Specific embodiment
The acquisition of embodiment 1:GeCPR full-length gene
P450 gene is filtered out from transcript profile data with 5 ' end leading portion gene orders, passes through nested PCR amplification gene
Sequence:
The nest-type PRC first step, designs two upstream primers and universal primer, primer are synthesized by the Shanghai section of holding up.
First stage: upstream primer GeCPRF-1 (5 '-AGCAACAAAGGAATATGTGC-3 ') downstream primer UN36 (5 '-
GACTCGAGTCGACATC GATTTTTTTTTTTTTTTTTT-3 ') carry out gene magnification；
Second stage: it uses the first stage obtains after 10 times of product dilution, upstream primer GeCPRF-2 (5 '-
GGAGAGTCTGGTGAAGAAC-3 ') downstream primer UN36 (5 '-GACTCGAGTCGACATC GATTTTTTTTTTTTTTTTTT-
3 ') obtained target gene is detected and is spliced, online software detection http is carried out to the P450 gene that splicing obtains: //
Linuxl.soflberry.com/berry.phtml predicts the possible initiation codon of P450 and terminator codon, design primer
It is expanded, upstream primer: GeCPR-F (ggatccATGCAATCAGAGGCGATG) downstream primer: GeCPR-R
(ctcgaaTCACCAGACATCTCTCAG), product is recycled, carries out TA clone, picking positive colony is sequenced, is obtained
To correct full-length gene.
The building of embodiment 2:GeCPR carrier for expression of eukaryon
The GeCPR full-length gene target fragment of recycling is connected with 18T carrier, is transformed into bacillus coli DH 5 alpha, is obtained
Escherichia coli with PMD18T-GeCPR carrier；
The strain Escherichia coli activation of correct PMD18T-GeCPR carrier will be sequenced, picking single bacterium falls within Amp resistance LB
37 DEG C of culture 12h in fluid nutrient medium, while by PENTRTM- 2B is activated in the culture medium kind containing Kan antibiotic, is used
The plasmid extraction kit bought in the raw work in Shanghai extracts PMD18T-GeCPR and PENTRTM- 2B plasmid, while using I He of BamH
Xho I is respectively to plasmid pMD18T-GeCPR and pENTRTM- 2B carrier synchronizes double digestion, and the digestion system used is as follows: matter
Grain 6 μ L, BamH I 1 μ L, Xho I 1 μ L, 10 × Buffer 2 μ L, ddH210 μ L of O), purpose is recycled using plastic recovery kit
Target fragment after recycling is attached by genetic fragment, converts the Yu Hanyou Kan antibiotic into DH5 α competent cell
Plate on 37 DEG C of culture 12h, picking single colonie, which is transferred in Kan resistance LB culture medium, cultivates 12h, extract plasmid carry out double digestion
Detection, detects correct entry clones carrier pENTRTM2B-GeCPR carries out LR with purpose carrier pH2GW7.0 and reacts, and converts DH5
α, is transferred to 37 DEG C of culture 12h on the plate containing Spe (50 μ g/mL) antibiotic, the bacterium colony that the single bacterium of picking is formed be transferred to containing
It is cultivated in the LB liquid medium of identical antibiotic, plasmid extracts, and synchronizes double digestion detection to the plasmid of acquisition,
Obtain pH2-35S-GeCPR carrier.
It will be screened on all carriers built all culture mediums containing antibiotic, and extract plasmid, pass through confrontation
Grain synchronizes double digestion and PCR verifying, detects the correctness of recombinant plasmid, and carry out PCR and detect these the result shows that pH2-
35S-GeCPR vector construction success (as shown in Figure 2).
Embodiment 3: conversion halimasch
PH2-35S-GeCPR carrier is transferred in Agrobacterium competence pMP90 using electrotransformation, is containing Spe antibiosis
It is coated on the plate of element, is inverted 37 DEG C, 12h of culture, picking single colonie is carried out Liquid Culture, carried out using specific primer
Bacterium solution PCR spreads cultivation bacterium solution after detection is correct, transfects halimasch using the method that Agrobacterium infects halimasch.After transfection
Halimasch is applied in the PDA culture medium containing Hyg (100mg/L), and 26 DEG C of culture 26d pickings grow intact mycelia and train in liquid
It supports and is cultivated in base 2 weeks, the halimasch of successful conversion is not free of hygromycin gene, can not contain Hyg (100mg/L)
Normal growth on culture medium.
Using common wild type halimasch and transgenosis halimasch as template, drawn with the specificity of designed GeCPR gene
Object carries out PCR amplification, and whether verifying foreign gene is inserted into.As a result as shown in figure 3, the result of PCR: WT (wild type halimasch) is no
The foreign gene of 2094bp segment can be amplified, and transgenic strain can amplify target fragment, it was demonstrated that the success of GeCPR gene
It is transferred in halimasch.
Embodiment 4: the transformation efficiency of transgenosis halimasch 4- salicylic alcohol
By HPLC high performance liquid chromatography, the effective medicinal ingredient Gastrodin precursor substance tetrahydroxy benzene methanol of halimasch is detected
Transformation efficiency, 2,4,6,8,10, the tetrahydroxy benzene methanol concentration that generates afterwards for 24 hours are specifically detected, as a result as shown in figure 4,4-
The yield of 4- salicylic alcohol is basically unchanged between 10h, is increased again after catalysis for 24 hours.
The present invention obtains cytochrome P450 reductase (GeCPR) gene in Rhizoma Gastrodiae by clone, by constructing GeCPR base
Halimasch is transfected because of carrier for expression of eukaryon, then through mediated by agriculture bacillus, screening obtains the transgenosis halimasch bacterial strain of positive colony, energy
Success converts 4- cresols to the precursor substance 4- salicylic alcohol of Gastrodin, not only contributes to the yield for improving Gastrodin, also
Environmental pollution can be reduced.
Finally, it is stated that preferred embodiment above is only used to illustrate the technical scheme of the present invention rather than limits, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
