| dc.description.abstract | Xylella fastIdiosa is a bacterium transmitted by insectvectors that cause high losses in a variety ofagriculturally important crops. In Europe, an outbreak ofthe disease was recently detected in olive trees, being Philaenus spumarius só far identífied as the only vector involved in this outbreak. Thus, vector contrai by using bait plants and/or insect repellents that emit volatile compounds produced by microorganisms that colonize host plants [endophyte] may help to reduce the dissemination ofthe disease. In this work the endophytic fungal community of Coleostephus myconis, a ground cover plant present in the olive graves and commonly infested by P. spumarius, was studied. Fungi were isolated from stems, leaves and inflorescences ofplants with three leveis of P. spumarius infestation, collected in an olive grove located in Mirandela. The fungal isolates obtained were identified by sequencing the ITS region of rDNA the partial tefl. A total of 121 species/genera were identified, bemg Alternaria, Chalastospora and Valsa the most abundant genera. The diversity and abundance of endophytic fungi was higher in the leaf and inflorescences than in the stem. The composition and diversity of endophytic fungal community was different between infested and non-infested plants, especially at the levei of their leaves. Endophyte community similarity between the different plant organs was low, especially between stem and inflorescences. Altogether, the results show that P. spumaríus affects the composition and structure ofendophytic fungal community associated to C. myconis, especially in their leaves. The effect of this change in the fungal community in attractiveness/ repulsion of P. spumarius should be studied in the future. | pt_PT |
