Abstract:
PURPOSE: A method for controlling nitrogen assimilation and disease tolerance using AtSIZ1 gene is provided to suppress the expression of the gene and to enhancing disease tolerance. CONSTITUTION: A method for controlling nitrogen assimilation in a plant comprises: a step of transforming a plant cell with a recombinant plant expression vector containing Arabidopsis thaliana-derived AtSIZ1 gene having a base of sequence number 1 to control AtSIZ1 expression; and a step of overexpressing AtSIZ1 genes. A plant with regulated nitrogen assimilation is prepared by transforming the gene with the recombinant expression vector. A composition for controlling nitrogen assimilation in a plant contains the AtSIZ1 gene.
Abstract:
본 발명은 벼 유래 종자 저장 단백질 안정성 조절 유전자 PDIL1 -1 및 이의 용도에 관한 것으로, PDIL1 -1 유전자가 결핍된 식물체에서 생산된 종자는 종자의 호분층의 두께, 종자 내 저장 단백질 및 유리당 (free sugar) 함량이 증가함에 따라 영양 성분 및 식미가 향상되므로 곡류, 두류 등 다양한 식량 작물에 적용하여 영양 성분 및 식미를 개선할 수 있으며, 병해충 저항성 단백질 및 산화 스트레스 저항성 단백질의 발현도 증가하므로 병해충 저항성 및 스트레스 저항성이 증대된 식물체를 제공할 수 있는 효과가 있다.

Abstract:
The present invention relates to a PDIL1-1 gene regulating stability of seed storage protein from rice and to use thereof. In the seed derived form a plant in which PDIL1-1 is inserted, nutrients and taste can be enhanced according to increase in thickness of aleurone layer of the seed, contents of a storage protein and a free sugar in the seed. Thus, the gene can be applied to various food crops such as cereals or soybeans, thereby improving nutrients and taste. Moreover, expression of a protein with pest resistance and oxidative-stress resistance is increased, thereby allowing a plant with improved pest resistance and stress resistance to be provided.
