A DNA barcode for land plants
The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.
Unraveling the evolutionary history of the liverworts (Marchantiophyta): multiple taxa, genomes and analyses
Nucleotide sequence data from three chloroplast genes, one nuclear gene and one mitochondrial gene were assembled for 173 species in 117 genera of liverworts, making this the largest molecular phylogeny of the group to date, providing support for the monophyly of the liverwort and for previously resolved backbone relationships within the Marchantiophyta.
Selecting barcoding loci for plants: evaluation of seven candidate loci with species‐level sampling in three divergent groups of land plants
Evaluated the seven main candidate plastid regions in three divergent groups of land plants, no single locus showed high levels of universality and resolvability and when multiple loci were combined, fewer barcodes were shared among species.
Pleistocene and pre-Pleistocene Begonia speciation in Africa.
Divergence times and the evolution of morphological complexity in an early land plant lineage (Marchantiopsida) with a slow molecular rate.
A complete generic-level phylogeny of the complex thalloid liverworts, a lineage that includes the model system Marchantia polymorpha, provides a temporal framework for the analysis of the evolution of critical traits essential for plants during land colonization.
Phylogenetic position and biogeography of Hillebrandia sandwicensis (Begoniaceae): a rare Hawaiian relict.
Preliminary analyses indicate that the Hillebrandia lineage is at least 51-65 million years old, an age that predates the current Hawaiian Islands by about 20 million years, and suggests a boreotropic or a Malesian-Pacific origin is most likely.
High Rates of Gene Flow by Pollen and Seed in Oak Populations across Europe
The high levels of gene flow in eight stands of white oak suggest that geographically remote oak stands are unlikely to be genetically isolated, questioning the static definition of gene reserves and seed stands.
Evolutionary trends in the simple thalloid liverworts (Marchantiophyta, Jungermanniopsida subclass Metzgeriidae)
Reconstructions of morphological character evolution on the combined analysis topology confirm that there is substantial homoplasy in the morphology dataset, even in characters that have been traditionally considered diagnostic of hierarchial relationships, such as apical cell geometry, calyptral type and capsule wall thickness.
Dating the diversification of pleurocarpous mosses
The hypothesis that pleurocarpous mosses evolved toexploit the angiosperm forests is modified — pleurodynamic mosses diversified in the same time frame as the early angiosperms and the recovered pattern suggests a putative correlation of thesediversification events.
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.
