Fig. 4

Similarities between WSSV-like genes in the crab and shrimp genomic libraries visualized as a hive-plot. The three axes correspond to 1) genes from WSSV with a reported function (Leu et al., 2009) and/or homology to sequences from the decapod libraries; 2) homologs of WSSV-genes from the Metopaulias library and 3) homologs of WSSV-genes identified in the repetitive sequences from Penaeus monodon (Huang et al., 2011) and P. japonicus (Koyama et al., 2010). Genes on the axes are arranged in the order on the WSSV-CH genome. Lines connecting homologs are colored according to amino acid similarities (see Additional file 3). When multiple alignments were available for the same gene only one was chosen. In cases of multiple paralogs in the penaeid shrimp libraries only one representative was taken with the preference given to proteins from P. japonicus
