Description

The molecular specificity labeled primers and discrimination method of straw berry tomato
Technical field
The invention belongs to identify the technology neck of straw berry tomato Physalis pubescens L. using molecular biology method Domain, be related to it is a kind of identify straw berry tomato specificity labeled primers and it is a kind of using the specific primer to straw berry tomato carry out fastly Speed mirror method for distinguishing.
Background technique
Straw berry tomato (Physalis pubescens L.), alias Huang mushroom creeping plant, Mushroom ma are Solanaceae (Solanaceae) acid Slurry belongs to (Physalis) annual herb plant.It originates in America, in China Jilin, Heilungkiang, Liaoning and the Eastern Inner Mongolia southeast Fringe region have cultivation or ease be it is wild, be born in by meadow or field wing more.Straw berry tomato is a kind of very important medical, edible Have both plant.As folk tradition Chinese medicine simply, straw berry tomato is included earliest in Shennong's Herbal, is listed as middle product, band Calyx fruit or herb are known as Chinese lantern, and nature and flavor acid is flat, enters lung channel, have effects that clearing heat and detoxicating, diuresis hemostasis, can cure the parotid gland Inflammation, abscess of throat, difficult urination and cough with lung heat, etc..Other than medicinal efficacy, straw berry tomato is also act as high-grade novel nourishing Health care " herbal fruit ", fruit faint scent is palatable, sweet and delicious, vitamin C rich in, carrotene, calcium, iron in fruit It is full of nutrition Deng the amino acid that 20 several mineral materials and 18 kinds of needed by human body are wanted, it is favored by people.In addition, physalis pubescens fruit Also processable that fruit juice, candied fruit, can etc., unique flavor is made, adult children are fond of, are suitable for people of all ages.Monkey flower (hair Wintercherry Physalis pubescens, small wintercherry P.minima, Ku Zhi P.angulata and wintercherry Physalis alkekengi Var.franchetii morphological feature) is extremely similar, is difficult using conventional sorting methods by straw berry tomato and other Physalis Similar plant distinguishes.Therefore, by other monkey flowers be mistakenly considered straw berry tomato carry out using the case where happen occasionally, this is hair The safe handling and protection of wintercherry resource bring very big difficulty.
DNA molecular marker especially specific molecular marker technology makes up and overcomes some defects of conventional sorting methods And problem, it can be analyzed by gene order comparison in difference and provide direct evidence for plant identification, genealogical classification.This patent is first SCoT molecular marking technique is first used, monkey flower SCoT finger-print is obtained using round pcr.By largely screening examination It tests, obtains straw berry tomato specific band, by the methods of gel extraction, TA clone, sequencing, exploitation devises fast for straw berry tomato Speed identify specificity labeled primers, for straw berry tomato germ plasm resource it is accurate identify and protect provide effective molecular engineering according to According to.So far, there has been no molecular specificity markers to be applied to the research report that straw berry tomato identifies.
Summary of the invention
First purpose of the invention is in view of the deficiencies of the prior art, to provide the molecular specificity labeled primers of straw berry tomato (ST3MSJF/ST3MSJR), the specificity labeled primers sequence is as follows:
Upstream primer ST3MSJF:5 '-ATTGATAGGGTAAACCATG-3 ', as shown in SEQ ID NO.1;
Downstream primer ST3MSJR:5 '-CTGTAATAAAACAAAAGCG-3 ', as shown in SEQ ID NO.2.
Primer combination is, by a large amount of screening experiments, to be marked using SCoT using Standard PCR technology and obtain straw berry tomato spy Specific DNA-fragments obtain the DNA sequence dna by gel extraction, TA clone, sequencing, design straw berry tomato specificity on this basis Labeled primer carries out PCR amplification with the primer pair monkey flower, only reacts with straw berry tomato sample DNA, obtain 1479bp The specific fragment of size, without with other monkey flower example reactions.It is anti-by Standard PCR with the specific primer It can should quickly identify hirsutic acid slurry samples.
A second object of the present invention is to provide the methods that above-mentioned molecular specificity labeled primers identify straw berry tomato.This method Are as follows: specificity amplification primer is used as using above-mentioned primer combination (ST3MSJF/ST3MSJR), with monkey flower genome to be measured DNA is template, carries out PCR amplification, carries out electrophoresis detection to amplified production, if it is 1479bp size that molecular weight, which occurs, in electrophoresis result Specific fragment, then monkey flower sample to be measured is straw berry tomato, on the contrary then be not.
Specific the method for the invention is as follows:
(1) extraction of genomic DNA: the fresh blade 100mg of clip monkey flower sample to be measured is put into mortar, immediately plus Enter liquid nitrogen grinding to powder, then (is purchased from the raw work biology in Shanghai using UNIQ-10 pillar plant genome DNA extraction agent box Engineering Co., Ltd) genomic DNA is extracted, gained DNA carries out electrophoresis detection with 0.8% agarose gel, and with ultraviolet spectrometry light Degree meter detectable concentration, is diluted to 50ng/ μ l.
(2) genomic DNA extracted using step (1) is template, with the molecular specificity labeled primers (ST3MSJF/ ST3MSJR it) is used as amplimer, carries out PCR amplification.
PCR amplification system (20 μ l of total volume): 2 μ l 10 × Buffer, 2 μ l MgCl2(25mM), 0.8 μ l dNTPs (10mM), 1 μ l primer ST3MSJF (10 μM), 1 μ l primer ST3MSJR (10 μM), 1 μ l template DNA (50ng/ μ l), 0.5 μ l Taq enzyme (2U/ μ l), 11.7 μ l ddH2O。
PCR response procedures: 94 DEG C of initial denaturation 5min;(94 DEG C of denaturation 50s, 56 DEG C of annealing 50s, 72 DEG C extend 35 circulations 1.5min);72 DEG C of extension 10min.
(3) electrophoresis detection is carried out to step (2) PCR product using 1.5 ﹪ Ago-Gels, taken pictures through gel imaging system Detection, if the DNA band that molecular weight is 1479bp size occurs in electrophoresis result, sample to be tested is straw berry tomato, on the contrary then be not.
Laboratory sample dosage of the present invention is few;As a result accurate, high sensitivity, ST3MSJF/ST3MSJR are straw berry tomato specificity Amplimer is negative reaction if other monkey flower samples;Method is easy, is detected using Standard PCR technology, It is time-consuming short, it can be completed within 1st.
Detailed description of the invention
Fig. 1 be using the specificity labeled primers ST3MSJF/ST3MSJR that designs of the present invention to monkey flower sample into Electrophoretogram after row PCR amplification, wherein M is DNA molecular amount standard marker DL2000;Channel 1~4: small wintercherry P.minima;5~13: Ku Zhi P.angulata;14~17: wintercherry P.alkekengi var.franchetii;18~20: hair Wintercherry P.pubescens.Electrophoretogram shows that only straw berry tomato sample amplification goes out the specific DNA item that molecular weight is 1479bp size Band.
Specific embodiment
The present invention more can fast and accurately identify hirsutic acid slurry samples from molecular level, by following embodiment to this Invention is described further, but protection scope of the present invention is not limited to that:
