Abstract:
PURPOSE: A Sparus aurata-derived delta-6 desaturase protein, SaD6DES is provided to develop oil plants which produce functional gamma-linolenic acid and stearidonic acid. CONSTITUTION: A Sparus aurata-derived delta-6 desaturase protein has an amino acid of sequence number 2. A gene encoding the protein contains a base sequence of sequence number 1. A recombinant vector, pYES2-SaD6DES, contains the gene. A method for preparing gamma-linolenic acid or stearidonic acid in host cells comprises a step of transforming a host cell with the recombinant vector. The host cell is yeast. A composition for producing gamma-linolenic acid or stearidonic acid contains the gene.
Abstract:
A fusion protein of Escherichia coli enterotoxin protein and a neuraminidase epitope of Newcastle disease virus is provided to increase immunity against Newcastle disease virus in poultry, so that the protein is useful for prevention of Newcastle disease virus. A fusion protein of E. coli heat-labile enterotoxin subunit B and a neuraminidase epitope of Newcastle disease virus has the amino acid sequence of SEQ ID NO:1. A polynucleotide encoding the fusion protein has the nucleotide sequence of SEQ ID NO:2. An expression vector pLD-CtV-HN contains the polynucleotide of SEQ ID NO:2. A vaccine composition for preventing Newcastle disease virus contains the fusion protein as an effective ingredient. The immunity against Newcastle disease virus in poultry is increased by administering the fusion protein or a transgenic plant containing the expression vector pLD-CtV-HN into poultry.

Abstract:
The diagnostic method is disclosed which makes it possible to determine the presence of a virus infection in a crop by using the primer for nucleic acid amplification. The method provides the primer which can assay virus related diseases specifically, which is used to characteristic amplifying a specific DNA sequence. Included in the invention are the extraction of virus RNA from virus infected plant, the synthesis of cDNA of single strand from the virus RNA by means of reverse transcription reaction with using the primer, polymerase chain reaction(PCR) by using the primer for the template of the cDNA, and the certification of a virus specific DNA fragment band by agarose gel electrophoresis of the PCR product.
Abstract:
The present invention relates to a fatty acid chain elongase protein derived from Muraenesox cinereus, and to a method for producing an unsaturated fatty acid selected from a group consisting of a di-homo-gamma linolenic acid (DHLA), a docosatetraenoic acid (DTA), and a docosapentaenoic acid (DPA), using the same.
Abstract:
PURPOSE: A novel delta-6 desaturase gene derived from Muraenesox cinereus and a transformant containing the same are provided to obtain an oil seed which produces functional gamma-linolenic acid. CONSTITUTION: A gene encoding delta-6 desaturase derived from Muraenesox cinereus has a nucleic acid sequence of sequence number 1. A method for preparing a transformant comprises: a step of preparing an expression vector containing DNA sequence encoding delta-6 desaturase; a step of introducing the expression vector into a host cell; and a step of selecting a transfornmant containing the expression vector. The host cell is yeast(Saccharomyces cerevisiae). [Reference numerals] (AA) LA(substrate); (BB) GLA(product)
