Ascoviruses 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 29 aros from all sequenced Ascoviridae genomes are divided into six distinct groups. The topological relationship among the isolates of Heliothis 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%.
杆状病毒是感染昆虫的环状双链 DNA 病毒。在此，我们对先前未记录的斜纹夜蛾杆状病毒 3i（HvAV-3i）分离株进行了测序和基因组分析。基因组大小为 185650bp，包含 181 个假定的开放阅读框（ORF）。此外，还基于杆状病毒重复 ORF（aros）提出了定义；即所有已测序的杆状病毒科基因组中的 29 个 aros 分为六个不同的组。(HvAV-3f, {HvAV-3h, [HvAV-3e, (HvAV-3g, HvAV-3i)]})，每个分支都得到了贝叶斯后验概率为 1.00 和 100%的 Bootstrap 值的很好支持。
