Description
Technical field
The present invention relates to a kind of method and special-purpose gene thereof of cultivating anti-disease wheat.
Background technology
Antibacterial peptide is that a class extensively is present in insect, the intravital small molecule active antimicrobial polypeptide of animal and plant.Its molecular weight is little, Heat stability is good, have resistance of wide spectrum (in strong, Qiu Fangping opens the tinkling of pieces of jade. antibacterial peptide and application prospect thereof. Changchun Polytechnic Univ.'s journal [J], 2004,25 (1): 65-67).Since Sweden scientist Boman in 1975 is separated to antibacterial peptide cecropin cecropin (BomanHG from the sky silkworm chrysalis, Hultmark D.Cell-free immurityin insects[J] .Ann Rev Microbiol, 1987,41 (2): 103-107), a large amount of antibacterial peptides are found gradually, are separated and utilized.Antibacterial peptide is divided into 4 classes substantially: cecropin (Cecropin), Magainin (Magainin), melittin (Melitiny) and plant protecting chemical (Defensin).Plant protecting chemical (Defensin) be plant in the long-term evolution process for resisting one natural cover for defense that biological adverse circumstance prestores.Up to now, 4 kinds of antibacterial peptide Rs-AFP from radish seed and blade, have been separated to, they are the plant protecting chemical that is rich in Gelucystine, at the external anti-microbial activity that all shows in various degree, wherein Rs-AFP1, Rs-AFP2 are for resisting fungal infection (the Terras FRG that plays an important role in the radish seed germination process, Eggermont K, Kovaleva V, et al.Small cysteine-richantifungal proteins from radish:their role in host defense[J] .PlantCell, 1995,7:573-588).Experiment in vitro shows, Rs-AFP1, Rs-AFP2 are inhibited to multiple thread pathogenic fungi growth, and particularly Rs-AFP2 is stronger at external fungistatic effect, mycelial growth (IC that can strongly inhibited fusarium graminearum (Fusarium graminearum)
50=1-3 μ g/ml), the mycelial growth to pink colour bread mould (Neurospora crassa) also has higher inhibition activity (IC
50=1 μ g/ml), also wheat class De Shi mould (Pyrenophora tritici-repentis), Rice Blast Fungus (Pyricularia oryzae) etc. had resistance of wide spectrum (Spelbrink RG, Dilmac N, Allen A, et al.Differentialantifungal and Calcium Channel-Blocking activity among structurally relatedplant defensins[J] .Plant Physiology, 2004,8 (135): 2055-1067).Human agrobacterium-mediated transformations such as Zhi Daying changed the Rs-AFP1 gene in the wheat in 2004, the preliminary observation transgenic line shows the Powdery Mildew delayed onset or morbidity obviously alleviates (Zhi Daying than contrast, Xu Chunhui, Xue Zheyong, Deng. agriculture bacillus mediated AFP1 gene transformation wheat obtains transfer-gen plant [J]. Shandong agricultural sciences, 2004 (3): 14-16).Sophisticated Rs-AFP1 is identical with the proteic aminoacid sequence of Rs-AFP2 other amino acid except that the 5th and the 27th, the 5th amino acids is Glu among the Rs-AFP1, and Rs-AFP2 the 5th amino acids is Gln, Rs-AFP1 the 27th amino acids is Asn, and Rs-AFP2 the 27th amino acids is Arg, and Rs-AFP2 has higher positive charge, demonstrates higher anti-mycotic activity, particularly this phenomenon is particularly remarkable in the high ionic strength substratum, and the biological activity of Rs-AFP2 is subjected to Ca
