Studies comparing fungal endophytes between above- and belowground woody crop organs and the
factors that may structure their communities are lacking. Due to its great impact on the Mediterranean
Basin, the olive tree was chosen for the isolation of endophytic fungi from roots, leaves and twigs in two
seasons in north-eastern Portugal. Nine hundred seventy-six isolates belonging to 38 fungal species were
obtained. Phomopsis columnaris, Fusarium oxysporum and Trichoderma gamsii were the most frequently
isolated, collectively representing 69% of the isolates. Fungal diversity in the roots was higher than in the
aboveground organs and higher in spring than autumn. Endophyte community similarity between the
above- and belowground organs and between seasons was low. Species composition also varied spatially,
with the fungal composition of the roots varying more among locations than that of the aboveground
organs. Our results suggest olive tree endophyte community structure is affected by plant organ, location
and season.
