QINGDAO, Oct. 31 -- Chinese scientists have completed genome sequencing of saccharina japonica, whiteleg shrimp and Yesso scallop, opening possibilities for boosting quality and yield of the three species commonly harvested as seafood.
Scientists from the Ocean University of China and Sun Yat-sen University announced the discoveries on Wednesday at a conference in the eastern city of Qingdao in Shandong Province.
The genome of saccharina japonica, a type of kelp, is estimated to contain 35,725 genes which are larger than the genes of other eukaryotic algae, while Yesso scallop is estimated to have 29,650 genes in its genome, according to scientists.
Chinese scientists have previously mapped the genomes of four marine creatures, including oysters, large yellow croaker, grouper and tongue sole, which are widely cultivated in China for food or industrial use.
Saccharina japonica has medicinal effects and can be used to develop new drugs. It also contains seaweed glue and carrageenan, which are used in industries like dyeing and textiles, said Liu Tao with the Ocean University of China.
"Based on the study of their genome sequences, we may be able to improve the taste, yield and nutritional value of kelp and scallops, and raise the disease-resistance of whiteleg shrimp," Liu said.
