Eleven yeast strains representing four novel species of the genus Starmerella were isolated from scarabs beetles collected in Nanyang, Henan Province, Central China. Phylogenetic analysis using combined sequences of the D1/D2 domains of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) regions placed all the novel species in a clade distinct from the other known species in the clade representing the members of the genus Starmerella. These novel species differed from each other or their closest known species by more than 4.

During a survey of yeasts associated with insects in Central China's natural ecosystems, 116 yeast strains were isolated from the gut of adult insects in two families and from one beetle larva. Among the yeasts isolated in this study, 102 strains were identified as 20 known species in the class Saccharomycetes. The remaining 14 strains were identified as representing five novel species in the Lodderomyces clade based on the combined sequences of the D1/D2 domains of the LSU rRNA gene and the internal transcribed spacer (ITS) regions, as well as other taxonomic characteristics.

These strains formed two hat-shaped ascospores in conjugated and deliquescent asci. Multilocus phylogenetic analysis that included the nearly complete small subunit (SSU), the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit (LSU) rDNAs, as well as RNA polymerase II largest subunit (RPB1) gene demonstrated that these strains represent a novel yeast species belonging to the genus Scheffersomyces.

Methods: We searched for articles in MEDLINE via PubMed, EMBASE, HuGE Navigator, CNKI, and Wanfang databases and calculated odds ratios (ORs) with 95% confidence intervals (CIs) to determine the strength of associations in fixed- or random-effects models.
Results: We included 21 articles in the meta-analysis: 17 reports of ADIPOQ rs2241766 with 3628 cases and 3000 controls and 8 of rs266729 with 2021 cases and 2226 controls.

Three strains of a novel species of ascomycetous yeast were isolated from the beetle species Anomala corpulenta (Scarabaeoidea) collected from the Baotianman and Funiu Mountains of China. These strains produced conjugated asci with a single coiled ascospore. Phylogenetic analysis of the combined sequences of the D1/D2 domains of the large subunit rRNA gene and internal transcribed spacer regions demonstrated that the three strains were closely related to Nematodospora valgi and an undescribed yeast strain, 13Y231.

Sequence analysis of the D1/D2 domains of the large subunit (LSU) rRNA gene revealed that these species are members of the Wickerhamiella clade. These three novel species have a greater than 2.

These strains formed two elongated ascospores, which were tapered and curved at the ends in persistent asci. Sequence analyses of the D1/D2 domains of the large subunit (LSU) and small subunit (SSU) rRNA genes showed that these new strains represent a phylogenetically distinct species in the Spathaspora clade.

These strains produced unconjugated asci with one or two ellipsoidal to elongate ascospores in a persistent ascus. Phylogenetic analysis of the D1/D2 domains of the LSU rRNA gene sequences indicated that the isolates represent two novel sexual species in the Candida/Lodderomyces clade.

Methods: A total of 1842 T2DM cases (507 newly diagnosed cases and 1335 previously diagnosed cases) and 7777 controls were included in this case-control study. PCR-RFLP was conducted to detect the genotype of the two single nucleotide polymorphisms (SNPs).

Seven yeast strains were isolated from the gut of insect larvae and decayed wood, which were collected from three localities near Nanyang, Henan Province, China. These strains were identified as two novel species through comparison of sequences in the D1/D2 domains of the large subunit (LSU) rRNA gene and other taxonomic characteristics.

Two strains of an asexual cellobiose-fermenting yeast species were isolated from rotten wood samples collected in Funiu Mountain Nature Reserve in Henan Province, central China. Molecular phylogenetic analysis that included the nearly complete small subunit (SSU), the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit (LSU) rDNA showed that these strains belonged to the Candida kruisii clade, with Candida kruisii and Candida cretensis as their closest phylogenetic neighbours.
