AI Article Synopsis
- The Indian oil sardine (Sardinella longiceps) is an important small fish found in the Northern Indian Ocean, and its genome has been thoroughly sequenced using modern technologies.
- The genome is 1.077 Gb in size, with a high-quality assembly showing 93.5% completeness, and it includes 46,316 predicted protein-coding genes.
- This fish is also nutritionally valuable due to its high omega-3 polyunsaturated fatty acids, and key genes related to omega-3 biosynthesis have been identified, though their functionality still needs to be confirmed.
Article Abstract
The Indian oil sardine, Sardinella longiceps, is a widely distributed and commercially important small pelagic fish of the Northern Indian Ocean. The genome of the Indian oil sardine has been characterized using Illumina and Nanopore platforms. The assembly is 1.077 Gb (31.86 Mb Scaffold N50) in size with a repeat content of 23.24%. The BUSCO (Benchmarking Universal Single Copy Orthologues) completeness of the assembly is 93.5% when compared with Actinopterygii (ray finned fishes) data set. A total of 46316 protein coding genes were predicted. Sardinella longiceps is nutritionally rich with high levels of omega-3 polyunsaturated fatty acids (PUFA). The core genes for omega-3 PUFA biosynthesis, such as Elovl 1a and 1b,Elovl 2, Elovl 4a and 4b,Elovl 8a and 8b,and Fads 2, were observed in Sardinella longiceps. The presence of these genes may indicate the PUFA biosynthetic capability of Indian oil sardine, which needs to be confirmed functionally.
