77 New Ascomycete Yeast Species from China with Phylogenetic Data

Two decades of yeast diversity surveys in China yielded 195 isolates, leading to the proposal of 77 new species and 2 new genera. The dataset likely contains phylogenetic analyses based on LSU D1/D2 and ITS rDNA sequences, with species delimitation using Average Nucleotide Identity (ANI). It was authored by huihui zhu and published on figshare under a CC-BY-4.0 license.

Use Cases

• Taxonomic classification of yeast species based on phylogenetic analyses of LSU and ITS sequences
• Comparative biodiversity studies of ascomycetes in China versus other regions
• Training models for species delimitation using ANI values
• Exploring the distribution of yeast genera within Saccharomycotina and Taphrinomycotina

Strengths

• 77 new species described, providing a substantial update to yeast taxonomy
• 195 isolates collected over two decades, suggesting a longitudinal sampling effort
• Analysis includes two key genetic regions (LSU D1/D2 and ITS) and ANI for species delimitation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is small (846.6 KB), indicating limited scope or highly compressed data
