Dothideomycetes is one of the largest and most diverse classes within the largest fungal phylum, Ascomycota. It contains a diverse group of fungi that subsist as general saprobes, plant and human pathogens, fungal parasites, mycorrhizae, lichens, and aquatic and marine fungi. Few other eukaryotic groups share this enormous ecological diversity. The best-known members of the group are plant pathogens that cause serious crop losses, but the majority of Dothideomycetes phylogenetic relationships are poorly known. A well-resolved evolutionary history is especially important because it provides the framework for understanding how fungi change in adapting to new environments and nutritional modes. A dynamic evolutionary history is reflected in the ecology of the Dothideomycetes. The ecological diversity of the class may hint at an unrevealed similarity in all fungi or it may reveal the unique ways that each of these groups adapt to the environment. As such, the Dothideomycetes provide an excellent system to gain insight into environmental adaptation. By using a broad approach to sampling in the group, this study aims to address ancient relationships while simultaneously expanding the knowledge of species diversity in the class. The project will rely on international collaboration and will link data generated about genetics, plant pathology, systematics, and taxonomy. Results will be communicated by workshops, publications, and the internet.

Dothidemycetes是最大，最大的真菌门，Ascomycota中最大，最多样化的类别之一。它包含一种多样化的真菌，它们作为一般腐生，植物和人类病原体，真菌寄生虫，菌根，地衣以及水生和海洋真菌。很少有其他真核生物群具有这种巨大的生态多样性。该组中最著名的成员是造成严重农作物损失的植物病原体，但是大多数多甲基菌的系统发育关系是鲜为人知的。分辨出良好的进化历史尤其重要，因为它为了解真菌如何适应新环境和营养模式提供了一个框架。动态进化史体现在dothidemosycetes的生态学中。班级的生态多样性可能暗示着所有真菌中未透露的相似性，或者它可能揭示了这些群体适应环境的独特方式。因此，dothidemosycetes提供了一个很好的系统，可以深入了解环境适应。通过在小组中使用广泛的采样方法，本研究旨在解决古老的关系，同时扩大班级物种多样性的知识。该项目将依靠国际协作，并将生成有关遗传学，植物病理学，系统学和分类法的数据链接。结果将由研讨会，出版物和互联网传达。
