연체동물의 유전체 및 전사체 연구 동향 (2020년)

Abstract

With the help of Next-Generation Sequencing (NGS) technology, comprehensive genomic and transcriptomic studies have been conducted by researchers working on mollusks around the world. Base on March 2020 data at the GOLD database, 237,877 genetic projects have been registered. It shows that these results are about 4 times higher than the data reported in 2015, meaning that the genetic projects have been steadily conducted with various species. Among them, a total of 71 cases were registered for mollusks (37 cases of bivalves, 28 cases of gastropoda, and 6 cases of cephalopoda). The genome project for mollusks has increased by about 30 cases compared to 2015, mainly in the United States and China. Besides, analysis of the genetic resources registered in the NCBI for ten years indicated that the genome projects have quadrupled depending on the type of database. In case of sequence read archive (SRA) database, 18,476 mollusks-related genomic studies (about 34.7 TB) have been registered. About 66 GB of data was registered by 2010, and also about 32,532 GB was registered from 2011 to 2019, meaning that there is a 500-fold increase over the decade. Taken together, it is expected that genomic research on mollusks will have many advantages such as the preemption of genetic resources.
