Fig 2. Alignment of PiGV homologous region (hr) palindromic repeats.

Nucleotide positions of the repeats in the genome sequence are indicated. Identical nucleotides occupying >50% of aligned positions are shaded in black, and nucleotides of the same class as conserved nucleotides (containing either a purine or pyrimidine base) are shaded in gray. Nucleotides in the repeat consensus sequence are denoted by uppercase letters for positions in the alignment with completely identical residues, and lowercase letters for positions in the alignment with a majority of identical residues. The conserved 10-bp inverted terminal repeat sequence is indicated by boxes surrounding the aligned sequence at each end.
