초록

Polyphenol 화합물이 다량 함유된 식물종의 유연관계 분석이나 형질전환 유전자 확인 등을 위해 PCR을 이용할 경우 다량의 재료로부터 신속 간편하게 분리한 DNA를 이용할 수 있는 조건을 설정 하였다. 폴리페놀 함량이 높은 포도, 사과, 복분자와 같은 과수류에서 간편법에 의해 추출된 DNA를 이용한 PCR 반응액에 2%의 BLOTTO를 첨가함으로서 DNA의 재현적 증폭이 가능하였다. 간편 추출 DNA를 이용한 PCR에서 의 BLOTTO효과는 primer, 품종, 식물종에 관계없이 일반적으로 발현되었다. 상추의 형질전환 유전자 검색을 위한 PCR에서 도 BLOTTO 효과가 확인되었다. 따라서 PCR 반응액에 2% BLOTTO를 첨가하면 간편 법 에 의해 추출된 polyphenol 화합물 고함유 식물종의 DNA를 이용하여서도 PCR에 의한 유전배경 및 특정 유전자의 대량 신속 분석이 가능할 것이다.

Polymerase chain reaction (PCR) is used in a wide array of researches in plant molecular genetics and breeding. However, considerable time and cost are still required for the preparation of DNA suitable for reliable PCR results, especially in plant species containing high amounts of polyphenols. To reduce time and effort for PCR-based analysis, a simplified but reliable method was developed by a combinational employment of a simple and fast DNA extraction procedure and BLOTTO (Bovine Lacto Transfer Technique Optimizer) in reaction mixture. Genomic DNAs prepared by one-step extraction method from recalcitrant plant species such as Rubus coreanus, apple, grape and lettuce were successfully amplified by random primers in the reaction mixture containing 2 to 4% BLOTTO. Successful amplification of ${\gamma}$-TMT transgene in lettuce transformants by the specific primers was also achieved in the same condition, making rapid screening of positive transformants possible. Our results suggest that use of a simple DNA extraction procedure and incorporation of BLOTTO in reaction mixture in combination can reduce time and effort required for the analyses of a large number of germplasms and transformants by PCR-based techniques.
