Sequence Analysis of the H/rid m -L Region of the Helicoverpa armigera Single-nudeocapsid Nucleopolyhedrovirus(HaSNPV)
Abstract: In order to investigate the genetic organization of the single nucleocapsid nucleopolyhedrovirus (SNPV) of Helicoverpa armigera (HaSNPV),the Hin d III L fragment of the viral genome was sequenced.The fragment contained five complete open reading frames(ORFs) representing ORF227 (a unique gene),a late expression factor 10 gene ( lef 10),a baculovirus structural protein gene( vp 1 054), Ac 55(a homologue of the AcMNPV ORF55) and Ac 56 (a homologue of the AcMNPV ORF56),respectively.These five genes were identified for the first time in HaSNPV.Alignment of baculovirus LEF10 s indicates that they have conserved leucine zipper regions,and aligament of baculovirus VP1054s indicates that they are highly conserved.
