Genomic analysis of a novel isolate Heliothis virescens ascovirus 3i (HvAV-3i) and identification of ascoviral repeat ORFs ( aro s)

AbstractAscoviruses are circular double-stranded DNA viruses that infect insects. Herein we sequenced and analyzed the genome of the previously unrecorded ascovirus isolate Heliothis virescens ascovirus 3i (HvAV-3i). The genome size is 185,650  bp with 181 hypothetical open reading frames (ORFs). Additionally, definition based on ascovirus repeated ORFs (aros) is proposed; whereby the 29aros from all sequencedAscoviridae genomes are divided into six distinct groups. The topological relationship among the isolates ofHeliothis virescens ascovirus 3a is (HvAV-3f, {HvAV-3h, [HvAV-3e, (HvAV-3g, HvAV-3i)]}) with every clade well supported by a Bayesian posterior probability of 1.00 and a Bootstrap value of 100%.
