Summary of the invention
The present invention provides a kind of method of yellow tail silver xenocypris paternity test, establishes yellow tail silver xenocypris paternity test technology using microsatellite,
Accuracy is high, can be used for yellow tail silver xenocypris later period individual identification, carries out the recruitment evaluation of enhancement releasing;It can also carry out Population Genetics
Analysis, the decline to its inbreeding and germ plasm resource is effectively prevent.
The method of yellow tail silver xenocypris paternity test, comprising:
(1) Huang tail silver xenocypris individual DNA is extracted: extracting yellow tail silver xenocypris parent and daughter DNA is spare;
(2) by high-flux sequence, 59 pairs of microsatellite markers of acquisition the screening of yellow tail silver xenocypris microsatellite marker: are subjected to PCR expansion
Increase, the high primer further progress temperature gradient screening analysis of polymorphism is isolated in screening;
(3) synthesis and PCR amplification of yellow tail silver xenocypris micro-satellite primers fluorescent marker: the 16 pairs of polymorphisms screened are high and can stablize
The microsatellite marker of amplification, puts on two kinds of fluorescent primers respectively, after PCR amplification, reads allele value;
(4) it the foundation of yellow tail silver xenocypris paternity test technology: selects one group of Huang tail silver xenocypris individual and individually carries out fertilization and hatching cultivation, extract
30 individual DNA choose breeding 33 tail of parent and establish paternity test system for candidate parent as progeny population, carry out
Paternity test analysis.
1 16 pairs of table yellow tail silver xenocypris microsatellite marker features
Preferably, step (3) Huang tail silver xenocypris paternity test PCR reaction system are as follows:
Preferably, yellow tail silver xenocypris paternity test PCR reaction condition are as follows:
94 DEG C of initial denaturation 5min;94 DEG C of denaturation 45s, anneal 45s under the annealing temperature of respective primer, 72 DEG C of extension 90s, and 35
A circulation;72 DEG C re-extend 10 min, 4 DEG C of preservation PCR products.
The present invention also provides yellow tail silver xenocypris paternity test kits, and the paternity test of yellow tail silver xenocypris may be implemented.
Kit (100 specifications) forms as follows:
The invention has the benefit that the present invention establishes yellow tail silver xenocypris paternity test technology using microsatellite, accuracy is high, Ke Yiyong
It is assessed in the enhancement effect in yellow tail silver xenocypris later period, inbreeding and the decline of germ plasm resource can also be effectively prevent.
Specific embodiment
It is specifically described below to further appreciate that the contents of the present invention, feature:
The method of yellow tail silver xenocypris paternity test, comprising:
One) Huang tail silver xenocypris individual DNA is extracted
Yellow 33 tail of tail silver xenocypris parent population tail fin sample of acquisition, 30 tail of filial generation, absolute alcohol room temperature preservation are spare.Reagent is extracted using DNA
Box extracts DNA, carries out DNA concentration measurement by NanoDrop2000, after be diluted to 100ng/ul and save backup.
Two) screening of yellow tail silver xenocypris microsatellite marker:
By high-flux sequence, 59 pairs of microsatellite markers of acquisition are subjected to PCR amplification, utilize 12% polyacrylamide gel electricity
Swimming carries out preliminary screening separation, obtains 16 pairs of polymorphisms height and can stablize the microsatellite marker of amplification, further progress temperature
Degree gradient screens and carries out population analysis;
Three) synthesis and PCR amplification of yellow tail silver xenocypris micro-satellite primers fluorescent marker:
Screening obtains 16 pairs of polymorphisms height and can stablize the microsatellite marker (table 1) of amplification, puts on two kinds of fluorescent primer (5- respectively
HEX and 5-FAM), after PCR reaction system amplification in table 2, product is read after 1% agarose gel electrophoresis Preliminary detection
Take allele value.
Four) foundation of yellow tail silver xenocypris paternity test technology
Yellow tail silver xenocypris whole artificial propagation offspring selects one group of individual and individually carries out fertilization and hatching breeding, and 30 tails are chosen in the filial generation of generation
DNA extraction is carried out, while being used for paternity test Establishing for other breeding 31 tails of parent as candidate parent.Utilize cervus
3.0 software statistics allele categories, heterozygosity (H 0 ), expectation heterozygosity (He), polymorphism information content (PIC), average elimination factor
With accumulative elimination factor.It see the table below 3.
3:16 microsatellite marker number of alleles of table, observation heterozygosity (Ho), expectation heterozygosity (He), polymorphism information contain
It measures (PIC), the accumulation probability of exclusion of the first parent, the second parent accumulation exclusion generally and parents accumulates probability of exclusion.
Using 30 individuals as progeny population, it is assumed that 33 tail candidate parents are the parent of this 30 offspring individuals, with sieve
The yellow tail silver xenocypris microsatellite of 16 pairs selected carries out simulation paternity test, samples 10000 times, does not know to carry out modeling point with Parent
Analysis, while choosing other breeding 33 tails of parent individual as candidate parent for establishing paternity test system, respectively with maternal or
Male parent is known, Parent is known and the unknown modeling of Parent carries out paternity test analysis, and PRELIMINARY RESULTS is shown, the first parent
Accumulation probability of exclusion (combined exclusion probability of the first parent, CE-1P), second
Parent accumulate probability of exclusion (combined exclusion probability of the second parent, CE-2P) and
Parents accumulate probability of exclusion (combined exclusion probability of a parent pair, CE-PP)
0.99807593,0.999983 and 0.99999999.30 offspring individuals accurately find parent, and paternity test result is shown in
Table 4.
Shown in above-mentioned 30 individual paternity test results, wherein LOD value is parent-offspring's index (paternity index)
Logarithm, meaning of the LOD greater than 0 is that compared with any parent, candidate parent is most likely to be true parental generation.Above-mentioned knot
Fruit shows that 30 individuals accurately have found real male parent and maternal respectively YM1 and YF1, and the above analysis result confirms
It is feasible that this 16 yellow tail silver xenocypris microsatellite markers, which are used for yellow tail silver xenocypris paternity test,.
The above method is utilized in summary, and the paternity test of yellow tail silver xenocypris may be implemented, formed according to agents useful for same in method
Kit for yellow tail silver xenocypris paternity test.Kit (100 specifications), such as the following table 5.
