연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Tall fescue is an open-pollinated, perennial, cool season grass species widely used for forage and turf. Tremendous progress has been made in genetic transformation of tall fescue in the past decade. Methods for generating transgenic tall fescue plants have been developed based on biolistic transfor...

문제 정의

  • 따라서 본 논문에서는 전 세계적으로 활발하게 추진되고 있는 대표적인 화본과 목초인 톨 페스큐의 국내외 연구 동향, 주요 연구결과 및 향후 전망에 대해 살펴보고자 한다.
  • 현재는 생명공학 기술의 발달로 인해 목초의 품질개선에 관한 새로운 육종 방법이 가능하게 되었다. 즉 조사료 품질에 있어서 가장 큰 제한인자인 낮은 소화율의 요인인 식물세포벽의 lignin 성분을 감소시키기 위하여 lignin 생합성에 관여하는 유전자의 발현을 down-regulation 시킴으로서 목초의 사료가치를 개선시키는 것이다. 이러한 접근법은 제지산업 분야에서 일찍이 펄프의 수율을 높이기 위해 사용되었었으며, 목본류에서는 상당한 성공사례가 보고된 바 있다.
