“…Remarkably, the homoplasy we observed may even span across subclasses. Sorapilla , the sole member of Sorapillaceae, was originally placed in the Dicranidae, but was then moved to the Hypnales, where it currently resides with unknown affinities (Meagher et al, 2020). Based on the first DNA sequences obtained for this genus, we resolve the Sorapillaceae in the Dicranidae as proposed earlier (Lin, 1983; Vitt, 1984) but in an isolated position within the Dicranalean grade (Figure 2; Appendices S4, S7), prompting us to propose a new order, Sorapillales, for it (see taxonomic treatment below).…”

PremiseBryophytes form a major component of terrestrial plant biomass, structuring ecological communities in all biomes. Our understanding of the evolutionary history of hornworts, liverworts and mosses has been significantly reshaped by inferences from molecular data, which have highlighted extensive homoplasy in various traits and repeated bursts of diversification. However, the timing of key events in the phylogeny, patterns and processes of diversification across bryophytes remain unclear.MethodsUsing the GoFlag probe set we sequenced 405 exons representing 228 nuclear genes for 531 species from 52 of the 54 orders of bryophytes. We inferred the species phylogeny from gene tree analyses using concatenated and coalescence approaches, assessed gene conflict, and estimated the timing of divergences based on 29 fossil calibrations.ResultsThe phylogeny resolves many relationships across the bryophytes, enabling us to resurrect five liverwort orders and recognize three more, and propose ten new orders of mosses. Most orders originated in the Jurassic and diversified in the Cretaceous or later. The phylogenomic data also highlight topological conflict in parts of the tree, suggesting complex processes of diversification that cannot be adequately captured in a single gene‐tree topology.ConclusionsWe sampled hundreds of loci across a broad phylogenetic spectrum spanning at least 450 Ma of evolution; these data resolved many of the critical nodes of the diversification of bryophytes. The data also highlight the need to explore the mechanisms underlying the phylogenetic ambiguity at specific nodes. The phylogenomic data provide an expandable framework toward reconstructing a comprehensive phylogeny of this important group of plants.This article is protected by copyright. All rights reserved.
