Description
Technical field
The invention belongs to species identification and Chinese medicine true and false authentication technique field.More particularly, to a kind of quick discriminating
The method for identifying molecules of the muscardine true and false in Chinese medicine stiff silkworm.
Background technology
The larva of a silkworm with batrytis (Bombyx mori), the larva in Bombycidae insect silkworm (Bombyx mori Linnaeus) 4~5 ages
Infect (or artificial infection) muscardine beauveria bassiana (Bals.) Vuillant and lethal hirudo leech (national medicine
The allusion quotation committee, 2015).Muscardine in the larva of a silkworm with batrytis is the disease fungus that a class parasitizes insect, according to NCBI latest datas,
Muscardine is ranged:Double-core suberathem (Dikarya), Ascomycota (Ascomycota), cup fungi subphylum
(Pezizomycotina), excrement shell Gammaproteobacteria (Sordariomycetes), meat seat bacterium subclass (Hypocreonycetidae), meat seat
Zoopagales (Hypocreales), cordyceps sinensis Cordycepps (Cordycipitaceae), Cordyceps (Cordceps).
The larva of a silkworm with batrytis is as the traditional Chinese medicine of China, with hypoglycemic, reducing blood lipid, anticancer, anticonvulsion, anti-freezing, antibacterial, town
The multiple pharmacological effects such as quiet hypnosis, whitening, so that it has important effect on clinical treatment.Current peasant household's cultivation is stiff
The income that silkworm is brought be it is very considerable, can as farmer richness good approach (Zhang Weiji, 2016).However, due to stiff silkworm
With important pharmacological action and good economic benefit so that some businessmans in order to obtain more interests, start with personation and
Unqualified stiff silkworm serves as qualified stiff silkworm.Traditional adulterant stiff silkworm is mostly that dead silkworm is mixed into white process with limewash at present
(Zhao Qiyou, 1998), also has and pretends to be certified products stiff silkworm to use (Hu great Ze etc., 2003) cutworm, in recent years, occur in that new adulterant
Black dead silkworm and hollow stiff silkworm.Due to the outward appearance, micro- etc. similar to certified products of adulterant stiff silkworm, it is difficult to had using conventional method
Effect differentiates, in order to prevent the appearance of such phenomenon, and its true and false differentiates to be particularly important in larva of a silkworm with batrytis performance rating work.
The stiff silkworm Quality evaluation of present mainly includes two kinds, and one is physical characterization method, including appearance identification
With microexamination (Xu state equalization, 1996;Chinese Pharmacopoeia Commission, 2015), microsublimation method (Huang Xiaoxue, 2005), SDS-
PAGE (Qiu Yi, 2014), grey Relational Analysis Method (Li Feng, 2011), ultraviolet fingerprint (Ji Xianling, 2006), infrared finger
The methods such as line collection of illustrative plates (Ji Xianling, 2007), high performance liquid chromatography (Wang Gengxian, 2006) are identified stiff silkworm quality of medicinal material;
Two be method for identifying molecules, the base thing based on COI sequences and ITS sequence respectively to stiff silkworm medicinal material such as mainly Jia Jing (2016)
Plant silkworm and muscardine is identified, so that the quality and quality to the larva of a silkworm with batrytis are identified.Wherein, Molecular Identification has more accurate
Really, easy to operate the features such as, application prospect is more preferable.
At present to muscardine authenticity aspect in stiff silkworm, the primer of special checking muscardine is lacked always, lacks a kind of
The method for identifying molecules of the muscardine true and false in quick discriminating Chinese medicine stiff silkworm.
The content of the invention
The technical problem to be solved in the present invention is the defect and deficiency for overcoming existing stiff silkworm authenticity technology, is completed to wide
The high-flux sequence of eastern strain muscardine mitochondria whole genome sequence, compares muscardine Mitochondrial gene sequence in geographical kind
Difference, it is found that the ribosomal protein gene rps3 variations of muscardine are obvious;And based on muscardine mitochondria rps3 gene orders
Primer is designed, the primer of specific amplified fungi muscardine is found there is provided a kind of molecule labelling method of unique identification muscardine, from
And in quick discriminating stiff silkworm muscardine the true and false, be on Chinese medicine stiff silkworm clinical application trouble free service provide molecular engineering support.
It is an object of the invention to provide the ribosomal protein gene rps3 sequences of muscardine.
Another object of the present invention is to provide the primer sets of the muscardine true and false in one group of identification checking stiff silkworm.
Still a further object of the present invention is to provide a kind of method for identifying molecules of the muscardine true and false in quick discriminating Chinese medicine stiff silkworm.
Another object of the present invention is to provide a kind of kit of the muscardine true and false in quick discriminating Chinese medicine stiff silkworm.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
The present inventor completes the line grain to Guangdong Strain muscardine mitochondria genome sequencing and 13 cordyceps sinensis section species
On the basis of body full-length genome bioinformatics comparative analysis, it is found that the ribosomal protein gene rps3 variations of muscardine are obvious,
And based on the design screening of Guangdong Strain muscardine mitochondrial rps3 gene orders obtained 1 to can specific detection muscardine draw
Thing.
The primer sets of the muscardine true and false in one group of identification checking stiff silkworm, are primer pair F935 and R1385, and sequence is respectively such as
Shown in SEQ ID NO.1 and SEQ ID NO.2.
Application of the primer sets in identification checking stiff silkworm in the muscardine true and false, is building quick discriminating Chinese medicine stiff silkworm
