초록

복잡한 진핵생물에서의 물리적 지도 작성이나 기능해석에 효모인공염색체(YAC)를 이용하기 위해서는 원하는 target region의 인공염색체화 및 single-copy인 YAC의 복제수를 늘이는 것이 요구된다. 본 연구에서는 YAC manipulation system에 복제수 증폭시스템(copy number amplification system)을 도입한 Simultaneous YAC Manipulation-Amplification (SYMA) system을 구축하였다. 식물염색체를 가진 YAC clone의 splitting과 증폭을 위해 conditional centromere와 thymidine kinase (TK) 유전자를 가진 pBGTK plasmid를 구축하였고, splitting fragment의 PCR을 위한 주형으로 사용하였다. 590 kb의 YAC clone은 splitting과 동시에 copy number amplification element를 가진 100 kb YAC와 490 kb YAC로 분리되었고, 100 kb YAC는 유도기질로 3 mg/ml sulfanilamide와 $50\;{\mu}g/ml$ methotrexate (S3/M50)의 첨가에 의해 14.4배로 그 복제수가 증가하였음을 확인할 수 있었다.

Artificial chromosome manipulation and amplification of single-copy yeast artificial chromosome (YAC) are usually required in order to use YACs for applications such as physical mapping and functional analysis in eukaryotes. We designed and implemented a Simultaneous YAC Manipulation-Amplification (SYMA) system that combines the copy number amplification system of YAC with a convenient YAC manipulation system. To achieve the desired split and to amplify a YAC clone-harboring plant chromosome, a pBGTK plasmid containing a conditional centromere and thymidine kinase (TK) gene was constructed as a template to amplify the splitting fragment via PCR. By splitting, new 490-kb and 100-kb split YACs containing the elements for copy number amplification were simultaneously generated from a 590-kb YAC clone. The 100-kb split YAC was then successfully amplified 14.4-fold by adding 3 mg/ml sulfanilamide and $50\;{\mu}g/ml$ methotrexate (S3/M50) as inducing substances.
