Phylotranscriptomic analysis of the origin and early diversification of land plants
Strong and robust support is found for a sister-group relationship between land plants and one group of streptophyte green algae, the Zygnematophyceae, and suggests that phylogenetic hypotheses used to understand the evolution of fundamental plant traits should be reevaluated. Expand
Data access for the 1,000 Plants (1KP) project
How to access the data used in a phylogenomics analysis of the first 85 species, and how to visualize the gene and species trees of the 1KP project. Expand
Progress and challenges toward developing a phylogeny and classification of the hornworts
Molecular phylogenetic analyses of hornworts were performed on a nucleotide data set consisting of mitochondrial nad5, chloroplast rbcL and nuclear 18S gene regions, confirming the relationships observed but also revealing a number of previously unrecognized yet highly supported clades. Expand
A review of molecular-clock calibrations and substitution rates in liverworts, mosses, and hornworts, and a timeframe for a taxonomically cleaned-up genus Nothoceros.
This work formally transfer two species of Megaceros into Nothoceros, resulting in the new combinations N.C. Villarreal and N. schizophyllus, and newly synonymize eight names described inMegaceros. Expand
Bryophyte Biology: New insights into morphology, anatomy, and systematics of hornworts
Virtually every aspect of hornwort evolution has been challenged and/or revised since the publication of the first edition of this book and Phylogenetic hypotheses based on multigene sequences have revolutionized the authors' concepts of interrelationships. Expand
A synthesis of hornwort diversity: Patterns, causes and future work
Estimates of hornwort species richness worldwide, identifying centers of diversity and two examples of the impact of recent work in elucidating the composition and circumscription of the genera Megaceros and Nothoceros are presented. Expand

It is found that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns. Expand
World checklist of hornworts and liverworts
The first-ever worldwide checklist for liverworts and hornworts is presented that includes 7486 species in 398 genera representing 92 families from the two phyla, providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps. Expand
Phytochrome diversity in green plants and the origin of canonical plant phytochromes
It is shown that canonical plant phytochromes originated in a common ancestor of streptophytes (charophyte algae and land plants) and Surprisingly, the phy tochrome portions of algal and land plant neochromes, a chimera ofphytochrome and phototropin, appear to share a common origin. Expand
Extant diversity of bryophytes emerged from successive post-Mesozoic diversification bursts.
Overall estimates of net species diversification are approximately half those reported in ferns and ∼30% those described for angiosperms, and statistical rate analyses reveal that mosses and liverworts underwent bursts of diversification since the mid-Mesozoic. Expand
