Abstract

Siganus guttatus and Siganus oramin are two major species that are naturally distributed along the Eastern Pacific coast and possess considerable ecological and economic value. Here, we present the construction and comparative analysis of the chromosome-level genomes of these two Siganus species. Employing a hybrid assembly strategy, we partitioned and independently assembled the PacBio, Illumina and Hi-C reads of S. guttatus and S. oramin, resulting in chromosome-level genomes. The assembly sizes (N50 size, BUSCO completeness) of the two genomes were 642.4 M (25.76 M, 98.26 %) and 502.8 M (16.98 M, 98.8 %) for S. guttatus and S. oramin, respectively, exhibiting high contiguity and integrity. This study marks the first successful assembly of chromosome-level genomes in Siganus species, along with an initial exploration of their dietary habits and habitats through comparative genomics analysis. These findings offer essential resources for comparative genomics and molecular evolution research.

期刊介绍： Genomics is a forum for describing the development of genome-scale technologies and their application to all areas of biological investigation. As a journal that has evolved with the field that carries its name, Genomics focuses on the development and application of cutting-edge methods, addressing fundamental questions with potential interest to a wide audience. Our aim is to publish the highest quality research and to provide authors with rapid, fair and accurate review and publication of manuscripts falling within our scope.
