Abstract:
본 발명은 SOD2 및 NDPK2 유전자가 각각 도입된 후 세대진전을 통해 유전자가 안정적으로 고정된 형질전환 식물체간의 교배를 통하여 위 두 종류의 유전자가 복합 도입되도록 한 후 유전자집적에 의하여 고농도의 아황산가스에도 저항성을 보이는 페튜니아(종자)에 관한 것이다.
Abstract:
PURPOSE: A method for producing a large amount of transgenic plants using somatic cell embryo of Sweet Yellow is provided. CONSTITUTION: A method for producing a large amount of transgenic plants using rose 'Sweet Yellow' somatic cell embryo and embryogenic callus comprises: a step of co-culturing somatic cell embryo GUS gene-transformed Agrobacterium tumefaciens and GFP gene-transformed Agrobacterium tumefaciens; a step of culturing the co-cultured somatic cell embryo or embryogenic callues in an embryo selection medium containing 250mg/L^-1 of cefotaxim; a step of culturing the somatic cell embryo or embryogenic callus in a medium containing cefotaxim solely or together with PPT(phosphinothricin); a step of culturing a cultured shoot in a medium; a step of culturing the shoot in a shoot growth medium; a step of culturing 1-1.5cm of shoots in a multi-shoot growth medium; and a step of culturing the multi-shoots in a root inducing medium.
Abstract:
PURPOSE: A Petunia transformant containing SOD gene and NDPK2 gene is provided to ensure resistance to air pollution, especially sulphur dioxide. CONSTITUTION: A method for preparing a Petunia transformant with resistance to air pollution comprises: a step of introducing SOD gene to Petunia and preparing transformed Petunia in which a gene is stably immobilized through generation advancement; a step of introducing NDPK2 gene to Petunia and preparing transformed Petunia in which a gene is stably immobilized through generation advancement; a step of crossbreeding the transformants to introduce SOD gene and NDPK2 gene; a step of selecting a transformant containing SOD gene and NDPK2 gene with resistance to sulphur dioxide; and a step of self-pollination of the transformant and secondarily selecting a sulphur dioxide with resistance to sulphur dioxide. [Reference numerals] (A) Treat with 60ppm of sulfurous acid gas for 8 hours; (AA,CC) 2 days after treatment; (B) Treat with 60ppm of sulfurous acid gas for 4 hours; (BB,DD) 7 days after treatment
Abstract:
The present invention relates to a transgenic petunia line (seed) having an improved ability to remove indoor air pollutants, and more specifically, prepares a petunia transformant having an improved ability to remove indoor air pollutants by introducing a formaldehyde dehydrogenase gene derived from Arabidopsis thaliana into a petunia line.
