Abstract | The occurrence of pathogenic and endophytic species of Phyllosticta on cultivated Citrus in Australia was investigated by DNA sequence analysis of specimens held in plant pathology herbaria and culture collections. Sequences of the internal transcribed spacer region (ITS1, 5.8S, ITS2), and partial translation elongation factor 1-alpha (TEF) gene of 41 Phyllosticta-like isolates from Citrus were compared to those sequences from the type specimens of Phyllosticta recorded from around the world. Phylogenetic analysis resolved all the sequences of Australian accessions into two major clades. One clade corresponded to P. citricarpa, which causes citrus black spot disease. The other clade contained P. capitalensis, which is a known endophyte of Citrus and many other plant species. All included herbarium accessions previously designated as Guignardia mangiferae are now designated P. capitalensis. No Australian isolates were identified as the newly described pathogens of citrus P. citriasiana or P. citrichinaensis, or the endophytes Guignarida mangiferae, P. brazilianiae, or P. citribraziliensis. |
