Description

Bt PROTEIN C ry30Ga1, its encoding sox and application
Technical field
The present invention relates to biological technical field, be specifically related to a kind of new Bt albumen and encoding sox and application.
Background technology
In the human being's production process, insect pest is the important factor that causes agriculture prodn loss and influence human health, adds up according to FAO, and the financial loss that whole world agriculture prodn every year causes because of insect pest is up to 14%, and disease is with a toll of 12%, and crop smothering is with a toll of 11%.The amount of loss is equivalent to the half the of the Chinese agriculture gross output value, more than 4 times of Britain up to 1,260 hundred million dollars.In addition, mosquito matchmaker disease is occupied critical positions in preventive medicine, wherein the sick transmissibility of mosquito such as singapore hemorrhagic fever and yellow jack matchmaker strong, popular wide, sickness rate is high, hazardness is big.According to the WHO statistics, the annual singapore hemorrhagic fever number that infects in the whole world reached 8,000 ten thousand, and Hainan Province of China once broke out twice singapore hemorrhagic fever in 1980 and 1986, and morbidity reaches 437469 example and 113589 examples respectively.Singapore hemorrhagic fever and yellow jack are mainly propagated by Aedes aegypti.
In order to reduce these losses, for many years, generally adopt the chemical prevention means to prevent and treat to crop pests and mosquito; But because the long-term, a large amount of of chemical pesticide use; Caused the pollution to environment, pesticide residue increases in the agricultural byproducts, has brought harm for human existence and health.In addition, chemical pesticide has has also killed and wounded natural enemy and other useful thing in kill pests, destroyed the eubiosis.Compare safe, effective, persistent characteristics that biological control has with chemical prevention.And a series of problems of having avoided chemical prevention to bring.Therefore, biological control technology has become the focus of people's researchs.In biotic pesticide, bacillus thuringiensis is present the widest, the maximum quasi-microorganism sterilant of output of purposes in the world.
Bacillus thuringiensis (Bacillus thuringiensis is called for short Bt) is a kind of gram positive bacterium, and its distribution is very extensive;, gemma can form the parasporal crystal of forming by protein when forming with insecticidal activity; Have another name called insecticidal crystal protein (Insectididal crystalproteins is called for short ICPs), ICPs is by the cry genes encoding; Sensitive insect there is strong toxicity, and to higher animal and people's nontoxicity.In recent decades, Bt has been widely used in controlling insects such as multiple lepidopteran, Diptera, Coleoptera.In addition, Bt also has the effect of control evil to various pests such as Hymenoptera, Homoptera, Orthoptera, Mallophaga and plant pathogeny line insect, mite class, protozoon.At present Bt has become the strong substitute of chemical synthetic pesticide in the control of agricultural pests, injurious forest-insect and sanitary insect pest, and Bt still be that transgenic pest-resistant engineered plant important function of gene is originated.
(Adang M.J et al from Schnepf in 1981 has cloned first gene that can express insecticidal activity from strain HD-1Dipel since; Characterized full-length andtruncated plasmid clones of the crystal protein of Bacillus thuringiensissubsp.kurstaki HD-73 and their toxicity to Manduca sexta; Gene; 1985,36 (3): 289~300.), people separating clone the gene of more than 390 kind of coded insect-killing crystallin; They are confirmed as different crowd, subgroup, class and subclass (Crickmore N respectively according to the amino acid sequence coded homology; Zeigler D R, Feitelson J, et al.Revision of the nomenclature for the Bacillus thuringiensis pesticidalcrystal proteins.Microbiol Mol Biol Rev; 1998,62:807-813; Http:// www.biols.susx.ac.uk/Home/Neil_Crickmore/Bt/).Generally speaking, Cry1, toxalbumin such as Cry2 and Cry9 are effective to lepidoptera pest; Wherein the maximum of research are Cry1 and Cry9 proteinoid, and the insecticidal crystal protein molecular weight that their are encoded is 130-140kD, and many genes have been widely used in the control (Kozie of the lepidoptera pest of plant at present; M.G.; Beland, G.L., Bowman; C.; Et al.Field performance of elite transgenicmaize plants expressing an insecticidal protein derived from Bacillusthuringiensis.Bio/Technology, 1993,11:194-200; Perlak, F.J., Deaton, R.W., Armstrong, T.A., et al.Insect resistant cotton plants.bio/technology, 1990; 8:939-943; Van Frankenhuyzen; K., Gringorten, L.; And Gauhier; D.1997.Cry9Cal