Pleurotus Ostreatus Mating-Type Loci and Congenic Strain Genomes

Genomic data for the edible oyster mushroom Pleurotus ostreatus, focusing on the multiallelic mating-type loci matA and matB. The dataset includes information on 11 A and 12 B alleles identified across twelve haplotypes from strains including PC9, PC15, and the congenic strain PC9.15. Yi-Yun Lee authored this dataset, which was last updated in April 2026.

Use Cases

• Analyze the distribution and diversity of 11 matA and 12 matB alleles across twelve P. ostreatus haplotypes.
• Compare genome assemblies between the PC9 and PC9.15 congenic strains to identify differences localized to the mating-type loci.
• Study the genetic background effects by comparing physiological traits of the monokaryotic strains PC9 and PC15.
• Validate the high similarity (99%) between the PC9 and PC9.15 genomes outside the introgressed matA and matB regions.

Strengths

• Identifies 11 A and 12 B alleles across twelve distinct haplotypes, confirming multiallelic nature.
• Provides a high-quality, contiguous genome assembly for the congenic strain PC9.15.
• Data is openly shared under a CC-BY-4.0 license, facilitating reuse.

Limitations

• The dataset is very small at 9.5 KB, indicating limited genomic sequence data or a highly focused table.
• Scope is restricted to a few laboratory strains (PC9, PC15, PC9.15, N001), not representative of wild P. ostreatus diversity.
• The XLS format may not be ideal for large-scale genomic sequence analysis common in bioinformatics.
