Fungal Communities Associated with Peacock and Cercospora Leaf Spots in Olive.

ABSTRACT: Venturia oleaginea and Pseudocercospora cladosporioides are two of the most important olive fungal pathogens causing leaf spots: peacock spot, and cercosporiosis, respectively. In the present study, fungal communities associated with the presence of these pathogens were investigated. Overall, 300 symptomatic and asymptomatic trees from different cultivars were sampled from Alentejo, Portugal. A total of 788 fungal isolates were obtained and classified into 21 OTUs; Ascomycota was clearly the predominant phylum (96.6%). Trees from cultivar 'Galega vulgar' showed a significant higher fungal richness when compared to 'Cobrançosa', which in turn showed significant higher values than 'Picual'. Concerning plant health status, symptomatic plants showed significant higher fungal richness, mainly d
