad forrajera en alfalfas (Medicago sativa L.) extremadamente sin reposo con expresión variable del carácter multifoliado obtenidas por selección fenotípica recurrente
(2015)La calidad nutricional de las plantas de alfalfa se correlaciona positivamente con la presencia de hojas multifolioladas (MF). Mediante selección fenotípica recurrente se desarrollaron poblaciones (Pob) extremadamente sin ... -
Peanut seed cultivars with contrasting resistance to Aspergillus parasiticus colonization display differential temporal response of protease inhibitors
(American Phytopathological Society, 2017-04)Significant efforts are being made to minimize aflatoxin contamination in peanut seeds and one possible strategy is to understand and exploit the mechanisms of plant defense against fungal infection. In this study we have ... -
Perfil sanitario de cultivares de trigo. Actualización 2023. Región pampeana-subregión pampa mesopotámica
(Estación Experimental Agropecuaria Paraná, INTA, 2023)Como productores, asesores y/o técnicos, podemos intervenir, directa e indirectamente, en el desarrollo de una enfermedad creando condiciones favorables o no para la misma. El principal método de control de royas y fusariosis ... -
Phenotyping sunflower genetic resources for Sclerotinia head rot response: assessing variability for disease resistance breeding
(The American Phytopathological Society, 2017-11)Sclerotinia head rot (SHR) is one of the most serious constraints to sunflower (Helianthus annuus L. var. macrocarpus) production worldwide. Here, we evaluated the response to SHR in a sunflower inbred panel from a large ... -
PLPKI: A novel serine protease inhibitor as a potential biochemical marker involved in horizontal resistance to Phytophthora infestans
(Wiley, 2014-04)Potato leaves infected with Phytophthora infestans produced a serine protease inhibitor (PLPKI) with specificity for microbial proteases. Sequencing of the first twenty residues at the NH2‐terminus of the mature PLPKI ... -
Las poblaciones locales de maíz como fuente para la resistencia a enfermedades
