The genomic characteristics of L. vannamei. a A schematic representation of the genomic characteristics of L. vannamei. Track 1 (from the outer-ring): 44 linkage groups (LGs) of the shrimp genome. Track 2: Scaffolds anchored to each linkage group. Track 3: Protein-coding genes present in the scaffolds. Red represents genes on forward strand and green for genes on reverse strand. Track 4: Distribution of gene density with sliding windows of 1 Mb. Higher density is shown in darker red color. Track 5: Distribution of GC content in the genome. Track 6: Distribution of SNPs density with sliding windows of 5 Mb. Higher density is shown in darker blue color. Track 7: Distribution of six significantly expanded gene families in the genome, which are opsin (O), peritrophin-like protein (P), chitinase (H), calcified cuticle protein (A), crustacyanin (C), and JHE-like carboxylesterase 1 (J). Track 8: Distribution of SSRs in the genome. Higher density of SSRs is shown with deeper color. Track 9: Distribution of miRNA in the genome. Clusters of co-transcribed miRNAs at adjacent positions are displayed in stacked style. Track 10: Schematic presentation of major interchromosomal relationships in the shrimp genome. b SSR content among different animal genomes. c Distribution of different types of SSRs in the L. vannamei genome. d Fluorescence in situ hybridization (FISH) of (AACCT)n type SSR to the nucleus (i) and the chromosomes (ii) of L. vannamei.
