Problems solved by technology

However, the probability of natural mutations is usually very small, and it is difficult to find individuals with non-moving eyes for comparative research, while larvae soaked in thiourea cannot complete metamorphosis and still maintain the shape of larvae, and thyroid hormones may regulate the growth and development of related tissues , so the method of thyroid hormone suppression can not achieve the expected purpose

Abstract

The invention discloses a method for inhibiting the movement of flounder eyes, which comprises the selection of an inhibiting drug, i.e. colchicine, the method and the skill of microinjection, and the position and the time for injecting paralichthys, solea and cynoglossus semilaevis. The method can restrict the action of the drug in the local tissues so as to achieve better action and effect. Themovement of the flounder eyes is inhibited by injecting the colchicine, the generation of other metamorphosis events can be not influenced, and the method can provide the experimental materials to the research of the mechanisms asymmetrical occurrence.

Description

technical field [0001] The invention relates to a method for inhibiting eye movement of flounder, which comprises injecting colchicine into flounder larvae before metamorphosis, as well as the concentration and dose of colchicine, the injection method, the injection time and the injection site. It can be used to breed flounder whose eyes do not move but other metamorphosis events are normal, and to provide flounder with bilateral symmetry for the field of scientific research. Background technique [0002] Flounder is the general term for flatfishes. Both eyes are located on one side of the body. Among the bilaterally symmetrical vertebrates, the left-right asymmetry of flatfish is a special case. The establishment of body asymmetry in flatfish is crucial to the normal development of tissues and organs, and larvae that fail to establish asymmetry in production will die in large numbers. In addition, the establishment of body asymmetry is crucial to the normal development of ...
