Fig. 2: Distribution of baculoviral homologs in spider genomes.

a This schematic illustrates the relationship between scaffold length and the number of baculoviral homologs (BHs) in WGS databases of Araneae and SpiderDB (Chr1-Chr13 of T. clavata). The color of the points represented the number of homologs of 22 distinct baculoviral core proteins in scaffolds. b The distribution of BHs in selected spider chromosomes or scaffolds. The lines represent the location of BHs, with the color shades indicating the number of BHs in 1 million base pairs (Mb) window size. The plot is generated using the center positions of BHs via R package ‘CMplot’. c Two representative scaffolds containing host genes and BHs. The detail of nrEVE regions were enlarged above the scaffolds. The GC content and ORF coverage are showed below. The coverage of ORFs was calculated as the total ORFs length compared to the sequence length in 10 kb window sizes. The labels of feature types are displayed below the diagram. Identical repeat regions are shown with arrows of the same color.
