Influence of the time of fungicide application in the production of trichothecenes on field inoculated spikes from wheat grown in Argentina
(Springer, 2021-04-08)Fusarium graminearum is considered the main causative agent of Fusarium Head Blight in wheat. The fungus produces mycotoxins of the trichothecene family that pose a significant threat to the health of animals and humans. ... -
Influencia de las variedades de trigo y la aplicación de fungicidas en la producción de tricotecenos en cepas de Fusarium graminearum aisladas de trigo cultivado en Argentina
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2017-08)Fusarium graminearum (Schwabe) [teleomorfo Gibberella zeae (Schwein)] es considerado el principal agente causal de la Fusariosis de la espiga de trigo (FET) en Argentina. Se trata de una enfermedad floral, pues el proceso ... -
Mal de Río Cuarto virus infection causes hormone imbalance and sugar accumulation in wheat leaves
(BMC, 2019-03)Background; Mal de Río Cuarto virus (MRCV) infects several monocotyledonous species including maize and wheat. Infected plants show shortened internodes, partial sterility, increased tillering and reduced root length. To ... -
Mal de Río Cuarto Virus infection triggers the production of distinctive viral-derived siRNA profiles in wheat and Its planthopper vector
(2017)Plant reoviruses are able to multiply in gramineae plants and delphacid vectors encountering different defense strategies with unique features. This study aims to comparatively assess alterations of small RNA (sRNA) ... -
Manipulation of the post-flowering source/sink ratio differentially affects protein composition and gluten quality in contrasting bread wheat genotypes
(Elsevier, 2024-03-28)Studies of the impact of assimilate availability during grain filling on protein composition and gluten quality of bread wheat are scarce. Therefore, this work aimed to analyze the responses of wet gluten percentage, SDS ... -
