Abstract


In an investigation of rust fungi in Qinghai Province, northwestern China, the novel rust species Gymnosporangium przewalskii was identified based on morphology and phylogenetic analyses. Phylogenetic analyses using the internal transcribed spacers (ITS) and the large subunit (LSU) rRNA partial gene revealed that G. przewalskii is monophyletic and distinct from other Gymnosporangium species. The life cycle of this new taxon was clarified based on molecular data. Its spermogonial and aecial stages occurred on Sorbus koehneana, and its telial stage was found on Juniperus przewalskii.
