Resumen
[ES] Los hongos patógenos y descomponedores desempeñan roles esenciales en los ecosistemas, y sus interacciones con las plantas huésped pueden estar influenciadas por la filogenia y el fenotipo de las especies. Mediante conjuntos de datos tomados in situ y datos previamente publicados se evaluó la
composición fúngica de la filosfera y la rizosfera de 4 especies de plantas leñosas ubicadas en la Sierra Sur
de Jaén. Se testó el efecto de la filogenia y los rasgos funcionales de las plantas en las comunidades fúngicas. Los resultados mostraron que la proximidad filogenética entre especies vegetales favorece la compartición de patógenos foliares, mientras que especies con sistemas radiculares similares albergan comunidades de hongos patógenos más parecidas en la rizosfera. Se concluye que la especificidad en las interacciones planta-hongo está modulada por factores filogenéticos y fenotípicos de las plantas.
[EN] Pathogenic and decomposer fungi play essential roles in ecosystems, and their interactions with host plants may be influenced by species phylogeny and phenotype. Using data sets collected in situ and previously published data, the fungal composition of the phyllosphere and rhizosphere of 4 woody plant species located in the Sierra Sur de Jaén was evaluated. The effect of phylogeny and plant functional traits on fungal communities was tested. The results showed that phylogenetic proximity between plant species favours the sharing of foliar pathogens, while species with similar root systems are home to more similar pathogenic fungal communities in the rhizosphere. It is concluded that specificity in plant-fungus interactions is modulated by plant phylogenetic and phenotypic factors.
