초록

세계적 멸종위기종인 따오기(Nipponia nippon)는 2008년 10월에 중국에서 1쌍이 도입된 후 한국최초로 인공번식에 성공하였다. 본 연구는 따오기의 sex-related gene과 Chromodomain Helicase DNA Binding Protein gene (CHD gene)을 가지고 polymerase chain reaction (PCR)을 수행하여 새로 태어난 따오기 유조의 성별을 확인하고자 하였다. 본 연구에서는 따오기의 성별 확인을 위해 PCR후 제한효소의 처리 방법과 P2과 P8를 이용한 PCR 방법을 실시하였을 때 더 정확한 결과가 나타남을 알 수 있었다. 그리고 CHD gene의 염기서열을 선행연구와 비교해 본 결과, 암컷의 염기서열에서 1~2 base pairs 차이가 나타남을 알 수 있었다.

In October 2008, a pair of Crested ibis Nipponia nippon, an endangered avian species in the world, was donated to Korea from China. They have since been the subject of a successful program to incubate chicks for the first time in South Korea. This study was carried out to determine the sex of chicks from the Crested ibis through polymerase chain reaction (PCR) using the sex-related gene and the chromodomain helicase DNA binding protein (CHD) gene. The result of the CHD gene, which was used with a single set of primers and a restriction enzyme treatment after the PCR process, was more accurate in identifying the gender of the Crested ibis. In addition, we compared the CHD gene sequences with the previously reported sequences and found 1~2 different bases between females (CI2, CI4, CI5, and CI6) than in studies previously reporting female sequences.
