Divergence times and the evolution of morphological complexity in an early land plant lineage (Marchantiopsida) with a slow molecular rate.
TLDR
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.
Retrieval of hundreds of nuclear loci from herbarium specimens
TLDR
It is shown that targeted enrichment through hybrid capture can be used to generate hundreds of kilobases of nuclear sequence data of the Neotropical genus Inga, from herbarium specimens as old as 180 years and using as little as 16 ng of degraded DNA.
The Limits of Hyb-Seq for Herbarium Specimens: Impact of Preservation Techniques
TLDR
A panel of specimens preserved using a variety of methods is used to assess whether Hyb-Seq is capable of retrieving informative amounts of sequence data from duplicate specimens preserved Using a range of specimen preservation methods, and the variation in error types between preservation techniques is presented.
On Monocarpus (Monocarpaceae, Marchantiopsida), an isolated salt-pan complex thalloid liverwort
Abstract. The phylogenetic placement of Monocarpus sphaerocarpus D.J.Carr (Monocarpaceae), a member of the complex thalloid liverworts with highly specialised morphology, presumably related to its
Molecular and morphological phylogenetics of the digitate-tubered clade within subtribe Orchidinae s.s. (Orchidaceae: Orchideae)
TLDR
Here, morphological phylogenetics with Sanger sequencing of nrITS and the plastid region trnL-F is integrated in order to explore phylogenetic relationships and phenotypic character evolution within the digitate-tubered clade of Orchidinae.
Preliminary insights from DNA barcoding into the diversity of mosses colonising modern building surfaces
TLDR
It is shown that samples with poor morphological characters due to incomplete development from modern building surfaces identified as “ Schistidium species” fall into several clades, and re-examination of the morphology of these samples shows some morphological differences, suggesting cryptic taxa.
Barcode UK: A complete DNA barcoding resource for the flowering plants and conifers of the United Kingdom
TLDR
Analyses of the genetic distinctiveness of species across a complete flora showed DNA barcoding to be informative for all but the most taxonomically complex groups, and the UK flora DNA barcode reference library provides an important resource for many applications that require plant identification from DNA.
Comparative phylogeography of five widespread tree species: Insights into the history of western Amazonia
TLDR
The lack of spatially congruent phylogeographic breaks across species suggests no common biogeographic history of these Amazonian tree species, which could be related to proposed Pleistocene refugia or the presence of geological arches in western Amazonia.
