Baculovirus: Molecular Insights on Their Diversity and Conservation

Figure 4

Baculovirus genome phylogeny. Cladogram based on amino acid sequence of core genes. The 31 identified core genes from Baculoviridae family were independently aligned using MEGA 4 [25] program with gap open penalty = 10, gap extension penalty = 1, and dayhoff matrix [26]. Then, a concatemer was generated and phylogeny inferred using the same software (UPGMA; bootstrap with 1000 replicates; gap/missing data = complete deletion; model = amino (dayhoff matrix); patterns among sites = same (homogeneous); rates among sites = different (gamma distributed); gamma parameter = 2.25). Baculoviruses are identified by the acronyms given in Table 1, and the accepted distribution in lineages and genera are also indicated. Gammabaculovirus and Deltabaculovirus are referenced by Greek letters. The proposed clades of Betabaculoviruses are shown in bold letters.
