Hokkaido University Kelp Lab
Machine-translated · View original
A lab that unravels the diversity of kelp and breeds strong strains.

AboutAbout the lab
Protecting and nurturing the diversity of kelp.
The Kelp Lab studies the diversity of plants of the order Laminariales (kelps) and their origins.
The coasts of the northwest Pacific are among the most kelp-diverse regions in the world. Using molecular biology methods, the lab investigates where Japanese kelps, which include many endemic species, came from and how they expanded their distributions.
To prepare for changes in growth environments, the lab identifies the genetic characteristics of various species, and also works on conserving genetic resources and breeding highly productive industrial species.
The lab is located in an annex of the Field Science Center for Northern Biosphere on the Sapporo Campus, and conducts its research using the Oshoro Marine Station in Otaru.
Key terms
- Laminariales
- A taxonomic group of brown algae that comprises the kelps. They grow large on rocky shores in cold seas.
- Phylogenetic classification
- Organizing organisms and dividing them into groups based on their evolutionary relationships.
- Breeding
- Creating new varieties by selecting or crossing individuals that have desired traits.
ResearchResearch themes
The lab surveys the diversity of Laminariales and clarifies their phylogenetic relationships and how their distributions have spread. It also works on conserving genetic resources in preparation for changes in growth environments, and on breeding more productive industrial species.

The coasts of the northwest Pacific are among the most kelp-diverse regions in the world. The lab surveys the diversity of Laminariales and infers the phylogenetic relationships among species.
*Illustrative imageWhere Did the Diversity Come From?
Using molecular biology methods, the lab investigates where Japan's kelps, which include many endemic species, came from, and how they expanded their distributions and diverged.
*Illustrative imageConserving Genetic Resources and Breeding
In preparation for possible future changes in the growth environments of kelps, the lab identifies the genetic characteristics of each species and strain and conserves genetic resources. It also works on breeding to create more productive industrial species.
