Annamia dubia sp. nov. with a description of a new family, Geminocystaceae fam. nov. (Cyanobacteria)
Our environmental DNA analysis identified Annamia-like operational taxonomic units (OTUs) from Lake Kasumigaura, Japan every summer season during the period June 2012-May 2015. A strain Kasumigaura that agreed with an OTU (NIES-4383) was established a cell-sorting machine. Based on differences in morphology and 16S rRNA sequences, new taxon is described: Annamia dubia Tuji, Yamaguchi et Niiyama...
To determine the occurrence and genetic diversity of Sapelovirus A (SV-A) in diarrhea and non-diarrhea feces of Korean pigs, 110 specimens from different age groups of pigs in the same farm were analyzed by RT-nested PCR. SV-As were detected in 60% of both diarrhea and non-diarrhea specimens regardless of age groups with primer pairs for 2C region, in which all diarrhea samples were co-infected...
Great progress has been made in recent years on taxonomy of brown rot polypores based phylogenetical evidence, mainly Daeadalea within Fomitopsidaceae. However, the relations Fomitopsidaceae family remain unresolved. Some neotropical species Daedalea were never included molecular phylogenetic analyses, such as D. aethalodes, ryvardeniana, and south American specimens modesta. To clarify relatio...
In spite of the importance of chemical signals (pheromones) in the reproductive behaviour of lizards, only a few studies have examined the role of specific chemical compounds as sexual signals. The secreted chemicals vary widely between species but whether this variation reflects phylogenetic or environmental differences remains unclear. Based on mass spectra, obtained by GC-MS, we found 40 lip...
This study reveals the concordance, or lack thereof, between morphological and phylogenetic species concepts within Entoloma subg. Leptonia in boreal-temperate Eurasia, combining a critical morphological examination with a multigene phylogeny based on nrITS, nrLSU and mtSSU sequences. A total of 16 taxa was investigated. Emended concepts of subg. Leptonia and sect. Leptonia as well as the new s...
