Cymadothea trifolii, an obligate biotrophic leaf parasite of Trifolium, belongs to Mycosphaerellaceae as shown by nuclear ribosomal DNA analyses
Persoonia 22, 49-55
Abstract: The ascomycete Cymadothea trifolii, a member of the Dothideomycetes, is unique among obligate biotrophic fungi in its capability to only partially degrade the host cell wall and in forming an astonishingly intricate interaction apparatus (IA) in its own hyphae, while the attacked host plant cell is triggered to produce a membranous bubble opposite the IA. However, no sequence data are currently available for this species. Based on molecular phylogenetic results obtained from complete SSU and partial LSU data, we show that the genus Cymadothea belongs to the Mycosphaerellaceae (Capnodiales, Dothideomycetes). This is the first report of sequences obtained for an obligate biotrophic member of Mycosphaerellaceae.
