Genetic Diversity of Colletotrichum spp. an Endophytic Fungi in a Medicinal Plant, Brazilian Pepper Tree.

ABSTRACT: In this study, we reported thirty-nine endophytic fungi identified as Colletotrichum spp. associated with Brazilian pepper tree or aroeira (Schinus terebinthifolius Raddi. Anacardiaceae) in Paraná state, Brazil. These endophytes were identified by morphological and molecular methods, using PCR taxon-specific with CaInt/ITS4, CgInt/ITS4, and Col1/ITS4 primers, which amplify specific bands in C. acutatum, C. gloeosporioides lato sensu, and Colletotrichum boninensis, respectively, and by DNA sequence analysis of the nrDNA internal transcribed spacer region (ITS1, 5.8S, ITS2). We also assayed the presence of dsRNA particles in Colletotrichum spp. isolates. Combining both morphological characters and molecular data, we identified the species C. gloeosporioides, C. boninense, and C. simmondsii.
