Lü Z, Yu Z, Luo W, Liu T, Wang Y, Liu Y, Liu J, Liu B, Gong L, Liu L, Li Y. Chromosome-level genome assembly and annotation of eel goby (Odontamblyopus rebecca). Sci Data 2024; 11:160. [PMID: 38307872 PMCID: PMC10837429 DOI: 10.1038/s41597-024-02997-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 01/25/2024] [Indexed: 02/04/2024] Open
Abstract
The eel gobies fascinate researchers with many important features, including its unique body structure, benthic lifestyle, and degenerated eyes. However, genome assembly and exploration of the unique genomic composition of the eel gobies are still in their infancy. This has severely limited research progress on gobies. In this study, multi-platform sequencing data were generated and used to assemble and annotate the genome of O. rebecca at the chromosome-level. The assembled genome size of O. rebecca is 918.57 Mbp, which is similar to the estimated genome size (903.03 Mbp) using 17-mer. The scaffold N50 is 41.67 Mbp, and 23 chromosomes were assembled using Hi-C technology with a mounting rate of 99.96%. Genome annotation indicates that 53.29% of the genome is repetitive sequences, and 22,999 protein-coding genes are predicted, of which 21,855 have functional annotations. The chromosome-level genome of O. rebecca will not only provide important genomic resources for comparative genomic studies of gobies, but also expand our knowledge of the genetic origin of their unique features fascinating researchers for decades.

[PMID: 37999175 PMCID: PMC10669881 DOI: 10.3390/biomimetics8070534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/04/2023] [Accepted: 11/06/2023] [Indexed: 11/25/2023] Open
Abstract
In nature, some fish can adhere tightly to the surface of stones, aquatic plants, and even other fish bodies. This adhesion behavior allows these fish to fix, eat, hide, and migrate in complex and variable aquatic environments. The adhesion function is realized by the special mouth and sucker tissue of fish. Inspired by adhesion fish, extensive research has recently been carried out. Therefore, this paper presents a brief overview to better explore underwater adhesion mechanisms and provide bionic applications. Firstly, the adhesion organs and structures of biological prototypes (e.g., clingfish, remora, Garra, suckermouth catfish, hill stream loach, and goby) are presented separately, and the underwater adhesion mechanisms are analyzed. Then, based on bionics, it is explained that the adhesion structures and components are designed and created for applications (e.g., flexible gripping adhesive discs and adhesive motion devices). Furthermore, we offer our perspectives on the limitations and future directions.
