Fig 1.

Gene order. Shown are schematic physical maps for the ac53 (A), ac78 (B), and ac101 (C) individual gene clusters. AcMNPV, Lymantria dispar MNPV (LdMNPV), CpGV, NeabNPV, and CuniNPV are the prototypes representing alphabaculoviruses of group I, alphabaculoviruses of group II, betabaculoviruses, gammabaculoviruses, and deltabaculoviruses, respectively. The relative positions and orientations of these three gene clusters are conserved in all baculovirus genomes sequenced to date. The dark arrows represent the newly discovered core genes, the dark gray arrows indicate the previously accepted core genes, and the light gray arrows represent other ORFs described among the core genes illustrated.
