The genomic annotation-related data for<i> Ochetobius elongatus.</i>

This data comes from Marine Ecological Genomics Lab, School of Marine Sciences, Sun Yat-Sen University, China.In this study, we assembled the chromosome-scale genome sequence of O. elongatus utilizing a combination of PacBio long reads and Hi-C technology. Following redundancy removal and Hi-C scaffolding, 99.83% of the assembly, totaling 881.6 Mb, was anchored to 24 pseudo-chromosomes, yielding a scaffold N50 of 35.1 Mb with 40 scaffolds. Annotation revealed 394.1 Mb of repetitive sequences, mainly composed of DNA transposons . A total of 28,674 protein-coding genes were predicted using a combined approach of homology-based, RNA-Seq-assisted, ab initio methods, with 28,637 genes (99.87%) annotated.
