| Zusammenfassung: | © 2021 The Authors. Journal of Phycology published by Wiley Periodicals LLC on behalf of Phycological Society of America. Here, we present new transcriptome sequencing data from seven species of Dasycladales (Ulvophyceae) and a phylogenomic analysis of the Chlorophyta with a particular focus on Ulvophyceae. We have focused on a broad selection of green algal groups and carefully selected genes suitable for reconstructing deep eukaryote evolutionary histories. Increasing the taxon sampling of Dasycladales restructures the Ulvophyceae by identifying Dasycladales as closely related to Scotinosphaerales and Oltmannsiellopsidales. Contrary to previous studies, we do not find support for a close relationship between Dasycladales and a group with Cladophorales and Trentepohliales. Instead, the latter group is sister to the remainder of the Ulvophyceae. Furthermore, our analyses show high and consistent statistical support for a sister relationship between Bryopsidales and Chlorophyceae in trees generated with both homogeneous and heterogeneous (heterotachy) evolutionary models. Our study provides a new framework for interpreting the evolutionary history of Ulvophyceae and the evolution of cellular morphologies |
