COSTA, Daniela; TAVARES, Rui M.; BAPTISTA, Paula  y  LINO-NETO, Teresa. Diversity of fungal endophytic community in Quercus suber L. under different climate scenarios. Rev. de Ciências Agrárias [online]. 2018, vol.41, n.spe, pp.41-50. ISSN 0871-018X.  https://doi.org/10.19084/RCA.17063.

Cork oak (Quercus suber L.) is an evergreen oak tree species, typically found throughout the Mediterranean Basin, which presents a great ecological and economic importance for Portugal. An increase of cork oak decline due to biotic and abiotic stresses has been reported, which could damage the ecosystem and lower cork production. The attack of some fungal pathogens seems to increase when trees are under several environmental stresses, such as increased temperatures or drought. In this work, fungal endophytic species of cork oak were collected from forest stands in different sites of Portugal. The community of fungal endophytes of young and old twigs was studied by obtaining fungal isolates from plant material and grouping them into morphotypes. This study allowed the comparison of fungal endophytic communities living in cork oak trees from different forests, displaying distinct climates and water availability levels. The results revealed that endophyte communities are better discriminated when considering different plant tissues than cork oak stand location or climate.

Palabras clave : cork oak; endophyte; endophytic community; fungi.
