Embodiment 1

[0027] Embodiment 1, be used for the synthesis of the barcode primer set of identification virus species in the tobacco mosaic virus genus

[0028] Taking the representative species of 22 species of Tobacco mosaic virus in Genbank as the virus voucher samples, the conserved region of its sequence was analyzed. The primer sets Tobamo F6 and Tobamo R6 were designed and synthesized by variability to identify the species of Tobamovirus. The length of the amplified product of the barcode primer set was 200bp.

[0029] The nucleotide sequence of Tobamo F6 is sequence 1 in the sequence listing, and the nucleotide sequence of Tobamo R6 is sequence 2 in sequence listing China.

Embodiment 2

[0030] Embodiment 2, barcode primer set identifies the virus species of Tobamovirus genus

[0031] 1. Identification of Tobacco Mosaic Virus Species by Barcode Primer Set

[0032]In order to verify the versatility of the barcode primer set used to identify Tobamovirus prepared in Example 1, the present embodiment selects from watermelon, pepper, pumpkin, tomato, kidney bean, tobacco and cucumber samples with obvious mosaic symptoms. Four Tobamoviruses (pepper light mottle virus, cucumber green mottle mosaic virus, tobacco mosaic virus and tomato mosaic virus) were evaluated.

[0033] Pepper mild mottle virus (Pepper mild mottle virus): recorded in "Detection of Pepper Mild Mottle Virus in Pepper Seeds. Anhui Agricultural Sciences, 2007, 35(14): 4228-4229." obtained by the Institute.

[0034] Cucumber green mottle mosaic virus: recorded in the article "Occurrence of Cucumber green mottle mosaic virus on Cucurbitaceous Plants in China. Plant disease, 2009, 93(2): 200." The pub...

Abstract

The invention discloses a method for authenticating the species of tobacco mosaic viruses and a special bar code primer thereof. A bar code primer group provided by the invention consists of Tobamo F6 and Tobamo R6. An experiment shows that by the use of the primer group provided by the invention, a sample for representing the symptom can be amplified to tobacco mosaic virus type viruses by 100 percent, and the sequencing success rate is 100 percent; the method can be used for effectively performing species authentication on the viruses in the species. The special bar code primer can be applied to quarantine of imported plants and products of the imported plants, and virus introduction is prevented; the special bar code primer can be also popularized and applied to a plant protection and detection station, a scientific research institution, an agricultural production enterprise and a peasant household in a large range in China.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for identifying tobacco mosaic virus species and special barcode primers thereof. Background technique [0002] The genus Tobamovirus is a member of Virgaviridae of the order Tymovirales; according to the latest virus classification ninth published by the International Committee Taxonomy of Viruses (ICTV) in 2012 According to the second report, the virus genus includes Brugmansia mild mottle virus (BrMMV), cucumber fruit mottle mosaic virus (CFMMV), cucumber green mottle mosaic virus (Cucumber green mottle mosaic virus). virus, CGMMV), Frangipani mosaicvirus (FrMV), Hibiscus latent Fort Pierce virus (HLFPV), Hibiscus latent Singapore virus (HLSV), Kyuri green mottle mosaic virus (Kyuri green mottle mosaic virus, KGMMV), Obuda peppervirus (ObPV), Odontoglossum ringspot virus (ORSV), Paprika mild mottle virus (PaMMV), Pepper mild Pepper mild mottlevirus (PMMoV), ...
