Divergent evolutionary trajectories of bryophytes and tracheophytes from a complex common ancestor of land plants

It is confirmed that extant tracheophytes and bryophytes are both highly derived; as a result, understanding the origin of land plants requires tracing character evolution across the diversity of modern lineages.

Deep origin and gradual evolution of transporting tissues: Perspectives from across the land plants

Improved knowledge of the intimate structure and developmental regulation of transporting tissue across the entire taxonomic breadth of extant plant lineages is required for a full understanding of the evolutionary trajectory of transporting tissues.

An open and continuously updated fern tree of life

This work develops a mostly automated, reproducible, open pipeline to generate a continuously updated fern tree of life (FTOL) from DNA sequence data available in GenBank, and uses a curated reference taxonomy to resolve synonyms in general compliance with the community-driven Pteridophyte Phylogeny Group I classification.

How was apical growth regulated in the ancestral land plant? Insights from the development of non-seed plants

Developmental genetic studies of apical regulators and speculate on their likely evolutionary history are reviewed.

Composition of continental crust altered by the emergence of land plants

The evolution of land plants during the Palaeozoic era transformed Earth’s biosphere. Because the Earth’s surface and interior are linked by tectonic processes, the linked evolution of the biosphere

Cultivation of widespread Bathyarchaeia reveals a novel methyltransferase system utilizing lignin-derived aromatics

Culturing of Candidatus Marisediminiarchaeum ligniniphilus DL1YTT001, a Bathyarchaeial representative from nearshore marine sediments that can grow with lign in as the sole organic carbon source under mesophilic and anaerobic conditions, shows O-demethylation activity with guaiacol as the substrate.

Evolution and function of red pigmentation in land plants

The evidence suggests that pigment biosynthetic pathways have evolved numerous times in land plants to provide compounds that have red colour to screen damaging photosynthetically active radiation but that also have secondary functions that provide specific benefits to the particular land plant lineage.

Evolution of meristem zonation by CLE gene duplication in land plants.

A model for the evolution of meristem zonation is proposed that suggests that a stem-cell-limiting CLV3 pathway is derived from stem- cell-promoting CLE pathways conserved in land pants by gene duplication in the angiosperm lineage.

Evolutionary Analysis and Functional Identification of Ancient Brassinosteroid Receptors in Ceratopteris richardii

It is found that BR promotes the growth of Ceratopteris richardii, while the synthetic inhibitor PCZ inhibits the growth, and the kinase domains of these four receptors could trigger BR downstream signaling.

Unveiling the nature of a miniature world: a horizon scan of fundamental questions in bryology

ABSTRACT Introduction Half a century since the creation of the International Association of Bryologists, we carried out a review to identify outstanding challenges and future perspectives in



Major transitions in the evolution of early land plants: a bryological perspective.

This paper reviews phylogenetic, developmental, anatomical, genetic and paleontological data with the aim of reconstructing the succession of events that shaped major land plant lineages and concludes that bryophytes are the key to a better understanding of the early evolution of land plants.

Land Plant Molecular Phylogenetics: A Review with Comments on Evaluating Incongruence Among Phylogenies

The molecular phylogenetic evidence for relationships is reviewed and evaluated and it is concluded that the two better-supported hypotheses are, firstly, that the bryophytes are a monophyletic group, and secondly, and less likely, that a lineage consisting of liverworts and mosses branched first among land plants with the hornworts the most-closely related lineage to tracheophytes.

The Chloroplast Land Plant Phylogeny: Analyses Employing Better-Fitting Tree- and Site-Heterogeneous Composition Models

Analyses of non-synonymous site nucleotide data and amino acid translation data result in congruent phylogenetic trees showing the monophyly of bryophytes, with the Zygnematophyceae as the charophyte group most closely related to land plants.

Conflicting Phylogenies for Early Land Plants are Caused by Composition Biases among Synonymous Substitutions

Despite the similarity among land–plant life cycles, they differ in one significant aspect: in the three bryophyte groups, the haploid gametophytic stage is the dominant vegetative stage, whereas in vascular plants the diploid sporophyte dominates.

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.
