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

Injury caused by reactive oxygen species (ROS), known as oxidative stress, is one of the major damaging factors in plants exposed to environmental stress. Chloroplasts are specially sensitive to damage by ROS because electrons that escape from the photosynthetic electron transfer system are able to ...

  • 저자의 연구팀에서는 고구마 배양세포에서 산화 스트레스 유도성 POD (SWPA2) promoter를 개발하여 환경 스트레스 내성 식물체 개발에 활용하고 있다. 여기서 간단하게 SWPA2 promoter의 개발과정과 특성을 소개한다.
  • 따라서 환경 스트레스에 대한 식물의 적응능력을 이해하고, 환경 스트레스 조건에서도 식물의 생산성을 유지, 향상 시키는 일은 매우 중요하다. 여기에서는 각종 환경스트레스 를 받았을 때 생체에서 과다하게 발생되는 활성산소종 (reactive oxygen species, ROS)에 의해 생체가 받는 산화스트레스 (oxidative stress)와 이를 극복하는 식물의 항산화 기구 (antioxidative mechanism)에 대한 개론과 저자 연구팀이 개발한 산업적 가치가 높은 기반기술 (industrial platform technology)로 평가되는 산화스트레스 유도성 SWPA2 pro- moter를 이용하여 엽록체 항산화 기구 대사조절에 의한 복합스트레스 내성 농작물 개발에 대하여 기술한다.
