Summary: The genus Clostridium is diverse and includes species like C. cocleatum, C. ramosum, C. spiroforme, and C. saccharogumia. These species form a distinct cluster within the family Coprobacillaceae in the order Erysipelotrichales. Based on phylogenetic, genomic, phenotypic, and chemotaxonomic information, it is proposed that these species be transferred to a new genus called Thomasclavelia.

Summary: Using genome-based analysis, three monophyletic clusters were identified within the genus Acidovorax, which were not reflected in the 16S rRNA gene-based phylogenetic tree. Digital DNA-DNA hybridization and nucleotide identity values further confirmed the species arrangements within the genus. Additionally, Acidovorax antarcticus was found to be more closely related to members of the genus Comamonas. Therefore, it is proposed to divide the current genus Acidovorax into the emended genus Acidovorax and two novel genera, Paracidovorax gen. nov. and Paenacidovorax gen. nov., and transfer Acidovorax antarcticus to the genus Comamonas as Comamonas antarctica comb. nov.

Summary: In the era of increasingly complex consumer lifestyles, the conventional baker's yeast is facing some issues, prompting the need to search for alternative yeasts. Through evolutionary engineering, potential alternative baker's yeasts were identified and their baking traits were improved. The evolved yeasts showed improved ability to withstand baking associated stresses and produced bread with higher loaf volume.

Summary: Asexually reproducing fungi play significant roles in ecosystems and have implications for plant and animal health, food production, biotechnology, and medicine. However, the diversity and extent of asexually reproducing taxa are not well-known. Recent reports suggest that there may be more asexual fungi than sexually-reproducing ones. Evaluating the diversity of different types of fungi, such as speciose and pleomorphic taxa, as well as those from less studied life modes and biodiversity-rich areas, is necessary to obtain more reliable estimates.

Summary: This study investigates the evolutionary relationships among Saccharomycotina yeasts from a mitochondrial genomic perspective. The findings suggest that the diversity in mitochondrial genome size is a result of random processes such as genetic recombination and intron mobility. The study also reveals conserved syntenic units and rearrangements that correlate with major evolutionary events.

Summary: The systematic position of 16 yeast strains isolated from different countries were evaluated using various analyses, leading to the discovery of a new yeast species and the reassignment of two existing species. The close relationship between certain yeast species was unexpected and required further clarification. Morphological and physiological characteristics were shared among the three yeast species. The findings contribute to a better understanding of yeast taxonomy and evolution.

Summary: A new species of the yeast genus Blastobotrys was discovered in house dust, with similar species detected globally in various substrates. The new species, Blastobotrys davincii, was classified based on morphological, phylogenetic, and physiological characters. The preferred name for the new species is still under debate, but Blastobotrys is argued to be more suitable than Trichomonascus. A nomenclatural review and accepted species list for Blastobotrys/Trichomonascus clade were also provided.

Summary: Examining the changes in order and arrangement of homologous genes is crucial for understanding genome evolution in eukaryotes. This study analyzed 120 high quality genomes of budding yeast species to investigate the evolution of genome organization and compared it with animals and plants. The decay of macrosynteny and microsynteny was strongly associated with evolutionary divergence in the budding yeast major clades. However, the microsynteny of many genes, especially in metabolic clusters, was deeply conserved within major clades and across subphylum. Comparing genomes with similar divergence times, budding yeasts showed lower conservation in macrosynteny compared to animals and filamentous fungi, but higher conservation than angiosperms. In contrast, they exhibited similar levels of microsynteny conservation with mammals, while angiosperms had very low conservation.

Summary: The subphylum Saccharomycotina is a diverse lineage within the fungal phylum Ascomycota, consisting of over 1,200 known species divided into 16 families, one order, and one class. It exhibits high genomic diversity and includes both opportunistic human pathogens and species important in biotechnological applications. However, the biotechnological potential of most yeast species remains unexplored. The current classification of Saccharomycotina as a single class and order underestimates its diversity, and an updated classification with seven classes and 12 orders is proposed based on genome content analysis and phylogenetic relationships.
