“…The development of new molecular identification tools for bryophytes would improve the ecological studies and help in investigating the impact of global climate change. Recently the closely related Dicranum scoparium species were collected from the high Arctic Archipelago of Svalbard resolved by combining five plastid regions (rpoB, trnH-psbA, trnL-trnF, rps4-trnT, rps19-rpl2) and the nuclear ribosomal ITS region (20). DNA barcoding of moss species diversity such as Schistidium species colonizing modern building surfaces showed morphological differences, and suggested cryptic taxa (21).…”

Plant identification is a crucial and routine taxonomic procedure in order to understand and conserve the biodiversity. Anthropogenic activity, pollution, deforestation, and exploitation of natural resources have been threatening to the plant biodiversity. Unfortunately, the major concern of traditional identification of plants is the gradual declined number of taxonomic expertise and lack of tools which accurately discriminate plant seeds, plant parts and seedling, and herbal adulterant. Presently, it is of utmost importance that plant biodiversity to be preserved. To overcome this issues the advent of molecular marker based technique which utilized short fragment of DNA and correctly assign plant taxa to their taxonomic group, called as DNA barcoding. First time, single marker based taxon identification successfully implemented to an animal taxa using mitochondrial cytochrome I (COI) gene fragment. However, Plant DNA barcoding is more complex and it often requires more than one set of DNA markers. In the present review, we have compiled the recent progress of plant DNA barcoding in various taxonomic groups and utility of plastids and nuclear DNA based markers for plant identification.

“…DNA markers may be vital for accurately identifying Arctic bryophyte species (Lang et al 2014), especially when only diaspores are sampled, and can provide an overall picture of the origin of diaspores and populations. A complete DNA barcode database for Arctic and sub-Arctic bryophytes is required in order to accurately identify bryophyte diaspores present in environmental samples taken from snow or air, for example.…”

“…Improvements have been made concerning taxonomy of some Arctic bryophyte species (Hesse et al 2012); however, molecular studies are still needed for most Arctic bryophyte taxa to assess species circumscriptions. DNA barcoding tools (e.g., Hassel et al 2013;Stech et al 2013;Lang et al 2014) would likely standardize identification across the Arctic and combined with other genetic tools promote the study of migration, mating system, and patterns of genetic diversity within consistent taxonomic entities (Zartman et al 2006;McDaniel et al 2013aMcDaniel et al , 2013bMagdy et al 2016). …”

The development of evidence-based international strategies for the conservation and management of Arctic ecosystems in the face of climate change is hindered by critical knowledge gaps in Arctic floristic diversity and evolution. Particularly poorly studied are the bryophytes, which dominate the vegetation across vast areas of the Arctic and consequently play an important role in global biogeochemical cycles. Currently, much of what is known about Arctic floristic evolution is based on studies of vascular plants. Bryophytes, however, possess a number of features, such as poikilohydry, totipotency, several reproductive strategies, and the ability to disperse through microscopic diaspores, that may cause their responses to Arctic environments to differ from those of the vascular plants. Here we discuss several priority areas identified in the Arctic Council's "Arctic Biodiversity Assessment" that are necessary to illuminate patterns of Arctic bryophyte evolution and diversity, including dispersal, glacial refugia, local adaptation, and ecological interactions with bryophyte-associated microbiomes. A survey of digitally available herbarium data archived in the largest online aggregate, GBIF, across the Arctic to boreal zones indicates that sampling coverage of mosses is heterogeneous and relatively sparse in the Arctic sensu stricto. A coordinated international effort across the Arctic will be necessary to address knowledge gaps in Arctic bryophyte diversity and evolution in the context of ongoing climate change.Key words: biodiversity, dispersal, local adaptation, microbiome, phylogeography.

“…Eleven specimens of D. groenlandicum also cover Russia from its western border to Sakhalin in the East, and one specimen from Alaska was included (as no fresh material from Chukotka was available). The obtained sequences from these specimens were embedded to the data previously obtained by ourselves, as well as by other authors (Tubanova et al, 2010;Tubanova & Ignatova, 2011;Ignatova et al, 2015;Lang et al, 2014).…”

Distinction between Dicranum elongatum and D. groenlandicum was tested with molecular markers. Molecular phylogenetic analysis of nuclear ITS1-2 and chloroplast trnL-F sequences confirmed separate status of these species. The importance of width of costa for their delimitation was confirmed; however, cell length in distal and proximal parts of leaves appeared to be variable in both species. Leaf apex in D. groenlandicum is occasionally acute and margins are denticulate near apex in some specimens, contrary to the statement in most handbooks that they are invariably entire and that leaf apex is always obtuse. Dicranum elongatum and D. groenlandicum have similar distribution in Russia. They occur in northern provinces of European Russia and Urals, are known by few records in the Caucasus and are widely distributed in Asian Russia, from Arctic regions to Southern Siberia. Резюме С помощью молекулярных маркеров уточнены границы между Dicranum elongatum и D. groenlandicum. Анализ последовательностей ITS1-2 ядерной и trnL-F хлоропластной ДНК подтвердил их видовую самостоятельность. Было показано, что наиболее устойчивым морфо-логическим признаком, позволяющим разграничивать эти виды, является ширина жилки, тогда как длина клеток в верхней и нижней части листа варьирует у обоих видов. Верхушка листа D. groenlandicum может быть заостренной, а края в верхней части листа иногда бывают пильчатыми, вопреки распространенному во многих определителях утверждению, что у этого вида верхушка всегда туповатая, а края листа цельные. Dicranum elongatum и D. groenlandicum имеют сходное распространение в России. В европейской части они встречаются в северных областях и на Урале и известны по единичным находкам на Кавказе, а в Азиатской части оба вида широко распро-странены от Арктики до гор южной Сибири.
