Sequencing reads and poly(A) sites in viral genes. (A) Landscape of APA sites profiling for viral genes. The track with green color represents the genome annotation from NCBI. The track with red color represents the expressed genes in our analysis. The red points in the center are the sequenced poly(A) sites in the genome and those with black stroke-color represent that their supporting reads are larger than 100. (B) Genomic locations of sequencing reads. The genomic annotation of virus was downloaded from NCBI and the 3′ UTR tail of these genes were annonated as NCBI. (C) Distribution of poly(A) sites in genome. (D) Signal using of poly(A) sites. If none of common hexamers was identified in upstream of poly(A) sites, it was classified into none category.
