Oyster mushrooms you can grow on cardboard in your kitchen closet are at the frontier of a genetic research puzzle — scientists can read their DNA but still struggle to rewrite it, which means faster-fruiting, disease-resistant strains for home cultivators are still years away.
Researchers compiled everything we know about the genetics of oyster mushrooms — a group of edible fungi popular worldwide. They found that while scientists have decoded the full DNA of 14 different species, actually using that information to change how the mushrooms grow or behave is still very difficult. New gene-editing tools like CRISPR, which work well in plants and animals, haven't yet been reliably applied to most of these mushrooms.
Key Findings
Whole genome sequences are now available for 14 Pleurotus species, providing a growing reference library for functional gene discovery.
CRISPR/Cas9 gene editing has only been successfully applied to 2 species (P. eryngii and P. ostreatus) due to difficulties establishing transformation systems and low homologous recombination efficiency.
RNAi and gene overexpression techniques are well-established and routinely used across most Pleurotus species, making them the current workhorse tools for functional research.
chevron_right Technical Summary
Scientists reviewed the state of genetic research on Pleurotus mushrooms (oyster and king oyster mushrooms), finding that while genome sequencing has expanded greatly, tools for actually editing those genes remain limited to just two species. This review maps what's possible now and where the field needs to go next.

Pleurotus is a genus of gilled mushrooms with species known as oyster, abalone, or tree mushrooms. It includes some of the most commonly cultivated edible mushrooms in the world, such as P. ostreatus. Additionally, some species have been used in the mycoremediation of pollutants.
