Abstract

In this study, Agrobacterium-mediated transformation was tested to the mycelium culture of Flamulina velutipes which is very popular as an edible mushroom in Korea. Particularly, aluminum oxide particles were used to generate wounds in F. velutipes mycelia via vigorous shaking prior to agro-infiltration. The result showed that transformants resistant to hygromycin could be obtained only from the mycelia with physical wounds. Gene transfer was verified by genomic DNA PCR. This study suggested a convenient tool to improve Agrobacterium-mediated transformation of F. velutipes.

본 연구에서는 국내에서 식용으로 재배되고 있는 팽이버섯의 균사체에 대하여 Agrobacterium을 이용한 형질전환을 시도하였다. 특히 물리적 연마제인 미세 aluminum oxide 입자를 팽이 균사체와 함께 강하게 교반함으로써 물리적 상해를 지니는 균사체를 제조하였으며 감압침윤에 의한 Agrobacterium 이용 형질전환을 시도하였다. Hygromycin 저항성을 이용한 선발 결과, 대조군에서는 균사체 생육이 전혀 관찰되지 않은 반면 물리적 상해군에서는 형질전환균사체 생육이 확인되었다. Genomic DNA PCR에 의한 유전자 도입을 확인함으로써 팽이균사체에 대한 매우 간편한 형질전환법을 제시할 수 있었다.
