We report the chloroplast genomes of a tree fern (Dicksonia squarrosa) and a “fern ally” (Tmesipteris elongata), and show that the phylogeny of early land plants is basically as expected, and the estimates of divergence time are largely unaffected after removing the fastest evolving sites. The tree fern shows the major reduction in the rate of evolution, and there has been a major slowdown in the rate of mutation in both families of tree ferns. We suggest that this is related to a generation…

The flying spider-monkey tree fern genome provides insights into fern evolution and arborescence
TLDR
The genome of Alsophila spinulosa, known as the flying spider-monkey tree fern, is assembled onto 69 pseudochromosomes and a phenolic compound, alsophilin, that is abundant in xylem is identified, and the molecular basis for its biosynthesis is provided.
A transcriptome for the early-branching fern Botrychium lunaria enables fine-grained resolution of population structure
TLDR
A transcriptome is established for Botrychium lunaria, a diploid species with an extremely large genome and it is shown that the new transcriptome improves phylogenetic resolution among early-branching ferns, and identifies unexpected variation in population-level heterozygosity.
Advances in the evolution of plastid genome structure in lycophytes and ferns
TLDR
The current understanding of lycophyte and fern plastid genome structure and its variation is summarized, which includes large inversions, boundary shifts of repeat regions, gene and intron loss, and some of which could be recognized as synapomorphies of higher taxonomic ranks.
Systematics and Plastome Evolution in Schizaeaceae
TLDR
The loss of all plastid NADH-like dehydrogenase genes was confirmed to have occurred in the ancestor of extant Schizaeaceae, which coincides with the evolution of mycoheterotrophy in this family, and the current PPG I circumscription of Schizaea is non-monophyletic.
A phylogenomic approach reveals a low somatic mutation rate in a long-lived plant
TLDR
A novel method to measure somatic mutations in individual plants is demonstrated and this approach is used to estimate the somatic mutation rate in a large, long-lived, phenotypically mosaic Eucalyptus melliodora tree.
Structural Variation of Plastomes Provides Key Insight Into the Deep Phylogeny of Ferns
TLDR
The inversion V5 and V7 together filled the crucial gap regarding how the “reversed” gene orientation in the IR region characterized by most extant ferns evolved from the inferred ancestral type as retained in Equisetales and Osmundales, thus providing key insight into the paraphyly of Gleicheniales.
Plastid Phylogenomics Resolve Deep Relationships among Eupolypod II Ferns with Rapid Radiation and Rate Heterogeneity
TLDR
This study demonstrates the power of a character-rich plastome data set and high-throughput sequencing for resolving the recalcitrant lineages, which have undergone rapid evolutionary radiation and dramatic changes in substitution rates.

Horsetails and ferns are a monophyletic group and the closest living relatives to seed plants
TLDR
It is shown that there are three monophyletic groups of extant vascular plants: (1) lycophytes, (2) seed plants and (3) a clade including equisetophytes (horsetails, psilotophytes) and all eusporangiate and leptosporangiates ferns.
Overcoming deep roots, fast rates, and short internodes to resolve the ancient rapid radiation of eupolypod II ferns.
TLDR
Among the significant phylogenetic results is the near-complete support along the eupolypod II backbone, the demonstrated paraphyly of Woodsiaceae as currently circumscribed, and the well-supported placement of the enigmatic genera Homalosorus, Diplaziopsis, and Woodsia.
The evolutionary root of flowering plants.
TLDR
It is shown that support for Amborella as the sole representative of the most basal angiosperm lineage is founded on sequence site patterns poorly described by time-reversible substitution models, and indicates that aquatic and herbaceous species dominate the earliest extant lineage of flowering plants.
Utility of a large, multigene plastid data set in inferring higher-order relationships in ferns and relatives (monilophytes).
TLDR
The utility of this plastid-based data set in corroborating relationships found in previous studies, improving support, and resolving uncertainties in monilophyte phylogeny is supported.
Systematic Error in Seed Plant Phylogenomics
TLDR
It is shown that non-time reversible properties of aligned sequence positions in the chloroplast genomes of Gnetales mislead phylogenetic reconstruction of these seed plants, highlighting the importance of goodness of fit between substitution model and data for understanding seed plant phylogeny.
Rates of Molecular Evolution Are Linked to Life History in Flowering Plants
TLDR
Exceptionally large phylogenies of five major angiosperm clades demonstrate that rates of molecular evolution are consistently low in trees and shrubs, with relatively long generation times, as compared with related herbaceous plants, which generally have shorter generation times.
Separating the wheat from the chaff: mitigating the effects of noise in a plastome phylogenomic data set from Pinus L. (Pinaceae)
TLDR
It is suggested that removal of misleading signal in phylogenomic datasets can result not only in increased resolution for poorly supported nodes, but may serve as a tool for identifying erroneous yet highly supported topologies.
A Nonflowering Land Plant Phylogeny Inferred from Nucleotide Sequences of Seven Chloroplast, Mitochondrial, and Nuclear Genes
TLDR
Most of the relationships among all major lineages of nonflowering land plants are supported by bootstrap values of 75% or higher, except those among basal monilophyte lineages and among some gymnosperm lineages, probably because of extinctions.
Origin of land plants using the multispecies coalescent model.
Rate heterogeneity among lineages of tracheophytes: Integration of molecular and fossil data and evidence for molecular living fossils
TLDR
This study minimize the potential error caused by inaccurate topology and uncertain calibration times by using a well-supported tree, multiple genes, and multiple well-substantiated dates to explore the correspondence between the fossil record and molecular-based age estimates for major clades of tracheophytes.
