摘要：
PURPOSE: A stress adaptation of an Oryza sativa plant by OsSIZ1 and OsSIZ2 expression is provided to express the proteins in the plant and to ensure stress tolerance. CONSTITUTION: An OsSIZ1 protein derived from an Oryza sativa plant contains an amino acid sequence of sequence number 1. The OsSIZ1 protein comprises: an SAP domain(12-45 amino acid residue) which is associated to DNA bond； a plant homeodomain-finger(PHD)(116-167th amino acid residue) existing in a plant Siz/PIAS protein； a PINIT domain(274-277th amino acid residue) which is essential for nucleus preservation； an SIZ/PIAS-RING (SP-RING) domain(360-412th amino acid residue) which is needed for SUMO E3-ligase activity； and a SX motif(606-608th amino acid residue) for enhancing SUMO binding.본 발명은 OsSIZ1 및 OsSIZ2 단백질 발현을 통한 벼 식물의 스트레스 적응 방법에 관한 것이다. 더욱 상세하게는 벼 식물체 내에서 고온, 저온, NaCl 및 ABA와 같은 환경적 스트레스에 적응하기 위하여 수모 접합(Sumoylation)에 관련된 단백질 OsSIZ1 및 OsSIZ2 발현을 통한 스트레스 적응방법에 관한 것이다.
