“…Various branching orders have been recovered in previous studies, generally with poor support (e.g. Goffinet et al., ; Bell et al., ; O'Brien, ; Cox et al., ). Rhizogoniales and the core pleurocarps have been referred to collectively as “pleurocarpids” (Bell et al., ), but the monophyly of Rhizogoniales (and also pleurocarpids) is doubtful according to our parsimony and likelihood analyses, as Rhizogonium (Rhizogoniales) is weakly supported as the sister group of Orthotrichium (Orthotrichales) (clade gg in Fig.…”

Relationships among the major branches of moss phylogeny are understudied compared with other major land-plant groups. We addressed this by surveying 14-17 plastid genes from taxa representing the major lineages, using different phylogenetic methods (parsimony, likelihood) and codon-and gene-based data partitioning schemes (likelihood). Our phylogenetic inferences generally corroborated the best supported clades across multiple recent studies, with comparable or higher levels of clade support here. We resolved persistent ambiguities with strong to moderate support across analyses, including several early nodes in subclass Dicranidae, and relationships among other subclasses of peristomate mosses. In particular, we resolved a sister-group relationship between Bryidae and Dicranidae, between these subclasses and Timiidae, and between this entire clade and Funariidae. We consistently recovered Tetraphidopsida (a nematodontous class) as the sister group of arthrodontous mosses (Bryopsida), although with only weak support. Strongly conflicting arrangements at the base of moss phylogeny concerning Takakiopsida and Sphagnopsida, two non-peristomate moss lineages, were inferred in parsimony and likelihood analysis, but this depended on how base-frequency parameters were estimated and how data were partitioned in likelihood analysis. Relationships inferred for the remaining peristomate and non-peristomate moss clades, and their associated support values, were otherwise broadly congruent across analyses.

“…Due to its conserved nature, rbcL has only been employed at the family level and above in recent publications (e.g. Shaw et al 2003;Forrest et al 2006;Bell et al 2007;Heinrichs et al 2005;2007;Wahrmund et al 2010) and is not suitable for species and population level analysis or barcoding approaches in bryophytes. This contrasts with Newmaster et al (2006) and Liu et al (2010), who considered rbcL as the marker with the best performance as DNA barcode in bryophytes.…”

A number of reviews have accompanied and monitored the progress of molecular phylogenetic research on bryophytes, focusing on the publication record itself, bryophyte phylogeny and systematics in the molecular era, as well as the evolution and phylogenetic utility of markers from different genomes. However, none of the recent reviews include a detailed characterization of all molecular markers used in bryophyte phylogenetics. Here we provide an overview of the history and current state of marker utilization, including coding and non-coding sequence markers from all three genomes as well as fingerprinting approaches. The molecular architecture and evolutionary peculiarities, as well as practical aspects such as amplification and sequencing strategies, are outlined for the DNA sequence markers, with a focus on the most commonly employed regions. Their phylogenetic utility and potential for solving some of the remaining, pressing questions in bryophyte phylogeny, as well as their suitability for molecular species identification by DNA barcoding, are discussed.

This study involves bryophyte fossils from the Teresina Formation (Permian-Guadalupian) collected in the Rio Preto Quarry in the state of Paraná, southern Brazil. Two new genera are proposed, with two new species: Capimirinus riopretensis sp. nov. and Yguajemanus yucapirus sp. nov. C. riopretensis sp. nov. included a lateral sporophyte that was organically attached to a gametophyte and is thus one of the oldest pleurocarpous fossils known today. This discovery provides clear evidence of the evolution of mosses during the Permian, because an acrocarpous moss from this period was also found in India. The preservation of such a fragile structure demonstrates that no prefossilization displacement took place and that the sediments accumulated in a low-energy, fresh-water environment, similar to a lake fed by rain, and isolated from the direct influence of the sea. Campimirinus riopretensis may be placed within the earlier pleurocarps, and Yguajemanus yucapirus sp. nov. may belong to the Bryalean families. However, we were not able to place neither of these species in any existing family today.
