摘要：
The present invention relates to a transgenic plant capable of regulating photosynthetic efficiency under light and low temperature stress, and to a regulation method using the same. According to the present invention, an Arabidopsis thaliana (L.) Heynh-derived FBN5 gene binds to a solanesyl diphosphate synthase which is involved in the synthesis of a tail structure on prenyl during a synthesis of plastochromanol-8 as a functional antioxidant molecule and plastoquinone-9 associated with photosynthetic efficiency, and regulates activities of the solanesyl diphosphate synthase, thereby regulating the production of plastoquinone-9 and plastochromanol-8. Thus, over-expression of the FBN5 gene in plants enables development of crops capable of maintaining photosynthetic efficiency in a normal level under low temperature stress.COPYRIGHT KIPO 2016본 발명에 따른 애기장대 유래 FBN5 유전자는 광합성 효율 관련 물질인 플라스토퀴논-9 및 항산화 기능성 물질인 플라스토크로마놀-8 합성 중 프레닐 꼬리 구조 합성에 관여하는 솔라네실이인산염 합성효소와 결합하여 이의 활성을 조절함으로써 플라스토퀴논-9 및 플라스토크로마놀-8의 생산을 조절하며, 이를 이용하여 식물체에 과발현시켜 저온 스트레스 하에서 광합성 효율을 정상으로 유지시키는 작물 개발에 활용할 수 있다.
