Rejection of the concept of hemiurid genus Pulmovermis (Digenea: Hemiuridae) and other taxonomic propositions: new morphological and molecular data regarding Lecithochirium cyanovitellosum (Coil and Kuntz, 1960) Urabe and Sokolov, comb. nov. (formerly Pulmovermis cyanovitellosus).

Pulmovermis cyanovitellosus Coil and Kuntz, 1960 is a species of hemiurid trematode that localizes in the lung of sea snakes, an unusual trait for this group of parasites. Recent molecular phylogenetic studies based on 28S rRNA gene sequences have shown that this species is closely related to members of the genus Lecithochirium Lühe, 1901. This finding is unexpected given that Pulmovermis Coil and Kuntz, 1960 and Lecithochirium are currently classified in different subfamilies of Hemiuridae (Pulmoverminae Sandars, 1961 vs.

Inonotus obliquus (Chaga mushroom) is a large medicinal and edible fungus that contains a wealth of bioactive terpenoids. However, the detection of certain low-abundance sesquiterpenoids remains a challenge due to limitations in extraction and analytical techniques. Furthermore, the synthase genes responsible for the biosynthesis of the identified terpenoids have not yet been clearly elucidated.

Four main classes of introns (group I, group II, spliceosomal, and archaeal) have been reported for all major types of RNA from nuclei and organelles of a wide range of taxa. When and how introns inserted within the genic regions of genomes, however, is often unclear. Introns were examined from Archaea, Bacteria, and Eukarya.

Two strains of , identified based on morphology and phylogenetic analysis, were isolated from rocky desertification soils in Yunnan province. Phylogenetic analyses inferred from three loci (the internal transcribed spacer of the nuclear ribosomal RNA gene, β-tubulin and RNA polymerase II second-largest subunit) showed that the two strains formed a single clade and were introduced as a new species of , is characterized by having ampulliform or broadly fusiform conidiogenous cells and dark olivaceous-green, oblong-ellipsoidal conidia. Phylogenetically, is most closely related to , but it distinguishes the latter by longer and narrower conidia.

Mitochondrial genomes are a rich source of data for various downstream analyses such as population genetics, phylogeny, and systematics. Today it is possible to assemble rapidly large numbers of mitogenomes, mainly employing next-generation sequencing and third-generation sequencing. However, verification of the correctness of the generated sequences is often lacking, especially for noncoding, length-variable parts.
