No Common Candidate Genes for Resistance to Fusarium graminearum, F. proliferatum, F. sporotrichioides, and F. subglutanins in Soybean (Glycine max L.) Accessions from Maturity Groups 0 and I: Findings from Genome-Wide Association Mapping
(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 ... -
Occurrence and distribution of soil Fusarium species under wheat crop in zero tillage
(2013)The presence of Fusarium species in cultivated soils is commonly associated with plant debris and plant roots. Fusarium species are also soil saprophytes. The aim of this study was to examine the occurrence and distribution ... -
Pathogenicity of Fusarium graminearum and F. meridionale on soybean pod blight and trichothecene accumulation
(Wiley, 2016-12)Soybean (Glycine max) is the most important crop in Argentina. At present Fusarium graminearum is recognized as a primary pathogen of soybean in several countries in the Americas, mainly causing seed and root rot and pre‐ ... -
Phenylpropanoids from maize pericarp: resistance factors to kernel infection and fumonisin accumulation by Fusarium verticillioides
(Springer, 2013-01)The aim of this work was to investigate the role of pericarp phenylpropanoids as resistance factors to F. verticillioides in eleven maize genotypes. Disease severity and kernel fumonisin accumulation were measured after ... -
Presencia de zearalenona en pasturas del este de Chaco
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-04)Se estudió la presencia de zearalenona en pasturas y alimentos que son utilizados para la producción de bovinos de carne de la zona este de la provincia del Chaco. Asimismo, se realizó el aislamiento e identificación de ... -
Promotion of Lotus tenuis in the flooding Pampa (Argentina) increases the soil fungal diversity
(2018-06)Forage promotion is an increasingly used agricultural practice that requires herbicide application to remove competing plant species. This work examined the effect of the forage legume Lotus tenuis on the fungal community ... -
Quantitative trait loci for Fusarium and Gibberella ear rot resistance in Argentinian maize germplasm
(2016)Fusarium verticillioides and F. graminearum cause ear rots in maize (Zea mays L.) that reduce yield and contaminate the grain with mycotoxins produced by the fungi. To map QTLs for resistance to these ear rots, a F5 mapping ... -
