Abstract:
This invention relates to a gene encoding chitinase (pCHI1, KFCC-10807) isolated from Xanthomonas sp. obtained from soil. Since this enzyme exhibited strong chitinase activity and antifungal activity against Candida sp., this can be used to protect plant pathogens which contain chitin as major cell wall component. This gene can be incorporated into plant chromosome by transforming with Agrobacterium tumefaciens to generate transgenic plants which are resistant against fungal infection.
Abstract:
The extraction method of edible oil (I) from plant Thalictrum Linne (II) consists of (1) crushing freeze-dried (II), and (2) extracting with chloroform and methanol. The edible seed oil is extracted by : freezing-drying Thalictrum Linne seed; pulverizing and utrasonicating to obtain the seed powder; extracting oil from the powder with chloroform and methanol; and purifying the extracted oil to obtain the final product. The seed oil has unsaturated fatty acid e.g. delta5-trans-linoleic acid.
Abstract:
PURPOSE: A vector for transforming Oryza sativa containing alpha-1,3-fucosyltransferase and/or beta-1,2-xylosyltransferase gene is provided to produce humanized glycoprotein. CONSTITUTION: A vector for transforming Oryza sativa contains a gene having a base of sequence numbers 1-3. The gene is inserted in forward and reverse directions. Bacteria are transformed with the vector. The bacteria are Agrobacterium. Oryza sativa transformed with the vector suppresses the expression of alpha-1,3-fucosyltransferase or beta-1-xylosyltransferase proteins. A method for producing humanized glycoprotein comprises: a step of introducing the vector to Oryza sativa cells and expressing glycoprotein the cells.

PURPOSE: A vector for transforming a plant, containing plasminogen activator (t-PA-prolaime) is provided to express plasminogen activator protein to active form. CONSTITUTION: A vector for transforming plant comprises: a seed-specific glutelin promoter sequence, rice plant-derived glutelin protein signal sequence and plasminogen activator gene(t-PA), synthetic plasminogen activator gene(st-PA), plasminogen activator gene(t-PAER), His6-tagged plasminogen activator gene(t-PAHis6) and prolaime-attahced plasminogen activator gene(t-PA-prolamine) in order. The glutelin protein signal sequence has a base sequence of sequence number 2. The vector produces transgenic rice plant which expresses plasminogen activator by introducing to plant cells.
Abstract:
PURPOSE: A novel cholera vaccine containing an E2 antigen gene or transgenic plant expressing the gene is provided to produce an antibody to the E2 antigen and prevent cattle sickness. CONSTITUTION: An E2 antigen gene of swine cholera protein contains ER-tagged sequence or ER-retention sequence. The E2 antigen gene contains a sequence of sequence number 1.
