Background technology:
Insect pest is an important factor that causes the agriculture production loss.According to statistics, the direct economic loss that causes to agriculture production in insect pest every year is up to 13%.
Chemical insecticide once to pest control, stablize agriculture production and made significant contribution.Along with people to the understanding of chemical insecticide environmental hazard, the reinforcement day by day of environmental consciousness, environmentally safe biotic pesticide have become the focus of research.In biotic pesticide, what research at present was the clearest, application is the most successful is a class Bt preparation.The effective constituent of Bt preparation is Bt insecticidal crystal protein (ICP).Bt insecticidal crystal protein (ICP) is that bacillus thuringiensis produces in the gemma forming process.But find also in the production that the Bt preparation exists problem of unstable, easily run off in the field on the one hand that drug effect is short by rain drop erosion; On the other hand, because the active ingredient of Bt sterilant is a protein, under the irradiation of sunlight middle-ultraviolet lamp, easily is decomposed and lost efficacy.The success of plant transgene provides a brand-new route for the application of Bt insecticidal crystal protein.
Bt insecticidal crystal protein (ICP) is to be produced by the Bt genes encoding.There is homology in various degree in the aminoacid sequence of many ICP.1989, (53:241-255) about 42 genes that will find at that time according to the homology of the insecticidal spectrum of ICP and aminoacid sequence were divided into five big classes, 15 subclass for H fte H and Whiteley HR, Microbio.Rev. for H fte and Whiteley.The gene family (Cry) that wherein preceding four classes are crystallin, the 5th class is called as cytolysis protein gene (Cyt).The CryI genes encoding is to the virose CryI albumen of lepidopterous insects, the CryII genes encoding is to lepidopteran and the virose CryII albumen of dipteral insect, the CryIII genes encoding is to the virose CryIII albumen of coleopteron, and the CryIV genes encoding is to the virose CryIV albumen of dipteral insect.Because the continuous isolation identification of new killing gene, two-fold-classification method according to H fte and Whiteley, 1992, (Feitelson et al. such as Feitelson, Bio/Technology, 10:271-275,1992) original classification is replenished, the Bt gene is divided into 7 big classes, 29 subclass.Remove 5 original big classes, increased CryV and CryVI two big classes newly.Along with the continuous increase of new Bt gene dosage, it is found that original sorting technique exists amino acid identity and the conflicting problem of desinsection specificity.Therefore, do not have spondylopathy Neo-Confucianism in nineteen ninety-five and can set up the Bt unnamed gene council that forms by people such as Crickmore specially in the annual meeting, proposed with the insecticidal proteins amino acid sequence homology is the classification naming system of sole criterion, the Bt gene is divided into 17 big classes, 3 subclass (Crickmore et al, 1995), augmenting in 1996 is 21 big classes, 44 subclass; To on August 2nd, 2002, the Bt gene reached 42 big classes, 110 subclass, amounts to more than 200 Bt gene order.
Typical ICP is made up of two portions, the structure fragment of the active fragments of N end and C end, and the ICP that has structure fragment is called as parent toxin.It produces activated toxicity peptide through after the digestion of proteolytic enzyme.The someone points out recently, and the active fragments of holding at N is divided into toxicity district and cell land again.After the Bt insecticidal crystal protein is by the target insect's food-taking, produce the active toxin molecule through dissolving and two steps of enzymolysis, the active toxin that discharges can pass the direct and gastrointestinal epithelial cells effect in trophocyte space, insect midgut road.The cell land is with after the receptor-specific of insect midgut tract epithelial cell combines, and the toxicity district directly acts on cytolemma, makes membrane perforation, destroys the osmotic equilibrium of cell, causes the cracking of cell at last.
1987, (Vaeck et al. such as Vaeck, Nature, 328:33-37,1987), (Barton etal., Plant Physiol.85:1103-1109 such as Barton, 1987), (fischoff et al. such as Fischoff, Bio/Technology, 5:807-813,1987) obtained the trans Bt gene plant.But the insect-resistance of these early stage trans Bt gene plant that they obtain is all very weak, is difficult to detect transcribing of mRNA, and the protein expression amount is very low.Cause the low reason of Bt gene expression amount in plant to have many: for example, 1, be rich in the AT sequence, the mRNA instability of in plant, expressing in the wild Bt gene; Intron cleavage site, the transcription termination signal sequence that 2, may have eukaryotic gene in the wild Bt gene cause the abnormal processing of the imperfect or transcript of transcript; 3, microorganism and plant have very big-difference on the frequency of utilization to codon in translation, and translation efficiency is reduced; 4,5 ' of eukaryotic gene-UTR sequence and prokaryotic gene are very different, and 3 ' end of eukaryotic gene needs tailing recognition signal sequence.Therefore, make the Bt gene in transgenic plant, efficiently express, must effectively transform wild Bt gene.
Nineteen ninety, (Adang et al such as Adang, EP0359472,1990) by the A+T content of adjustment wild gene and the frequency of utilization of codon, itself and dicotyledon gene are consistent, having removed influences the AATGAA that gene is expressed in plant, synthesized a new Btt gene: the homology of new gene and protogene is 85%, and A+T content drops to the level (55%) of normal plants gene.Utilize the gene-transformed plant of transforming, the proteic expression amount of Bt is improved.
1991, (Perlak et al such as Perlak, PNAS USA, 7164 88:3324-3328 1991) under the situation that does not change the crystallin aminoacid sequence, the Cry1Ab gene has been carried out partly transforming or transforming fully by synthetic, selected the codon of plant-preference for use, part has been removed the element of interference base because of expressing in the former sequence in plant, as the ATTTA sequence, PM and FM gene have been obtained; As a result, the target protein expression amount acquisition of changeing PM and FM gene plant improves.
1992, people such as Guo's three heaps (Guo's three heaps etc., Chinese invention patent application number: 95119563.8) by the double chain synthesising DNA method, synthetic the GFM killing gene that merges of the Cry1Ab of total length 1824bp and Cry1Ac, the expression amount of Bt toxalbumin in plant increases substantially as a result, and complete synthesis gene has improved about 100 times than the expression amount of protogene.Afterwards, many scientific workers have carried out a large amount of transformation research to the Bt killing gene, and utilize the Bt killing gene of transforming to do a large amount of Plant Transformation work, lay the foundation for cultivating the Bt zoophobous.According to incompletely statistics, Bt gene (the being used for transgenic plant) patent 40 of existing so far part improvement or synthetic is multinomial.
The about 130kD of coded insect-killing crystallin of typical C ryI gene, and at present reforming composite most of CryI genes remove for part coded insect-killing crystallin C end dna sequence dna prescind gene.Three examples more than enumerating are the genetic modification of prescinding encoding sequence.To the transformation Cry1 Gene Sequence Analysis delivered as can be seen, keep the needs that the proteic dna sequence dna of original gene 5 ' the end about 70kB of coding just can satisfy plant transgene.
