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 .
