Description
Ma and colleagues produced an improved chromosome-level genome in 2026 for the oyster mushroom Pleurotus ostreatus, strain CCMSSC 00389, a major farmed edible mushroom in China prized for nutrition and medicinal value. A clean genome map underpins breeding and trait research, and earlier versions were fragmented. Long-read sequencing let the team assemble the genome into full chromosomes and compare it with past releases.
The new assembly spans twelve pseudo-chromosomes and about forty million DNA letters, roughly a tenth larger than before, with pieces cut from over twenty-five hundred scaffolds to just twenty. A standard continuity score rose more than ninefold, average gene length grew, and the count of genes matched to public databases rose by over a thousand. Completeness checks found about 93 percent of expected conserved genes. The authors offer the assembly as a base for evolution, physiology, and molecular breeding work.
