Figure 1. Basic information of Fenneropenaeus chinensis.(a) F. chinensis. Male above and female below, both are sexual maturity. (b) Heatmap of anchored chromosomes (c) Genomic characteristics of F. chinensis . Track 1 (from the outer-ring): 43 pseudochromosomes; Track 2: Distribution of gene density with sliding windows of 1 Mb. Higher density is indicated by darker color (the same below). Track 3: Distribution of genes on the forward strand. Track 4: Distribution of genes on the reverse strand. Track 5: Distribution of single nucleotide polymorphism (SNP) density (based on resequencing of 42 shrimps). Track 6: Distribution of simple sequence repeats (SSRs). Track 7: Distribution of GC content (only values between 20% and 50% are displayed). Track 8: Distribution of proportion of repetitive sequences. Track 9: Schematic representation of interchromosomal relationships in the genome.
Figure 2. Comparative genomic analysis of Fenneropenaeus chinensis and homologous species. (a) The distribution of genes in different species. The horizontal axis represents 17 species, and the vertical axis represents the number of genes. (b) Common and unique gene families among four homologous species. (c) Phylogenetic tree of 17 species. Green numbers indicate the number of expanded gene families, and red numbers indicate the number of contracted gene families.
Figure 3. Selective sweeps on the genome of domesticFenneropenaeus chinensis. (a) Conjoint analysis ofF ST and θπ; the red dots indicate the top 5% of rank level values. (b) Results of the KEGG enrichment analysis of the genes under artificial selection pressure in F. chinensis .
