A fungal endophyte of a palatable grass affects preference of large herbivores
(2018-04)Temperate grasses frequently acquire resistance to herbivores through a symbiosis with epichloid fungi that produces alkaloids of variable deterrent effects. However, in those cases without apparent endophyte negative ... -
Aislamientos de endófitos en nódulos de alfalfa en haplustoles salinos
(Asociación Argentina de la Ciencia del Suelo, 2022-11-15)El objetivo de este trabajo fue describir la diversidad de endófitos aislados de nódulos de alfalfa según la posición de las plantas en el paisaje y de los nóludos en el perfil del suelo y su relación con algunas propiedades ... -
Assessment of bacterial inoculant formulated with Paraburkholderia tropica to enhance wheat productivity
(2018-06)Paraburkholderia tropica is an endophytic nitrogen-fixing bacterium isolated from the rhizosphere, rhizoplane, and internal tissues of sugarcane and corn plants in different geographical regions. Other plant-growth-promoting ... -
Bacillus thuringiensis and their endophytic capabilities
(2017-07)The main characteristic of Bacillus thuringiensis is that during sporulation produces a parasporal inclusion formed by one or more proteinaceous bodies that exhibit insecticidal activity upon ingestion by susceptible ... -
A bacterial endophyte from apoplast fluids protects canola plants from different phytopathogens via antibiosis and induction of host resistance
(American Phytopathological Society, 2019-03)Endophytic bacteria colonize inner plant tissues and thrive at the apoplast, which is considered its main reservoir. Because this niche is the place where the main molecular events take place between beneficial and pathogenic ... -
Beneficial effects of Neotyphodium tembladerae and Neotyphodium pampeanum on a wild forage grass
(Wiley, 2012-09)Asexual, vertically transmitted fungal endophytes of the genus Neotyphodium are considered to enhance growth, stress resistance and competitiveness of agronomic grasses, but have been suggested to have neutral or deleterious ... -
Effect of epichloid endophytes and soil fertilization on arbuscular mycorrhizal colonization of a wild grass
(2016-08)Background and aims: Plants often establish multiple simultaneous symbiotic associations with different micro-organisms; however, the way in which each symbiont affects the other symbionts and the effects of these multiple ... -
Endophytes of native grasses from South America: biodiversity and ecology
(Elsevier, 2012-06)We review and present preliminary results of studies on cool-season grass endophytes native to South America. These fungi have been studied only in Argentina, where they have been detected in 36 native grass species. The ... -

Hongos endófitos en festuca alta: del problema a las soluciones
(Ediciones INTA, 2019-08)Festuca alta, Schedonorus arundinaceus (Schreb.) Dumort, es una de las gramíneas perennes templadas más sembradas en Argentina, tanto en pasturas puras como en mezclas. Entre las principales cualidades agronómicas de esta ... -
Identificación de bacterias endófitas con efecto protector contra la sequía en plantas de maní
(Centro de Ingenieros Agrónomos General Cabrera, 2022-09-15)La variabilidad y escasez de precipitaciones estacionales generan perdidas de hasta el 30% de la cosecha de maní. Existen bacterias benéficas capaces de proteger a las plantas de los daños por sequia Esos mecanismos ... -
