Background technology
Genetically modified organism is meant and utilizes biotechnology, foreign gene transferred in his species transforming its hereditary property, thereby obtained the proterties, nutritional quality of necessary for human and the biological new variety that produce.With genetically modified organism or with its food that is raw material processing comes is exactly genetically modified food.From 1994 first routine genetically modified food (transgenic Fructus Lycopersici esculenti) be born so far in the U.S., genetically modified organism has been widely used in field of food.
The Status of development of genetically modified organism
The research and development of international and domestic genetically modified organism, produce flourishly, cultivate the developing direction that new crop varieties is present crop breeding, improving crop yield, improve quality, improving aspects such as resistance and have great potential by the genetically engineered mode.Paddy rice (Oryza sativa L.) is the food crop of China's maximum, and sown area is about 3,100 ten thousand hectares throughout the year, and total yield accounts for 40% of China's total output of grain about 200,000,000 tons.Rice Production is occupied critical role in the agriculture production of China.
1991, usefulness particle gun transformation technologies such as Christou obtained transgenic rice plant, and coming years, gene gun technology are ripe day by day, and the report that all kinds of goal gene is imported paddy rice acquisition transfer-gen plant occurs in a large number.1994, Hiei etc. have set up agriculture bacillus mediated efficient japonica rice genetic conversion system, the agriculture bacillus mediated transformation system of java rice and long-grained nonglutinous rice is also successively set up, progressively reach the practical stage, become the mainstream technology of rice conversion, successively with the antiweed that do not have in the paddy gene storehouse, pest-resistant, disease-resistant, antiviral, salt tolerant, improve genes such as rice quality and introduce in the commercial rice varieties.China has also obtained important achievement in transgenic paddy rice cultivation aspect, import in multiple hybrid rice restorer line, the maintenance line with the cowpea trypsin inhibitor gene modified, Bt toxoprotein gene, Snowdrop lectin gene, antibacterial peptide gene with from the anti insect genes such as Xa21 gene of wild-rice, through the approval of the national Ministry of Agriculture, more than ten kind of transgenic paddy rice strain carried out environment release, interim test, wherein has 2 pest-resistant transgenic rices to obtain the genetically modified organism safety certificate.At present China is carrying out that environment discharges, the transgenosis of a plurality of pest-resistant transgenic rices of interim test contains the corn ubiquitin promoter in making up, so adopt ubiquitin promoter structure specificity method can specially detect pest-resistant transgenic rice delicately.
The management expectancy of genetically modified food
Genetically modified food is used widely, but transgenosis as a kind of new biotechnology, it is to the influence of human health, the eubiosis, the security of potential security genetically modified food potential more and more becomes human consumer's focus.
United Nations had passed through " Biosafety Protocol " in 2000, this protocol to except medicine all pass in and out active genetically modified organism about pass by, examine, detection, risk assessment and management, liability for damage etc. have made detailed regulation.Major country's legislation manages transgenic product in the world, the U.S., Canada, European Union, Japan, Korea S, Australia, Zelanian law are clearly stipulated, genetically modified organism needs with approval of authority, and through the Biosafety of strictness, environmental safety test just can field planting, environment discharges and as food, feed, European Union, Japan, Korea S, Australia, New Zealand etc. require genetically modified food to identify, and have stipulated the respective threshold level.China is in promulgation on May 23 calendar year 2001 " agriculture genetically modified organism security control regulations ", and regulation is carried out inspection and quarantine to agriculture genetically modified organism." the agriculture genetically modified organism identity management way " that came into effect on March 20th, 2002 also stipulated the sign system of genetically modified food.For the rules measure of carrying out above-mentioned United Nations and various countries, the detection of transgenic product is one of key measure, need determine genetically modified kind by qualitative detection, differentiate its whether be approved or got permission to be used for food and feed, any diffusion with the unknown transgenic product that prevents to have risk produces harm to society; Also need to determine by detection by quantitative the content of transgenic product, the clear and definite threshold level that whether has reached the country one belongs to's regulation is because the threshold level of each national transgenosis sign is all inequality.
Detection Method for Transgenic Food
Genetically modified food detects and is broadly divided into two classes, one class is a detection of nucleic acids, when foreign gene is inserted into recipient cell karyomit(e), generally to make up promotor, terminator, selectable marker gene and reporter gene, as cauliflower mosaic virus (CaMV) 35s promotor, nopaline synthase NOS terminator etc., the target of genetically modified food detection of nucleic acids is the foreign gene that inserts, the integration site that comprises foreign gene, promotor, terminator, the nucleotide sequence of selectable marker gene and reporter gene, present transgene component detect to have in the database and surpass 400 pairs of PCR detection primers and and the endogenous reference gene of kind more than 40.Another kind of is Protein Detection, promptly detects by protein or its function of inserting exogenous gene expression, and existing about 20 kinds of transgene protein detection methods have dropped into use in the transgenosis detection range.
Detection of nucleic acids is mainly used PCR method and biochip technology.PCR method has very high sensitivity, uses the most extensive in the transgenosis field.Have tissue specificity with protein and compare, round pcr is not subjected to the restriction of material.In addition, nucleic acid is than protein stabilization, and easy renaturation still can detect in processed food after the sex change.The key of PCR method is a design of primers, the general long 17-30nt that is of primer, the pairing of strict restriction upstream and downstream primer and primer self pairing.
Transgene protein detects euzymelinked immunosorbent assay (ELISA) (ELISA), immunochromatography (test strip method) and Western blotting etc.Although use the transgene protein detection method that some advantages are arranged, but many materials that are present in the food substrate, as tensio-active agent (Saponin/TSM), phenolic compound, lipid acid, endogenous phosphoric acid (ester) enzyme, all can suppress the special interaction of antigen one antibody, in addition, 3 grades or 4 level structures that immunodetection needs transgene protein to be kept perfectly, but the albumen of exogenous gene expression can be degraded in the course of processing, the detectivity of immunization method descends, thereby only is fit to unprocessed raw-material detection.In addition, some exogenous protein expression is specificity in a organized way, and for example some BT albumen major parts are expressed in the leaf in transgenic corns, and not in grain.These drawbacks limit the application of transgene protein detection method.
Genetically modified sign demand and some rules require transgene component in the food is carried out detection by quantitative to the restriction of gm content.
At present, rare both at home and abroad report can be quick, simple, special and be detected the method for the transgenic paddy rice and the goods thereof that contain the corn ubiquitin promoter delicately.
