Abstract:
The present invention relates to fermented balloon flower root pills and a preparation method thereof and, more particularly, to fermented balloon flower root pills obtained by mixing medicinal herbs to a fermented balloon flower root extract to make a concentrate, and to a preparation method thereof. According to the present invention, provided are fermented balloon flower root pills having medicinal effects on the improvement of phlegm discharge function and the promotion of brain activity by mixing medicinal herbs to a fermented balloon flower root extract to make a concentrate, and to a preparation method thereof. Therefore, the fermented balloon flower root extract and various medicinal herbs having medicinal effects can be prepared in a pill formation which has the advantages of being easy to carry and having constant doses unlike a powder formulation.
Abstract:
PURPOSE: A transformant having high content of methionine using perilla-derived seed storage protein is provided to specifically overexpress PrLeg in potato tuber and produce crops having rich necessary amino acid content. CONSTITUTION: An expression vector contains a gene of perilla-derived seed storage protein. A promoter of a gene for tuber-specific expression is Patatin promoter derived from potato. The gene of seed storage protein is nucleic acid encoding PrLeg protein. The expression vector is CaMV35S::PrLeg/pSJ001, or Patatin::PrLeg/pSJpatatin01. A method for preparing a transformant having high content of methionine comprises: a step of preparing the expression vector; a step of transforming plant tissue with the expression vector; and a step of selecting transformant in which the expression vector is introduced.

Abstract:
Provided is a method for preparing a transformed potato which includes the increased contents of vitamin C in a tuber and a leaf, and improve resistivity to external stress so that the transformed potato grows up well. A transformed potato is transformed to a dihydroascorbate reductase gene derived from a hairy root of sesame. The increased amount of dihydroascorbate reductase gene is expressed in a leaf of the potato when compared with a wild potato under promoter control of a gene for general expression. The promoter of the gene for general expression is a CaMV35S promoter. The increased amount of dihydroascorbate reductase gene is expressed in a tuber of the potato when compared with the wild potato under promoter control of a gene for tuber specific expression. The promoter of the gene for tuber specific expression is a promoter of a patatin gene.
Abstract:
The present invention relates to a method for increasing the transformation efficiency when a transformed plant with foreign genes introduced by redifferentiating potato plants in vitro or by using agrobacteria is developed. The manufacturing method of transformed potato plants of the present invention uses pieces collected from the plant grown from a novel shoot emerged from a micro tuber of a potato or the plant subcultured twice or less in the process of performing transformation, co-cultivates agrobacteria including recombination carriers and plant tissue pieces, and uses glucose instead of sucrose, which has been used previously, as a carbon source in a shoot medium, thereby increasing the redifferentiation rate of potato plants and having the effect of transforming 10% or more of the redifferentiated plants even from the potato cultivars having a very low transformation efficiency. Accordingly, if the method of the present invention is applied to the transformation of potatoes, a plant transformation system with a higher efficiency than the conventional method can be established. Furthermore, the present invention has a relatively low transformation efficiency according to some cultivars or systems, and can be usefully used in developing and commercializing genetically modified potatoes with a specific gene introduced.
