Aggressiveness of fusarium section liseola isolates causing maize ear rot in Argentina
(Edizioni ETS, 2010-03)Developing resistance to species of Fusarium in maize (Zea mays L.) is important to prevent field mycotoxin contamination. Isolates representative of natural conditions need to be identified to maximize selection responses. ... -
Expresión diferencial de genes involucrados en la resistencia de maíz (Zea mays L.) a Fusarium verticillioides, F. graminearum y Ustilago maydis
(2022-09)Las espigas de maíz (Zea mays L.) son afectadas por diversos patógenos que impactan negativamente sobre el rendimiento y la calidad de los granos. Entre los patógenos más relevantes que infectan este órgano, se destacan ... -
Identificación de regiones génicas candidatas para resistencia múltiple a enfermedades de espiga en maíz
(Asociación de Ingenieros Agrónomos del Norte de la Provincia de Buenos Aires, 2022-11)Maize ears are regularly infected with Fusarium verticillioides (FV), Fusarium graminearum (FG) and Ustilago maydis (UM), which causes reduction of grain yield and quality. However, conventional breeding can be hampered ... -
Map overlapping of QTL for resistance to Fusarium ear rot and associated traits in maize
(Springer, 2021-04)Mapping QTL for disease resistance and associated traits is important to develop maize (Zea mays L.) hybrids less susceptible to ear rots. A biparental mapping population of 298 F5 recombinant inbreds (RIs), obtained from ... -
Metaanálisis de transcriptomas de maíz (Zea Mays L.) en respuesta a fusarium verticillioides, f. graminearum y ustilago maydis
(Asociación de Ingenieros Agrónomos del Norte de la Provincia de Buenos Aires, 2022-11)Maize (Zea mays L.) ears are affected by several pathogens that impact grain yield and quality, such as Fusarium verticillioides (necrotroph), F. graminearum (hemibiotroph) and Ustilago maydis (biotroph). Even though there ... -
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 ... -
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 ... -
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 ... -
Severity of Fusarium ear rot and concentration of fumonisin in grain of Argentinian maize hybrids
(Elsevier, 2007-06)Fusarium ear rot severity and fumonisin concentration in grain of 16 Argentinian maize hybrids were assessed after inoculation with Fusarium verticillioides. Differences among hybrids for both traits indicate that field ... -
Volatile compounds released by maize grains and silks in response to infection by Fusarium verticillioides and its association with pathogen resistance
(2016)Many plants respond to fungal infections by producing and/or emitting a specific blend of oxylipins, some of them through the lipoxygenase (LOX) pathway. In vitro bioassays revealed that volatiles from silks and grains of ...
