摘要:
The present invention relates to a method for adjusting a sugar content, a starch content, or a shape of plant endosperm by using a sug-1 gene and a sug-2 gene, and a plant produced through the same. The inventors of the present invention have obtained a sugary-2 mutant generated by inhibiting the expression of a sug-1 gene and a sug-2 gene by treating N-methyl-N-nitrosourea (MNU) on a Hwacheong rice plant which is a rice plant japonica species, and have confirmed that the sugary-2 has an increased endosperm sugar content, a decreased starch content, and shows an intermediate shape of a sugary-1 mutant and a wild-type seed thickness compared to a wild-type Hwacheong rice plant. It can be considered that carbohydrate endosperm properties similar to a conventionally clarified sugary-1 mutant are ensured and morphological practicability is improved. Accordingly, the present invention can be useful for studies related to growth and quality of species related to plant endosperm. In particular, competitiveness of domestic rice is improved through enhanced quality and eating quality of rice species, so the rice industry is activated and a possibility of exporting best quality rice and seeds can be ensured.본 발명은 sug-1 유전자 및 sug-2 유전자를 이용한 식물체 배유의 당 함량, 전분 함량 또는 형태를 조절하는 방법 및 그에 따른 식물체에 관한 것으로, 본 발명자들은 MNU(N-methyl-N-nitrosourea)를 벼 자포니카 품종인 화청벼에 처리하여 sug-1 유전자 및 sug-2 유전자의 발현 저해로 발생한 sugary-2 돌연변이체를 얻었으며, 상기 sugary-2는 야생형인 화청벼에 비해 배유의 당 함량이 증가되고 전분 함량이 감소되며, sugary-1 돌연변이체와 야생형 종자 두께의 중간 형태를 보이는 것을 확인하였다. 이는 기존에 이미 밝혀진 sugary-1 돌연변이체와 비슷한 당질배유 특성을 가지면서도 형태적 실용성이 높아졌다고 볼 수 있다. 따라서, 본 발명은 식물체 배유 관련 품종 육성 및 품질 관련 연구에 유용하게 활용할 수 있으며, 특히 벼 품종의 향상된 품질 및 식미를 통해 우리 쌀의 경쟁력을 높임으로써 쌀 산업을 활성화하고 장차 최고 품질의 쌀 및 종자의 수출 가능성도 확보할 수 있다.
