... The Charales, the Coleochaetales or more recently the Zygnematales have been considered to be the sister group ... embryophytes. Our phylogenetic analyses indicate that either the Zygnematales or a clade consisting of the Zygnematales and the Coleochaetales are the sister group to ... the closest living relatives of embryophytes. Instead, the Zygnematales or a clade consisting of Zygnematales and Coleochaetales are most likely the sister group ... data are needed to confirm this conclusion. A Zygnematales/embryophyte sister group relationship has important implications for ...
