Abstract

A phylogenetic redefinition of anamorph genera in Mycosphaerella based on ITS rDNA sequence and morphology Pedro W. Crous1, Ji-Chuan Kang1 and Uwe Braun2 1Department of Plant Pathology, University of Stellenbosch, P. Bag X1, Matieland 7602, South Africa 2Martin-Luther-Universitt, FB. Biologie, Institut f?r Geobotanik und Botanischer Garten, Neuwerk 21, D-06099 Halle (Saale), Germany Mycologia (accepted) Abstract: Anamorph genera associated with Mycosphaerella are separated on a combination of characters such as conidiomatal structure, the nature and arrangement of conidiophores and dehiscence scars and pigmentation. To date 27 genera have been reported as anamorphs of Mycosphaerella, 18 of which were included in this study. Based on the phylogeny of the ITS1, 5.8S and ITS2 rDNA sequence data, Mycosphaerella proved to be largely monophyletic. The major group consisted of several small clusters correlating to specific anamorph genera, as well as other clusterss containing an assemblage of anamorph genera. Although Mycosphaerella is monophyletic, it appears that the morphological characters defining different anamorph genera evolved more than once and for the most do not represent true groups within Mycosphaerella. Nevertheless, the anamorph generic concepts contain valuable information of practical use to plant pathologists and mycologists working with these organisms. Based on these results, as well as a re-evaluation of the criteria upon which anamorph genera are distinguished in this complex, a reduced set of informative criteria and genera are proposed.
