초록
Virus 이병(罹病) 느타리버섯 (Pleurotus spp.)으로부터 이중나선(二重螺腺) ribo 핵산(核酸 )(ds RNA)을 분리(分離)하였다. Ds RNA 는 8100 base pairs(bp)의 큰 band 와 2170, 2120, 1980 및 1840 bp의 4개 작은 band로 이루어졌다. Ds RNA 분석법(分析法)으로 느타리버섯의 Virus 이병여부(罹病與否)를 조사(調査)한 결과(結果) 균사생장(菌絲生長)이 부진(不振)하고 세균성(細菌性) 갈색(褐色) 부패병(腐敗病) 등(等)에 이병(罹病)되고 이상자실체(異常子實體)를 형성(形成)하는 느타리버섯으로부터 Virus 이병(罹病)을 확인(確因)하였으나 건전(健全)버섯으로부터는 ds RNA를 분리(分離)하지 못하였다. 이 병(病)은 해외(海外)로부터 전래(傳來)한 것으로 보인다. Ds RNA 는 저농도염류액(底濃度鹽類液) (0.1XSSC)에서 RNase A 에 용해(鎔解)되었으며
The experiment was performed to find out the possibilities to detect virus infection in oyster mushrooms, Pleurotus species by analysis of doublestranded ribonucleic acid (ds RNA). Ds RNA segments were extracted from virus infected isolates which grew abnormally. But virus free isolates didn't show any ds RNA segments. The ds RNA was consisted of one large segment of 8100 base pairs (bp) and 4 smaller segments with 2170, 2120, 1980 and 1984 bp. Whereas, cell free virus particles showed only one larger ds RNA segment. The ds RNA was dissolved by RNase A in low salt, 0.1 M SSC and melted at
