Marine Life Genetic Information Lab
Machine-translated · View original
A lab that makes use of fish genetic resources through developmental biology, breeding, and computational methods.
AboutAbout the lab
Using fish genetic resources while conserving them
The Marine Life Genetic Information Lab conducts research aimed at making effective use of fish genetic resources.
Unlike mineral resources, genetic resources can be used almost indefinitely if they are properly managed.
The lab studies the mechanisms of development, growth, and metamorphosis in aquatic organisms at the molecular level. It also works on genetic breeding, the conservation of genetic resources in wild populations, and the development of computational methods for comparing nucleotide sequences.
In addition, the lab develops experimental methods, such as genome editing, for studying gene function in non-model organisms, including Japanese flounder.
Key terms
- Metamorphosis
- A process in which larvae or juvenile fish greatly change their body form and structure partway through growth
- Genome editing
- A technology for rewriting an organism's genetic information at a targeted site
- Genetic breeding
- A method of establishing strains that carry useful genes and using them to improve varieties
ResearchResearch themes
The lab aims to make effective use of fish genetic resources. Centered on the molecular regulation of development, growth, and metamorphosis, genetic breeding and the conservation of genetic resources, and the development of methods for comparing nucleotide sequences, it conducts research on species such as Japanese flounder, char, and ayu.
*Illustrative imageMolecular regulation of development, growth, and metamorphosis
To improve production techniques in fish aquaculture, the lab seeks to clarify the molecular mechanisms that regulate the development, growth, and metamorphosis of eggs, larvae, and juvenile fish.
*Illustrative imageGenetic modification to alter fish traits
Aiming to deliberately alter fish traits, the lab conducts research applying genetic modification and gene transfer technologies.
*Illustrative imageGenetic breeding and conservation of genetic resources
The lab studies genetic breeding, which establishes strains carrying useful genes so they can be used efficiently, and conservation, which protects the genetic resources of wild populations that serve as breeding material.
*Illustrative imageComputational methods for comparing nucleotide sequences
The lab works on developing computational methods for efficiently comparing nucleotide sequences with one another.
