이온화방사선에 의한 느타리버섯(Rleurotus ostreatus)의 ITS2 염기서열 변화

rDNA의 ITS2(internal transcribed spacer 2)부위에 대한 이온화방사선(gamma-ray)의 영향을 알아보기 위해서 감마선을 조사한 느타리버섯(Pleurotus ostreatus)의 5종의 변이중에서 ITS2의 염기서열을 결정하였다. ITS2의 염기서열은 1 kGy 조사군(PO-5, PO-6, PO-15와 PO-16)에서 변화되지 않았으나, 2kGy 조사군(PO-14)에서는 1개의 염기가 치환되었다. RAPD(ramdomly amplified polymorphic DNA) 양상에 의한 유전유사도의 변화가 다양하였고 섬유소성 고체검정 배지에서도 다양한 생장특성을 나타내었다. 본 연구결과는 ITS염기서열이 이온화 방사선에 의해 선량의존적으로 변화될 수 있음을 시사해 주었다.

In order to test the degradability upon organic compounds and self-clarification in Kum River area, analysis upon physico-chemical factors (pH, DO, BOD), total haterotrophic bacteria, population of bacteria decomposing specific organic compounds, phosphatase activity, the amount of chlorophyll, DNA and polyphosphate were carried out during the period from June 1990 to April 1991. From the result of physico-chemical factor analysis, self-purification of Daechong reservoir (Station 1) and its outflow (Station 2) was recognized periodically, while organic pollution at Gapchun stream (Station 3) was serious, and the middlestream of Kum River (Station 4) might be self-clarified gradually. In Daechong reservoir and its outflow (that is, the upstream of Kum River), cellulolytic and amylolytic bacteria were distributed dominantly. Considering the even distribution of cellulolytic, amylolytic, lipolytic and proteolytic bacteria in Gapchun stream and the middlestream of Kum River, inflow of various organic compounds could be made an estimate. Cellulolytic bacteria were dominantly distributed in all areas of Kum River in July specifically. Also population densities of E. coli and cadimum resistant bacteria were higher in Gapchun stream and the middlestream of Kum River in others. It is postulated that acid phosphatase acted chiefly on the internal growth of community, on the other hand, alkaline phosphatase acted on supplying phosphate group to environment. The amounts of poly-P were relatively high temporally before the blooming of phytoplankton. It was also high in the polluted area. That the relative ratios of poly-P to DNA or to chlorophyll can be applied usefully for the biological index checking the unbalanced and eutrophicated state of nutrition in environment.
