Description

A kind of tobacco root-knot Pathogen test examination based on loop-mediated isothermal amplification technique Agent box and its application method
Technical field
The invention belongs to plant disease technical field of detection of pathogeny, and in particular to one kind is based on loop-mediated isothermal amplification technique Tobacco root-knot pathogeny detecting reagent box and its application method.
Background technology
Tobacco root-knot is a kind of soil-borne disease for having a strong impact on tobacco leaf production.In recent years, for root-knot nematode Be present the drawbacks of high poison, high residue in most chemical nematicides of disease preventing and treating, worldwide generally disabled.Therefore adopt Safe and efficient root knot nematode disease preventing control method is taken to turn into trend of the times.During the prevention and control of tobacco root-knot, choosing It is considered as an economy, measure efficiently, green to select using suitable disease-resistant tobacco bred.However, root-knot nematode species are numerous More, different root-knot nematodes are different to the pathogenecity of host plant, and disease-resistant variety is also limited to the resistant range of root-knot nematode, when It is mainly peanut root-knot nematode that the most extensive root-knot nematode for endangering most serious is distributed on preceding domestic tobacco(Meloidogyne arenaria), Meloidogyne incognita(M. incognita)And javanese root knot nematode(M. javanica), these three root knot lines The form and molecular biological characteristics of worm are very much like, but larger Difference in Pathogenicity to different tobacco breds be present.Therefore it is accurate Really, the above-mentioned three kinds of root-knot nematodes of Rapid identification are seed selection and the precondition using disease-resistant tobacco bred.
Identify that the most frequently used method of root-knot nematode species is morphological method, this method cuts root by micromanipulation method Tie lines worm female adult pest perineal region cutin membrane, the difference for observing perineal region decorative pattern under the microscope determine the species of root-knot nematode. The advantages of this method is easy, directly perceived, and the drawbacks of existing is:1. root-knot nematode species are more, the perineal pattern of numerous species is special Point is easier to obscure so that the accuracy of identification fully relies on the experience of operator, and the probability of erroneous judgement is higher;It is 2. same There is individual difference in the perineal pattern of the root-knot nematode of class, the female adult pest progress to more than 20 is at least needed in practical operation Observation can just make a definite diagnosis, and take a lot of work, be time-consuming;3. Morphological Identification is only applicable to adult, it is not suitable for larva, and be separated in soil Root-knot nematode is present in the form of second instar larvae, and this method made is restricted in actual applications.In addition, isodynamic enzyme is electric Swimming method is also the method commonly used in root-knot nematode identification, and this method carries out poly- third with the protein crude extract administration of root-knot nematode female adult pest Acrylamide electrophoresis, should by carrying out species judgement according to the spectral pattern of enzyme band after esterase and Chances of Malic Dehydrogenase Isoenzyme dyeing It the shortcomings that method part overcomes Morphological Identification, can more fast and accurately judge root-knot nematode species, but still can only It is used as identification object with female adult pest.
Recently as the development of Protocols in Molecular Biology, quick, precise Identification is carried out to root-knot nematode using round pcr Turn into trend.Compared with morphology and isozyme electrophoresis authentication method, the PCR identification method scope of applications are more wide, root knot line Ovum, second instar larvae and the female male imago of worm all can be as the objects of identification.The PCR identifications of early stage include expanding using random primer RAPD-PCR technologies or using the PCR-RFLP for carrying out restricted digestion after the amplification of nematode universal primer to amplified production again Technology, their common drawback are due to cause the stability of identification and accurate using the special special primer of non-root-knot nematode Property is not high.Therefore, domestic and foreign scholars are started then expanded using root-knot nematode species Specific PCR primers to carry out root in recent years The Identification of Species of tie lines worm.The inventions such as Xu Jianhua《A kind of root-knot nematode rapid molecular detection primer and usage thereof》(The patent No.: ZL03131763.4), once built the invention such as quick《One authentication method for growing tobacco middle root-knot nematode》(The patent No.: ZL201610585565.X)The new method of tobacco root-knot pathogenic nematode PCR identifications is provided, this method uses three pairs of roots Knot line insect types special primer enters performing PCR detection to the root-knot nematode for being isolated from tobacco old complaint and soil respectively, and identification is convenient, accurate True rate is high, substantially increases the diagnosis efficiency of tobacco root-knot cause of disease.But as a result of Standard PCR detection method so that Qualification process is cumbersome, time-consuming, and needs instrument and equipment costly.
