A survey of the moss flora of the southernmost part of the Russian Primorsky Territory yielded several intriguing taxa, whose identity is assessed herein based on an integrative morpho-molecular approach. was previously known in inland Asia only from the Sino-Himalayan region and the new locality is distant from the earlier known ones to ca. 3000 km.

An analysis of the phylogenetic affinities of the species based on nuclear ITS and plastid L-F regions showed that it is resolved within the clade corresponding to sect.

The collected plants are described here as sp. nov.

- Rf1 is a crucial gene for restoring male fertility in sunflowers, but its exact location and function have yet to be fully determined.
- Researchers have developed two new markers based on single nucleotide polymorphisms (SNPs) linked to the Rf1 gene, which have proven effective for genotyping various sunflower accessions and populations.
- The study successfully pinpointed the Rf1 gene's location to a region of 59 Kb, narrowing down candidate genes but suggesting further analysis may uncover additional candidates not present in the reference genome of cytoplasmic male sterility maintainer lines.
Article Synopsis
- Genus s.l. has been split into multiple genera, but the taxonomic and phylogenetic relationships of some former members remain unclear.
- A specific taxon, nom. illegit. ≡, which is endemic to Central Dagestan, was not included in prior studies and lacks clear phylogenetic relationships.
- Molecular phylogenetic analysis revealed that the newly established genus contains related species that are morphologically distinct, along with detailed distribution information for the newly categorized taxa.
Article Synopsis
- The study investigates subaquatic species of the genus Pylaisiaceae, revealing eight distinct species utilizing molecular and morphological analyses and distribution modeling.
- Previous classifications were found to overlook significant genetic diversity within these plants, with separate lineages identified in temperate Europe, eastern North America, and eastern Asia.
- The research underlines the rich bryophyte diversity in non-tropical Asia and establishes the need for new species descriptions based on distinct phylogenetic lineages and morphological characteristics.
The results of a molecular genetic study of agg. using two plastid markers ( and ) and a nuclear ITS marker suggested that this group comprises a number of relatively young and incompletely differentiated species widely distributed in Northern Eurasia. The sequences were analyzed using tree-based (maximum likelihood) and network-based (statistical parsimony network) approaches.

- The mitochondrial genome of moss was sequenced with Spades, containing 100,342 base pairs and a gene set similar to other bryophytes.
- The genome includes 66 genes, including rRNAs, tRNAs, and mitochondrial proteins, but notably lacks a functional gene found in most other bryophyte mitogenomes.
- The study suggests the independent evolution of certain genes and highlights the potential of the moss mitochondrial genome as a phylogenetic marker, supported by a phylogenetic tree based on 33 protein coding sequences from 40 bryophyte species.
