FIG. 1.

Genome organization of FBNSV. The eight viral DNAs are grouped according to their phylogenetic relationships. Branch lengths are drawn to scale with base substitutions per nucleotide as units, and branch support is shown by bootstrap values (500 replicates). Inside each circle the name of the genomic DNA is given, indicating the respective encoded proteins. M-Rep, master replication initiator protein; CP, capsid protein; Clink, cell cycle link protein; MP, movement protein; NSP, nuclear shuttle protein; U1, U2, and U4, proteins of as-yet-unknown function; CR-I, common region I (inverted repeat sequences flanking the replication origin are symbolized by a knob); CR-II, second common region. Other highly similar sequences (common regions) in DNAs are denoted as CR- followed by the name of the respective genomic DNA.
