Pleurotus Ostreatus PC9.15 Strain Genome Annotation Table

A genome annotation table for the PC9.15 congenic strain of the edible oyster mushroom Pleurotus ostreatus. The dataset, created by Yi-Yun Lee and last updated in April 2026, details the genomic differences, specifically at the matA and matB mating-type loci, between this strain and its parent PC9. It is a 20.1 MB Excel file.

Use Cases

• Compare gene annotations between the PC9.15 and PC9 strains to identify loci-specific variations.
• Analyze the structure and allele composition of the multiallelic matA and matB mating-type loci.
• Use the annotated genome as a reference for genetic mapping or functional studies in Pleurotus ostreatus.
• Investigate genomic similarity metrics, such as the reported 99% similarity between congenic strains.

Strengths

• High-quality genome assembly for the PC9.15 strain, confirmed as 99% similar to the PC9 background.
• Data characterizes 11 A and 12 B alleles across twelve haplotypes, confirming multiallelic mating loci.
• Openly licensed under CC-BY-4.0 for broad reuse.

Limitations

• The 20.1 MB file size suggests a limited genomic scope, likely focused on annotation tables rather than raw sequence data.
• Specific row counts and column details for the annotation table are unknown, limiting assessment of comprehensiveness.
• Data is specific to laboratory strains (PC9, PC15, PC9.15), not necessarily representative of wild Pleurotus populations.
