Ribosomal RNA 유전자를 이용한 한국산 세포성 점균의 분자생물학적 분류(Ⅰ)

Abstract

Thirty three species of cellular slime molds have been isolated in South Korea. They have been identified by the stages of the life cycles and morphological characteristics such as color, size, branch, polar granule, etc. However, this methods were often insufficient to classify the very similar species. In this context, this study was designed to suggest new criterion and apply it to eleven species : Dictyostelium dimigraformum, D. giganteum, D. discoideum, D. pupureum, D. minutum, D. aureostipes, D. polycephalum, Polysphondylium violaceum, D. cαndidum, P. pallidum, and P. tenuissimum Results showed that classification by rRNA gene sequencing was similar to that by previous methods, and that the classification could be proper method for distinguishing between very closed species.
