This study was carried out to characterize virus-like particles (VLPs) in Pleurotus ostreatus. The white and the dark gray mutants frequently observed in mushroom farms of Pleurotus ostreatus (Wonhyeong-neutari). A 5.8kb segments of dsRNA was detected only in the white mutants but not in the dark gray mutants. The VLPs were purified from the fruit bodies by Polyethylene Glycol (PEG) and ultracentrifugation. Electron microscopy analysis showed that VLPs were isometric about 14, 20∼45nm in diameter. Further study is needed to reveal the morphological and yield variations of mushroom strains including VLPs observed in the mushroom farms. Also it is needed to maintain fundamental research for taxonomy, diagnosis, and physiology of VLPs in the mushroom strains.
