Abstract

Previous studies regarding endophytic fungi associated with Cinchona were focused on the analysis of quinine and related fungal metabolites. In the current study, the community structure of culturable endophytic fungi associated with C. calisaya (i.e., leaf, petiole, twig, root, flower, and fruit) were analyzed and elucidated. Representative isolates from various morphotypes were identified based on a sequence generated from the Internal Transcribed Spacer (ITS) rDNA region. A total of 638 fungal strains were isolated from 700 plant segments. All isolates belong to the phylum Ascomycota and are dominated by a member of Sordariomycetes. The fungal endophyte community within C. cali-saya consists of 23 known species, 10 species complexes, and 6 unidentified species. Based on the Shannon-Wiener diversity index, the leaves and fruits host the most diverse endophytic fungi, followed by twigs, petioles, and bark. Members of the genus Diaporthe are commonly found in all C. calisaya organs. Neofussicoccum sp. was only one found within twigs; the Colletotrichum gloeosporioides complex and Guignardia mangiferae were only found within leaves; the C. brasiliense complex was detected in flowers; and Fusarium oxysporum is specific to roots.

Abstract

Identification of the genus Cercospora is still complicated due to the host preferences often being used as the main criteria to propose a new name. We determined the relationship between host plants and multilocus sequence variations (ITS rDNA including 5.8S rDNA, elongation factor 1-α, and calmodulin) in Cercospora spp. to investigate the host specificity. We used 53 strains of Cercospora spp. infecting 12 plant families for phylogenetic analysis. The sequences of 23 strains of Cercospora spp. infecting the plant families of Asteraceae, Cucurbitaceae, and Solanaceae were determined in this study. The sequences of 30 strains of Cercospora spp. infecting the plant families of Fabaceae, Amaranthaceae, Apiaceae, Plumbaginaceae, Malvaceae, Cistaceae, Plantaginaceae, Lamiaceae, and Poaceae were obtained from GenBank. The molecular phylogenetic analysis revealed that the majority of Cercospora species lack host specificity, and only C. zinniicola, C. zeina, C. zeae-maydis, C. cocciniae, and C. mikaniicola were found to be host-specific. Closely related species of Cercospora could not be distinguished using molecular analyses of ITS, EF, and CAL gene regions. The topology of the phylogenetic tree based on the CAL gene showed a better topology and Cercospora species separation than the trees developed based on the ITS rDNA region or the EF gene.
