A new ascovirus from Spodoptera exigua and its relatedness to the isolate from Spodoptera frugiperda.
A new ascovirus was isolated from Spodoptera exigua in Indonesia and was tentatively assigned as a new species, Spodoptera exigua ascovirus 5a (SeAV-5a) according to the present ICTV ascovirus naming scheme based on DNA restriction fragment length polymorphism (RFLP), hybridization, formation of occlusion body, tissue tropism and host spectrum. SeAV-5a replicated primarily in the fat body of su...
متن کاملPhylogenetic Position and Replication Kinetics of Heliothis virescens Ascovirus 3h (HvAV-3h) Isolated from Spodoptera exigua
Insect-specific ascoviruses with a circular genome are distributed in the USA, France, Australia and Indonesia. Here, we report the first ascovirus isolation from Spodoptera exigua in Hunan, China. DNA-DNA hybridization to published ascoviruses demonstrated that the new China ascovirus isolate is a variant of Heliothis virescens ascovirus 3a (HvAV-3a), thus named HvAV-3h. We investigated the ph...
متن کاملGenomic sequence of Heliothis virescens ascovirus 3g isolated from Spodoptera exigua.
Heliothis virescens ascovirus 3a (HvAV-3a), a member of the family Ascoviridae, has the highest diversity among ascovirus species that have been reported in Australia, Indonesia, China, and the United States. To understand the diversity and origin of this important ascovirus, the complete genome of the HvAV Indonesia strain (HvAV-3g), isolated from Spodoptera exigua, was determined to be 199,72...
متن کاملFunctional and structural characterization of DNMT2 from Spodoptera frugiperda.
Dear Editor, DNA methylation is one of the most important epigenetic marks and plays a central role in gene silencing in high eukaryotes. It is established by DNA methyltransferases (DNMTs), which are classified into three subfamilies. In contrast to DNMT1 and DNMT3, the biological function of DNMT2 remains elusive to date. DNMT2 was first identified in mouse and human and appears to be well co...
