Description
Technical field
The present invention relates to fungus conidium shape and pathogen-relatedprotein and encoding gene and application in microbiological genetic engineering and the plant protection field.
Background technology
(Magnaporthe grisea) is the fungi of Ascomycotina to Magnaporthe grisea, can infect paddy rice, wheat, barley, grain and other multiple grass, causes seasonal febrile diseases.Especially this bacterium is infected the rice blast that paddy rice causes all there is generation every year in each cultivated rice district in the world, harm extensively, serious.Generally speaking, the harm of rice blast can make paddy rice underproduction 5-10%, and the grave illness field can cause the paddy rice total crop failure.Rice blast was once repeatedly popular in China, also was one of main disease of China paddy rice.1993, rice blast was very popular in China, still underproduction over ten billion jin under the situation of control comprehensively.Magnaporthe grisea also can infect the turfgrass that Herba Stenotaphri helferi, Bermuda grass, eremochloa ophiuroides etc. belong to, and causes big area withered, is the common disease of turfgrass.
The conidium of Magnaporthe grisea resembles a pear in shape, and is made up of three cells.General 3 to 5 conidiums produce with the mode of the sympodium top from a conidiophore.After conidium discharges, on conidiophore, stay the scar of the shape of going down on one's knees.Magnaporthe grisea originates in conidial formation to infecting of plant, after its process comprises that conidium is attached on the plant leaf, through sprouting, appressorium forms with ripe, the generation and the accumulation of turgor pressure in the appressorium, infect nail and produce and directly the penetrating of plant epidermis, formation, the branch of infectivity mycelia in the vegetable cell, the infectivity mycelia is between vegetable cell and several steps such as expansion between tissue and field planting.When Magnaporthe grisea infects susceptible host, grey or the beige scab of infectivity mycelia more than the formation of the expansion between plant tissue diameter 2-3 millimeter, the mycelia of infecting in these scabs penetrates plant tissue and is differentiated to form conidiophore in the air, further forms conidium.Conidium descends to discharge, adheres to washing away of wind, rain, causes infecting again of plant.It is 3-5 days that Magnaporthe grisea is attached to the general required time of cycle that conidium produces again from conidium; At vegetative season, if condition is suitable, can repeatedly infect, work the mischief.Therefore, the conidium of Magnaporthe grisea is main primary source of infection and source of infection again, infects in the circulation indispensable in disease.The severity of rice blast and Magnaporthe grisea form that conidial what are directly related, so, the situation that people often measure the prediction disease to take place by conidium in the monitoring air.Research Magnaporthe grisea conidium forms and the molecular genetic of morphogenesis not only has important significance for theories for disclosing the pathogenic molecular mechanism of Magnaporthe grisea, and has significant application value for the control of instructing rice blast.
Report aspect formation of Magnaporthe grisea conidium and variation is fewer at present, even the general content that does not also all have about gene clone and molecule mechanism of report is arranged.
Hamer in 1989 etc. have reported Smo-mutant (Hamer, J.E., Valent, B., and Chumley, F.G., Mutations at the SMO genetic locus affect the shape of diversecell types in the rice blast fungus, Genetics, 1989 (122): 351-361.) be relevant Magnaporthe grisea conidium morphologic variation aspect report early.To be them at utilization Teflon film screen and obtain this mutant obtains in the process of defective Magnaporthe grisea mutant on appressorium forms, the mutant of this type can not form the conidium and the ascus of normal morphology, can form the thecaspore (can not sprout although the thecaspore of some Smo-is arranged) of normal morphology.The Smo-sudden change does not influence bacterial strain and nourishes and grows, forms conidium, reduction division and infecting host plant normally.
Shi in 1993 and Leung report that they handle the 70-15 bacterial strain with electroporation, from the bacterium that can survive, be separated to Con1-mutant (Shi, Z.X., and Leung, H.Genetic analysis and rapidmapping of a sporulation mutation in Magnaporthe grisea, MPMI, Vol.7, No.1,1993, pp.113-120.), it is different that this mutant and wild-type form conidial form, on each conidiophore, only produce a conidium of holding three cells of the elongation of giving birth to.Growth and the conidial formation of Con1-mutant on substratum has only 73% and 2.3% of wild-type respectively, can not form normal appressorium on slide glass or onion epidermis, and does not have pathogenic on original susceptible rice varieties.After 2 years, Shi and leung report that they use REMI to obtain a series ofly to form relevant mutant Con2--Con7-(Shi with conidium, Z.X., and Leung, H.Genetic analysis of sporulationin Magnaporthe grisea by chemical and insertional mutagenesis, MPMI, Vol.8, No.6,1995, pp.949-959.).CON1-7 (CON1 that comprises 1993 reports) is controlling a series of processes such as generation aerial hyphae, conidiophore, formation conidium, the normal conidium of formation form respectively.
Mutant con5-and con6-has completely lost conidium and has formed ability, and con1-, con2-, con4-and con7-act on the downstream influences of con5-and con6-and produce spore ability and conidial growth, and con4-and con7-sporulation quantity reduce about 35%.Con1-and con7-can not form appressorium, thereby have lost pathogenic to paddy rice, and con2-and con4-appressorium rate of formation obviously reduce, thereby pathogenicly obviously weaken.By the genetic affinity analysis revealed between them, Con1 and Con2 are chain, and Con5 and Con6 are chain, and have: the superordination of Con5>Con6>Con7 and Con2>Con1.
1998, they have obtained a kind of Magnaporthe grisea mutant that forms conidial deviant Forms by REMI reports such as Lau, they call ACR1-(Lau to it, G.W., and Hamer, J.E.Acropetal:Agenetic locus required for conidiophore architecture and pathogenicity inthe rice blast fungus, Fungal Genetics and Biology, 1998 (24): 228-239.).Magnaporthe grisea normally produces three to five conidiums from the top of a conidiophore, sympodium mode difference therewith, the conidium of ACR1-in the mode of bunchiness and is born on the conidiophore, these conidial apical cells can not produce top spore mucus (STM), therefore can not adhere to hydrophobic surface.The ability of the generation of conidium appressorium of ACR1-also reduces greatly, can sprout in the conidium that produces germ tube and have only 5% can form appressorium, so virulence also weakens greatly.Lau etc. have also cloned corresponding gene, and its open reading frame comprises 633 amino acid whose zones of transcribing of coding, and 3 ' end comprises the non-coding region of long about 1.3kb.Discover that this comprises 633 about 2kb of amino acid open reading frame, comprise the ORFs of a plurality of weak points, all lack homology with known protein in the present database.
More than the research report shows that it is a very complicated incident that conidial formation of Magnaporthe grisea and form thereof make up, and comprises many relevant with it gene.Clone these genes, separate bright their molecular function and the effect in conidial formation of Magnaporthe grisea and morphogenesis, thereby study their influences pathogenic to Magnaporthe grisea, to help to make clear the pathogenic molecular mechanism of Magnaporthe grisea, and might therefrom find can be used as albumen and the gene and the promotor of sterilant target, for the effective chemical control approach of exploitation rice blast and other plant seasonal febrile diseases is established the theory and technology basis.
