Description
Technical field
The invention belongs to field of marine biotechnology, and in particular to a kind of gynogenesis abductive approach of stichopus japonicus.
Background technology
Artificial gynogenesis are conducive to quick foundation to be sheerly, therefore significant for the research of genetic breeding and fundamental biological knowledge.In terms of marine products economic shellfish, the research in the field relatively lags behind, and has only carried out the research of Artificial gynogenesis in nearly ten kinds of marine commercial molluscs at present.These researchs are mainly radiated or chemical method inactivating sperm by using various, so as to induce the gynogenesis of ovum.The homologous sperm inactivation method commonly used in research is difficult to exclude the interference of external source sperm genome, so there is scholar to attempt eliminating this interference, such as research in Chlamys farreri and disk Bao shellfish using Heterologous Sperm induction in recent years.But, Heterologous Sperm induction depends on the specificity of species, and influenceed by various environmental factors, the differing maturity of such as smart ovum, the excitement of other ovum also tends to asynchronous, if inactivation is insufficient, still there is the problem that sperm pollutes in fact, therefore limit its application in gynogenesis.
Compared with traditional homologous or Heterologous Sperm revulsion, electro photoluminescence revulsion does not need the participation of sperm in whole process, can thoroughly exclude the interference of external source sperm genome, is preferable abductive approach.The method has been widely used in the mammals such as rabbit, pig, mouse and ox and has achieved very big success.Its mechanism is by the way of electro photoluminescence, make to form reversible micropore in oocyte membrane, calcium ion in buffer solution enters ooecium matter along the concentration gradient of intraor extracellular, trigger the rapid transfer of calcium storehouse release calcium ion or kytoplasm calcium ion, so that simulating calcium ion regular wave phenomenon during normal fertilization starts egg development.But so far, the method there is no report in the research of marine organisms gynogenesis.This research is attempted inducing stichopus japonicus gynogenesis using electrostimulation first, and desk study is carried out to the cytological mechanism during its induction parameters and gynogenesis, it is intended to set up the technical method that electro photoluminescence induces stichopus japonicus gynogenesis.
The content of the invention
Regarding to the issue above, it is contemplated that setting up the technical method that electro photoluminescence induces stichopus japonicus gynogenesis.
A kind of gynogenesis abductive approach of stichopus japonicus, using electrostimulation, balances during ovum first is moved into electro photoluminescence buffer solution before electro photoluminescence
2min, mixes up electric impulser parameter, and drawing 1ml ovums with suction pipe is put into electric shock cup, you can carry out electro photoluminescence treatment；
The electro photoluminescence buffer solution is ZimmermanShi buffer solutions, and specific composition is：0.1 mmol/L Ca(C2H3O2)2H2O, 1 mmol/L K2HPO4, 0.5 mmol/L Mg (C2H3O2)2·4H2O, 0.1 mmol/L reduced glutathiones, 1% BSA, 0.4 mmol/L sucrose；
The electric impulser parameter is the kv/cm of field intensity 0.78, the μ F of electric capacity 5,2 electric pulses.
Ovum density during the electro photoluminescence is 7 × 104Individual/ml.
The cultural method of ovum and embryo is after electro photoluminescence：It is placed into the cm culture dishes of diameter 15 through the ovum after electro photoluminescence, with the filtering sea culture of thermophilic digestion, water temperature is kept for 20 DEG C, and culture density is every liter about 2 × 10 in each culture dish5Individual ovum；Initial stage of culture is gently agitated for seawater once per half an hour, and every 3 ~ 4h is stirred once later, to promote it to hatch.
2 hours cleavage rates of statistics each group after electro photoluminescence treatment, 24 hours statistics embryo survivals；
Total ovum number × 100% of ovum number/observation of cleavage rates or gynogenesis inductivity=generation spilting of an egg and discharge polar body；
Total ovum number × 100% of the primitive gut quantity/generation spilting of an egg of embryo survival=floating.
The method of the present invention is easy and effective, and after being induced through electro photoluminescence, the cleavage rates of stichopus japonicus can reach more than 28%, and embryo survival can reach more than 98%.
Specific embodiment
The present invention is described in further details with reference to specific embodiment.
The collection temporarily supported with smart ovum of parent
Stichopus japonicus is temporarily supported in 14 DEG C of circulating seawers after fetching, and individual the separating of male and female is temporarily supported.Feed bait.Heated up 1 DEG C daily during temporarily supporting, wait to produce to 16 ~ 17 DEG C of constant temperature.Ovum is obtained using light stimulation method, after after ovum output, first with 300 mesh silk cover filtering ovums, then with the silk cover filtering recovery of ova of 500 mesh, the density of the quantitative ovum of basis of microscopic observation after dilution.Needed to adjust the density of ovum according to experiment.
The electro photoluminescence treatment of stichopus japonicus ovum
The induction of ovum gynogenesis：Using electrostimulation, balanced during ovum first is moved into electro photoluminescence buffer solution before electro photoluminescence
2min, mixes up electric impulser parameter, and drawing 1ml ovums with suction pipe is put into electric shock cup, you can carry out electro photoluminescence treatment.
The electro photoluminescence buffer solution is ZimmermanShi buffer solutions, and specific composition is：0.1 mmol/L Ca(C2H3O2)2H2O, 1 mmol/L K2HPO4, 0.5 mmol/L Mg (C2H3O2)2·4H2O, 0.1 mmol/L reduced glutathiones, 1% BSA, 0.4 mmol/L sucrose.
The electric impulser parameter is the kv/cm of field intensity 0.78, the μ F of electric capacity 5,2 electric pulses.
Ovum density during the electro photoluminescence is 7 × 104Individual/ml.
The culture of ovum and embryo after electro photoluminescence
It is placed into the cm culture dishes of diameter 15 through the ovum after electro photoluminescence, with the filtering sea culture of thermophilic digestion, water temperature is kept for 20 DEG C, and culture density is every liter about 2 × 10 in each culture dish5Individual ovum；Initial stage of culture is gently agitated for seawater once per half an hour, and every 3 ~ 4h is stirred once later, to promote it to hatch.
