Beneficial effects of Neotyphodium tembladerae and Neotyphodium pampeanum on a wild forage grass
Iannone, Leopoldo Javier; Pinget, Albertina Daniela; Nagabhyru, P.; Schardl, Christopher L.; De Battista, Jose Pedro (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
Vignale, Maria Victoria; Iannone, Leopoldo Javier; Pinget, Albertina Daniela; De Battista, Jose Pedro; Novas, María Victoria (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
Iannone, Leopoldo Javier; Novas, María Victoria; Young, Carolyn A.; De Battista, Jose Pedro; Schardl, Christopher L. (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 ... -

Zabaleta, Gabriela; Lee, Stephen T.; Cook, Daniel; Aguilar, Marcelo Javier; Iannone, Leopoldo Javier; Robles, Carlos Alejandro; Martinez, Agustin (Elsevier, 2022-10-15)One of the main intoxications to livestock in the Patagonia region of Argentina is the tremorgenic disease “Mal de Huecú", attributed to the consumption of the native grasses Poa huecu and/or Festuca argentina. In this ... -
Seed-transmitted Epichloë sp. endophyte alleviates the negative effects of head smut of grasses (Ustilago bullata) on Bromus auleticus
Iannone, Leopoldo Javier; Vignale, Maria Victoria; Pinget, Albertina Daniela; Re, Alejo Esteban; Mc Cargo, Patricia Débora; Novas, María Victoria (2017)Some grasses are co-infected by ‘castrator’ fungal pathogens, such as Ustilago bullata, and beneficial seed transmitted Epichlo€e endophytes that compete for plant photosynthates and flowers. Epichlo€e-infected (E+) and ...
