Abstract

The Cobitis hankugensis-Iksookimia longicorpa complex from Korea has been presumed to be a unisexual lineage, originating from C. hankugensis and I. longicorpa and having almost all females. Recently, it was confirmed that the complex consisted of one diploid and two triploid complexes. From observation of their oocyte envelopes, three forms could be classified: a villous projection in I. longicorpa, a granular one in C. hankugensis and two triploid complexes, and a granule with villous one in the diploid complex. Even within the same granular projection, they showed specific features in length and density number from each other. These architectures are first observed in cobitid complexes and may playa role in identification of diploids and triploids.

기름종개와 왕종개로부터 기원한 단성생식집단인 Cobitis hankugensis-Iksookimia longicorpa complex는 대부분 암컷으로만 구성되어 있으며 최근에 1종류의 2배체와 2종류의 3배체집단이 확인되었다. 이들의 난막구조를 조사한 결과 3가지 종류로 구분될 수 있었다. 융모형은 이들의 부모종인 왕종개에서 확인되었으며, 과립형은 기름종개와 3배체집단, 그리고 과립을 가진 융모형은 2배체집단에서 나타났다. 특히 과립형을 가지는 3집단에서는 그들의 길이와 밀도에서 서로 차이를 보였다. 이러한 구조들은 cobitid complex에서 처음 보고될 뿐 아니라 2배체, 3배체 complex집단을 분류하는 데 이용될 수 있다.
