TL;DR: Although family, genus, or species identifications were not possible for most groups, spores of a few genera and species were distinctive and showed greatest differences between the North Slope tundra and other vegetation types.
Abstract: This study describes (i) spore morphology of 121 Alaskan species of true moss (Bryidae) and (ii) percentages of Bryidae and Sphagnum spores in mud-water interface samples from 46 Alaskan lakes and a late-Quaternary sediment core from Idavain Lake in southwestern Alaska. Bryidae spores were collected from herbarium specimens, prepared by standard palynological chemical treatment and described under light microscopy. An identification key based on spore shape, wall structure, and size recognized 11 major morphological groups. Although family, genus, or species identifications were not possible for most groups, spores of a few genera and species were distinctive. Bryidae spores occurred in 80% of the modern sediment samples, representing boreal forest and three areas of tundra (North Slope, Seward Peninsula, and southwestern Alaska). Bryidae and Sphagnum spore percentages showed greatest differences between the North Slope tundra and other vegetation types, whereas pollen percentages distinguished boreal for...

TL;DR: In this article, the authors used a PCR-based approach to probe genomic DNA samples from representatives of evolutionary distant Bryophyta taxa, namely, class Bryopsida (subclasses Bryidae and Dicranidae) and class Sphagnopsida.
Abstract: Transacting siRNA loci (TAS3-like) of a particular plant species are usually represented by several gene families. PCR-based approach was used as a phylogenetic profiling tool to probe genomic DNA samples from representatives of evolutionary distant Bryophyta taxa, namely, class Bryopsida (subclasses Bryidae and Dicranidae) and class Sphagnopsida. We found relatives of all four Physcomitrella patens (subclass Funariidae) TAS3-like loci in subclasses Bryidae and Dicranidae. Only representatives of subclass Bryidae encoded TAS3-like genes belonging to P. patens TAS3a and TAS3d families. On the other hand, only the members of order Grimmiales (subclass Dicranidae) encoded gene relatives of P. patens TAS3c family. These data indicate that moss ta-siRNA families have been long conserved during land plant evolution. However, P. patens TAS3-like loci were detected neither in two Sphagnum species from the earliest diverged moss class Sphagnopsida, nor in the Selaginella kraussiana from the earliest extant tracheophyta lineage, Lycopodiopsida.

TL;DR: The complete chloroplast genome of the moss Myurella julacea (Schwägr.) Schimp was found to have a typical quadripartite structure, and clustered into a clade with other Hypnales groups with high bootstrap support.
Abstract: Here, we report the complete chloroplast (cp) genome of the moss Myurella julacea (Schwagr.) Schimp. We found that the total length of the M. julacea complete cp genome was 124,457 base pairs (bp) ...

TL;DR: The complete mitochondrial genome of Myurella julacea (Schwagr.) Schimp was reported in this paper, with a genome size of 104,979 bp.
Abstract: The present study reports the complete mitochondrial genome of Myurella julacea (Schwagr.) Schimp. (GenBank accession number MT850126); the genome size was 104,979 bp. The gene arrangement was foun...
