Structure and evolution of the silver arowana genome. A Photo of a silver arowana used in this study. B A Circos plot of the genome-wide chromosome alignments. The tracks from outside to inside represent the position of chromosomes, GC content, and gene density, respectively. The center of these circles is the chromosome karyotyping of silver arowana. C,D Hi-C heatmap views of female and male individuals, respectively. E Syntenic relationships between silver arowana (upper) and two other arowana species, Asian arowana (S. formosus; center), and African arowana (H. niloticus; lower) with coding genes
