Taxonomic validation of Saccharomycotina yeast genome assemblies through type-material-anchored BLAST-based average nucleotide identity analysis at the NCBI.

A 95% alignment-based ANI threshold in type-material-informed comparisons yields high concordance with declared Saccharomycotina species assignments for query-to-type genome matches.

• Why it matters: Genome assemblies need automated, reliable taxonomic checks, but misassigned or problematic references can undermine verification without expert review.
• What they did: Public Saccharomycotina assemblies were compared to type-material assemblies using an alignment-based ANI workflow, with thresholds set and results cross-checked against DNA-DNA hybridization and FastANI.
• The result: Alignment-based ANI strongly correlates with DNA-DNA reassociation and closely matches FastANI for highly alignable assemblies, enabling continuous quality control while flagging cases needing expert taxonomic review.