toxin, a Bacillus thuringiensis insecticidal crystalprotein with high activity against the spruce bud worm (Choristoneurafnniferana) .Appl.Environ, Microbviol.63:4132-4134; Wang Fei, 2001, the research of bacillus thuringiensis specific strain biological characteristics and the new gene of cry9, Master's thesis, Nankai University).Tribactur Israel subclass (B.thuringiensis subsp.israelensis; Abbreviation Bti) toxin protein that produces has fine insecticidal activity to mosquito, is extensively applied to control (Goldberg L J, the and Margalit J of mosquito; 1977.A bacterialspore demonstrating rapid larvicidal activity against Anopheles sergentii; Uranotaenia unguiculata, Culex univitattus, Aedes aegypti; And Culexpipiens.Mosqito News, 37:355-358; ).Simultaneously; Cyt albumen has cytolytic, and some Cry albumen is had synergism and delays resistance (Wu, the D. of insect; Johnson; J.J., and Federici, B.A.1994.Synergism of mosquitocidal toxicity betweenCytA and CryIVD Proteins using inclusion sproduced from clonedgenes of Bacillus thuringiensis.Mol.Microbiol.13:965-972; Wirth; M.C.; Georghiou, G.P., and Federeci; B.A.1997.CytA enables CryIVendotoxins of Bacillus thuringiensis to overcome high levels of CryIVresistance in the mosquito, Culex quinquefasciatus.Proc.Natl.Acad.Sci.94:10536-10540)
Find the history in existing so far more than 100 year of Tribactur from the beginning of this century, aspect the preventing and treating of farm crop and gardening plant insect, injurious forest-insect and sanitary insect pest, be widely used, also play good effect.But owing to use Tribactur on a large scale and repeatedly, many insect populations are producing resistance to insecticidal crystal protein in succession in varying degrees.The history in existing more than 50 year of the Utilization of pesticides that is the basis with the Bt insecticidal crystal protein; The initial resistance of insect that never detect to Bt; But; Begin mid-term 80 year last century; Resistance problem constantly is confirmed in laboratory and field test (M cGaughey, W.H.1985.Insect resistance to the biological insecticide Bacillus thuringiensis.Science.229:193-195), and reason mainly is continue to use single variety and inferiorly cause the Bt of dosage and the application of Bt transgenic anti-insect plants causes insect population to receive the selective pressure of sterilant for a long time.1985, McGaughey report warehouse grain pest Indian meal moth (Plodia interpunctella) under the selective pressure of Dipel (the commodity preparation of Bt subsp.kurstaik HD-1), bred for 15 generations after, resistance increases by 97 times; Under the high dosage selective pressure, resistance can increase by 250 times.Nineteen ninety, confirm first that in Hawaii big Tanaka's small cabbage moth has produced tangible resistance (Tabashnik, B.E. to the Bt sterilant; Finson; N., Groeters, F.R.; Et al.1994.Reversal of resistance to Bacillus thuringiensisin Plutella xylostella.Proc.Natl.Acad.Sci.USA.91:4120-4124); Since the nineties in last century,, found that the Bt sterilant obviously descends to the small cabbage moth control effect on China Application of B t sterilant time long Shenzhen and Guangzhou, Shanghai and other places; Mean resistance form (Feng Xia .1996. Guangdong small cabbage moth is to the resistance research of Bacillus thuringiensis. insect journal, 39 (3): 238-244; Hofte, H., Van Rie, J.; Jansens, S., Van Houtven; A., Vanderbruggen, H.; And Vaeck, M., 1988.Monoclonal antibody analysis and insecticidal spectrum ofthree types of lepidopteran-specific insecticidal crystal proteins ofBacillus thuringiensis.Appl.Environ.Microbiol.54:2010-2017).Find at present in the laboratory and the field has at least tens kinds of insects that Bt and insecticidal crystal protein thereof have been produced resistance, arrive with the selective pressure mathematical model prediction, under the condition of Bt transgenic anti-insect plants selective pressure; Insect will produce resistance (Schnepf, E., Crickmore; N.; Van Pie, J., et al.1998.Bacillus thuringiensis and its pesticidal Crystalproteins.Microbiol.Mol.Biol.Rev.65 (3): 775-806).In addition; There are some researches prove that Bti does not find resistance problem (Regis L.et al. as yet in the use in land for growing field crops; 2000.The useof bacterial larvicides in mosquito and black fly control programsinBrazil.Mem.Instituto Oswaldo Cruz; 95:207-210.); But mosquito constantly is confirmed in the laboratory to its resistance problem; This situation also may (Georghiou G P occur big Tanaka; And Wirth M C, 1997.Influence of exposure to singleversus multiple toxins of Bacillus thuringiensis subsp.israelensis ondevelopment of resistance in the mosquito Culex quinquefasciatus (Diptera:Culicidae) .Applied and Environmental Microbiology, 63:1095-1101.).
