A recent study published in the international journal 'Nature Ecology and Evolution' by the Ministry of Oceans and Fisheries of Korea, in collaboration with Sungkyunkwan University, has revealed that cultured seaweed has a higher genetic diversity than its wild counterpart. This research, part of the 'Post Genome Multi-Ministry Genome Project' since 2014, has challenged the conventional wisdom about the lower genetic diversity of aquaculture varieties compared to wild ones. The findings suggest that Korean seaweed, introduced in Europe and New Zealand, has lower genetic diversity due to a limited gene pool. However, Korean seaweed, whether wild or farmed, shows a higher genetic diversity than its counterparts in Europe and New Zealand, highlighting the effective preservation of genetic diversity during breeding in Korea despite the long history of seaweed cultivation starting in the 1970s. This research aims to further analyze the genetic diversity of seaweed from around the world to clarify origins, identify distribution characteristics, and migration routes, with the ultimate goal of accelerating the development of new seaweed varieties and supporting the bioindustrialization of seaweed.
