Description
Technical field
The present invention relates to the methods that a kind of couple of fish embryo carries out Ploidy Identification.
Background technique
Fishes Chromosomes operating technology (gynogenesis and multiploid induction) plays important in aquatic livestock breeding field
Effect.Currently, the research work in relation to multiploid induction makes much progress in the world.The seas such as salmon trout class, flounder flounder class, Tilapia mossambica,
Triploid is induced in freshwater fish, in salmon fishes oneself obtain Atlantic salmon, rainbow trout (Salmo gairdneri), rainbow trout, hump back salmon,
The autotriploids such as king salmon and America red dot.It is domestic in recent years also successfully to have induced triploid megalobrama amblycephala, water
Brilliant coloured silk crucian carp, red porgy, black porgy, lefteye flounder and rainbow trout, especially in last century the eighties mid-term to the nineties initial stage, China Water obstetrics
It learns research institute Heilungkiang aquatic products research institute and has just carried out rainbow trout female Cultivating techniques research entirely, and the beginning of this century completes three times of rainbow trout
System kind technical research, tentatively realizes the large-scale production of triploid;Later, China Aquatic Science Research Institute Heilungkiang aquatic products
Research institute has also carried out the research of triploid Oncorhychus masou and triploid golden trout seeding technique.
There are many kinds of related fish methods for ploidy determination, comprising: chromosome counting method, red blood cell and nucleus volume measurement
Method, nucleolus organizer region's silver staining counting method, body cell DNA relative amount measuring method etc..Chromosome technique method needs to obtain Fish
Cell mitogen division phases (karyotype), by matching to chromosome, hand picking goes out all homologous dyes
Colour solid, and counted, and a kind of method for identifying the ploidy of fish is compared with reference genome, this method is current
Generally acknowledged most accurate fish methods for ploidy determination, but due to there are mitosis metaphase split coil method be prepared into power it is low with it is same
The artificial judgement of source chromosome pairing there are error probabilities high, level-one complex steps and it is professional too strong the features such as, be not suitable for carrying out
It is not very practical especially to carry out the screening of high-volume polyploid in production practice for mass detection.Red blood cell and nucleus volume
Mensuration and nucleolus organizer region's silver staining counting method measurement ploidy accuracy are lower, and after being not readily used for batch processing induction polyploid
The Ploidy Identification in generation.
When development Fishes Chromosomes double experiment, need effectively to assess set experiment condition, such as press
Power intensity, pressure effect time and after fertilization pressure intervention window phase etc.;And more times are being carried out for seed initiative enterprise
Also ploidy verifying is carried out to the polyploid seed of preparation in body scale production of hybrid seeds production, require a set of stabilization, quickly and just
Prompt methods for ploidy determination, especially in embryo stage.Because polyploid Seedling production enterprise will be while selling out seed
A times implementations are known at the first time.Currently, being all equal production of hybrid seeds offspring to the assessment of fish gynogenesis and multiploid induction result
It is developed to young stage and carries out Ploidy Identification again later, then assesses the superiority and inferiority that genome walking tests set parameter and condition.
Thus there are some defects: (1) since gynogenesis and multiploid induction technology offspring obtained must wait until to enter juvenile fish
Stage just can be carried out Ploidy Identification, and especially as salmon trout is long growth cycle, development to juvenile fish stage needs 6 months, this causes must
Palpus etc. is lot more time to the result of assessment genome walking experiment;(2) before due to assessment ploidy operation experiments result, have longer
One section of breeding process, in this process because caused by the reasons such as breeding environment variation, cultural technique and disease fish it is dead
Be it is unpredictable, the offspring of genome walking experiment preparation does not have equal detections, and just all dead cases also can be found everywhere.
Summary of the invention
In order to shorten the Ploidy Identification period, production loss caused by extraneous factor in breeding process is avoided, the present invention
Provide the method that a kind of pair of salmon trout embryo's living body carries out Ploidy Identification.
The method that the present invention carries out Ploidy Identification to salmon trout embryo's living body is as follows:
One, salmon trout eyespot phase embryo is individually temporarily put under the conditions of 5~8 DEG C, and keeps embryo's air exchange not anoxic;
Two, salmon trout eyespot phase embryo is pierced through with tip tweezers, releases the liquid fat in ovum, is pressed from both sides later with tweezers
Live in embryo stirs in PBS buffer solution and washes excess oil, is subsequently placed in the nucleus dye liquor of culture dish, by ovum skin and work
The chopping of body embryo tire shakes up embryonic cell suspension is made;
Three, it rinses culture dish with nucleus dye liquor to mix with step 2 embryonic cell suspension, then with 30 μm of aperture strainers
Embryonic cell mixing suspension is filtered;It takes filtrate to be refiltered once with 30 μm of aperture strainers, obtains detection sample;
Four, the known salmon trout diploid sample of dyeing is detected with the ploidy analyser, and adjusts fluorescence signal value to 100
Place is set as check sample;It is detected after will test sample dyeing with the ploidy analyser, records fluorescence signal value, it is included by machine
Analysis system, will test the peak value figure mean value of sample compared with check sample peak value figure, determine detection sample ploidy size.
The present invention carries out Ploidy detection and identification in embryo stage, can carry out without until offspring enters juvenile fish stage
Detection cycle is greatly shortened in Ploidy Identification, knows ploidy in fertilized eggs period, can do the production of hybrid seeds of polyploid again in due course.For
Aquaculture enterprise and research institution can carry out a large amount of and multiple batches of identifications in breeding period, due to the fish oosperm incubation period
It is longer, therefore obtain qualification result in embryo stage, breeding period is carried out again the preparation of multiple polyploid be it is extremely beneficial and
It is feasible.
The present invention is short to the pre-treatment, dyeing and detection time of test sample, easy to operate, quick, identification stability it is good,
Accuracy rate is high, dyeing drug dosage is small, the micro- poison of operation toxicity, to body fanout free region, be suitble to the mass detection of industrialization production
With identification, it is more conducive to polyploid breeding practice and polyploid large-scale production needs.The method of the present invention is universal for technology
Stronger with promoting, without profession, upper machine personnel are assisted, independent training i.e. detection operation in 20 minutes.
