Phylogenetic relationships among the four major lineages of land plants (liverworts, mosses, hornworts, and vascular plants) remain vigorously contested; their resolution is essential to our understanding origin early evolution plants. We analyzed three different complementary data sets: a multigene supermatrix, genomic structural character matrix, chloroplast genome sequence using maximum likelihood, parsimony, compatibility methods. Analyses all sets strongly supported liverworts as sister...
A number of reviews have accompanied and monitored the progress molecular phylogenetic research on bryophytes, focusing publication record itself, bryophyte phylogeny systematics in era, as well evolution utility markers from different genomes. However, none recent include a detailed characterization all used phylogenetics. Here we provide an overview history current state marker utilization, including coding non-coding sequence three genomes fingerprinting approaches. The architecture...
We assessed soil fungal diversity at two sites on Deception Island, South Shetland Islands, Antarctica using DNA metabarcoding analysis. The first site was a relatively undisturbed area, and the second much more heavily impacted by research tourism. detected 346 amplicon sequence variants dominated phyla Ascomycota, Basidiomycota, Mortierellomycota Chytridiomycota. also taxa belonging to rare Mucoromycota Rozellomycota, which have been difficult detect in traditional isolation methods....
Bryophytes are a group of early land plants, whose specific ecophysiological and biological features, including poikilohydry, sensitivity to moderately high temperature dispersal ability, make them ideal candidates for investigating the impact climate changes. Employing combined approach species distribution modelling (SDM) molecular phylogeography in temperate moss Homalothecium sericeum, we explore significance Mediterranean refugia, contrasting southern northern refugia hypotheses,...
The Hypnales are the largest order of mosses comprising approximately 4200 species. Phylogenetic reconstruction within group has proven to be difficult due rapid radiation at an early stage evolution and, consequently, relationships among clades have remained poorly resolved. We compiled data from four sequence regions, namely, nuclear ITS1–5·8S–ITS2, plastid trnL–F and rps4, mitochondrial nad5, for 122 hypnalean species 34 closely related groups. Tree topologies both Bayesian parsimony...
Background Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with complex taxonomic history. Species circumscriptions and their relationships are subject to controversy; biogeographic history diversification through time unknown. Methodology Results We employed sequences of two chloroplast regions (trnL-trnF, rbcL) the nuclear ribosomal ITS region 332 accessions explore phylogeny Harpalejeunea-Lejeunea-Microlejeunea complex. forms well-supported clade that splits into main...
DNA sequences have been widely used for taxonomy, inferring phylogenetic relationships and identifying species boundaries. Several specific methods to define delimitations based on molecular phylogenies appeared recently, with the generalized mixed Yule coalescent (GMYC) method being most popular. However, only few studies land plants published so far GMYC analyses of bryophytes are missing. Dicranum is a large genus mosses whose (morpho-)species partly ill-defined frequently confused. To...
Introduction Half a century since the creation of International Association Bryologists, we carried out review to identify outstanding challenges and future perspectives in bryology. Specifically, have identified 50 fundamental questions that are critical advancing discipline.Methods We adapted deep-rooted methodology horizon scanning key research foci. An initial pool 258 was prepared by multidisciplinary international working group 32 bryologists. A series online surveys completed broader...

Abstract Phylogenetic analyses within the moss Homalothecium sericeum resolved two clades and four haplotypes in a polytomy. Because as one group exhibit comparable levels of genetic divergence to those observed among sister species genus, significant morphological differences, distinct geographic distributions, they are recognised three species. Discriminant analysis was employed assign types “forgotten” taxa previously recognized H. s.l. based on their morphology. While growing number...
The haplolepideous mosses (Dicranidae) form the second largest group of and are morphologically ecologically highly diverse. This review summarizes current state addresses most urgent remaining problems in unravelling systematic relationships mosses. main results early molecular phylogenetic reconstructions based on few chloroplast markers compared with recent approaches from different genomes as well a new phylogeny novel combination non-coding plastid (rps4-trnF region atpB-rbcL spacer)....
In bryophytes a morphological species concept is still most commonly employed, but delimitation of closely related based on characters often difficult. Here we test circumscriptions in complex the moss genus Racomitrium, R. canescens complex, variable DNA sequence markers from plastid (rps4-trnT-trnL region) and nuclear (nrITS) genomes. The extensive variability within has led to different opinions about number intraspecific taxa be distinguished. Molecular phylogenetic reconstructions...
From glacial reconstructions it is clear that Antarctic terrestrial life must have been extremely limited throughout Quaternary periods. In contrast, recent biological studies provide evidence for long-term in situ persistence times within most extant faunal and several microbial groups. However, even now, the evolutionary history of flora - despite playing major role ecosystems remains poorly studied. We assessed diversity, richness relative age divergences Schistidium (Grimmiaceae,...
Abstract The Sematophyllaceae s.l. (Sematophyllaceae+Pylaisiadelphaceae) is a family of pleurocarpous mosses that widely distributed throughout the globe, with centers diversity in tropical forests. circumscriptions and its genera have been unstable, due to reductions morphological complexity alternative weightings discrete traits. Based on sample spanning much generic family, we inferred phylogenetic relationships within from variation eight molecular markers all three genomes (nuclear,...
AbstractBase sequences of 376 bp chloroplast DNA and 521 nuclear ribosomal the newly described Platyhypnidium mutatum Ochyra & Vanderpoorten riparioides (Hedw.) Dixon are identical with exception one substitution in DNA. From these almost base sporophytes found both species, it is concluded that a somatic mutant latter species differing by bistratose lamina broader nerve. Previous to results, would have been placed genus Donchrichardsia because its vegetative morphological characters. It...
Abstract: Structure, variability, and molecular evolution of the trn T‐F region in Bryophyta (mosses liverworts) is analyzed based on about 200 sequences T‐L spacer L 5′ exon, 1000 intron, 800 3′ exon L‐F spacer, including comparisons lengths, GC contents, sequence similarities, functional elements. Mutations occurring exons, compensatory base pair changes, a transition anticodon Takakia lepidozioides, are discussed. All three non‐coding regions display mosaic structure highly variable...
Abstract Phylogenetic relationships and character evolution in the core Ptychanthoideae (Lejeuneaceae, Marchantiophyta), with a focus on Thysananthus , are assessed based molecular (plastid psbA–trnH, trnG, trnL–F, trnS–rps4 nrITS), morphological–anatomical, phytochemical data.

Most morphological characters currently used to distinguish genera homoplastic according ancestral...
Species boundaries are sometimes difficult to assess, especially when molecular data do not neatly match morphologically defined units. This study investigates the moss genus Isothecium, with special emphasis on Macaronesian populations. Morphological studies combined analysis of three rapidly evolving markers: nuclear internal transcribed spacer and plastid trnG trnL-trnF. The results morphological suggest that Isothecium is represented by five species in Macaronesia, including a new...
