Data from: Mutualism effectiveness and vertical transmission of symbiotic fungal endophytes in response to host genetic background

Pedro E. Gundel, María A. Martínez-Ghersa, Marina Omacini, Romina Cuyeu, Elba Pagano, Raúl Ríos & Claudio M. Ghersa
Certain species of the Pooideae subfamily develop stress tolerance and herbivory resistance through symbiosis with vertically-transmitted, asexual fungi. This symbiosis is specific, and genetic factors modulate compatibility between partners. Although gene flow is clearly a fitness trait in allogamous grasses, since it injects hybrid vigor and raw material for evolution, it could reduce compatibility and thus, mutualism effectiveness. To explore the importance of host genetic background in modulating the performance of symbiosis, Lolium multiflorum plants,...

Data from: Multigene phylogenetic analyses of the Thelonectria coronata and T. veuillotiana species complexes

Gary J. Samuels, Catalina Salgado-Salazar, Amy Y. Rossman, Mariana Capdet & Priscila Chaverri
Thelonectria is a recently established genus of common and ubiquitous fungi on woody hosts, previously placed in the genus Neonectria. Thelonectria coronata and T. veuillotiana occur sympatrically in several geographical areas in tropical, subtropical, and temperate regions. Previous taxonomic studies including T. coronata and T. veuillotiana suggested these fungi could represent species complexes; however, the morphological features used to define species exhibited few differences useful for testing this hypothesis. In order to assess the status...
