genome sequence and organization analysis of heliothis virescens ascovirus 3f isolated from a helicoverpa zea larva. | the complete genome sequence of heliothis virescens ascovirus 3f (hvav-3f) was obtained. the hvav-3f genome has a circular genome of 198,157bp with a g+c content of 46.0%, and encodes 190 open reading frames (orfs) longer than 69 amino acids. two major homologous regions (hrs) and 29 'baculovirus repeat orfs' (bro) were found in the genome. blast analyses revealed that three hvav-3f genes were homologous to that of lepidopteran insects. nine orfs were unique to hvav-3f, in which two orfs showed ... | 2014 | 25149038 |
