Dimerization and proper degradation of BmNPV IE2 are required for efficient virus growth in larvae of Bombyx mori (Lepidoptera: Bombycidae)

Abstract The baculovirus ie2 gene is one of the immediate early genes, and its product is known to transactivate viral promoters. However, the roles of Bombyx mori nucleopolyhedrovirus (BmNPV) ie2 in insect larvae are poorly understood. Here we investigated the functions of BmNPV IE2 in cultured cel...

520			\|a Abstract The baculovirus ie2 gene is one of the immediate early genes, and its product is known to transactivate viral promoters. However, the roles of Bombyx mori nucleopolyhedrovirus (BmNPV) ie2 in insect larvae are poorly understood. Here we investigated the functions of BmNPV IE2 in cultured cells and in insect larvae using two mutant viruses, BmIE2D and BmIE2CS. BmIE2D lacks the IE2 C-terminal coiled-coil domain that is required for IE2 dimerization. The other mutant BmIE2CS expresses an E3 ligase activity-deficient IE2 derivative, which is degraded more slowly compared with wild-type IE2. We found that ie2 mutations had little effect on BmNPV infection in cultured cells, whereas budded virus and occlusion body production was significantly reduced in the hemolymph of B. mori larvae infected with ie2 mutants. These results indicate that both dimerization and proper degradation of BmNPV IE2 are crucial steps for efficient virus growth in B. mori larvae, but not in cultured cells. Oral infection assays also revealed that the infectivity of the occluded form of ie2 mutants was normal in B. mori larvae, which is inconsistent with the results reported from ie2 mutants of Autographa californica NPV. This suggests that loss of IE2 function causes virus-specific effects in host insects.

However, the roles of Bombyx mori nucleopolyhedrovirus (BmNPV) ie2 in insect larvae are poorly understood. Here we investigated the functions of BmNPV IE2 in cultured cells and in insect larvae using two mutant viruses, BmIE2D and BmIE2CS. BmIE2D lacks the IE2 C-terminal coiled-coil domain that is required for IE2 dimerization. The other mutant BmIE2CS expresses an E3 ligase activity-deficient IE2 derivative, which is degraded more slowly compared with wild-type IE2. We found that ie2 mutations had little effect on BmNPV infection in cultured cells, whereas budded virus and occlusion body production was significantly reduced in the hemolymph of B. mori larvae infected with ie2 mutants. These results indicate that both dimerization and proper degradation of BmNPV IE2 are crucial steps for efficient virus growth in B. mori larvae, but not in cultured cells. Oral infection assays also revealed that the infectivity of the occluded form of ie2 mutants was normal in B. mori larvae, which is inconsistent with the results reported from ie2 mutants of Autographa californica NPV. This suggests that loss of IE2 function causes virus-specific effects in host insects.

However, the roles of Bombyx mori nucleopolyhedrovirus (BmNPV) ie2 in insect larvae are poorly understood. Here we investigated the functions of BmNPV IE2 in cultured cells and in insect larvae using two mutant viruses, BmIE2D and BmIE2CS. BmIE2D lacks the IE2 C-terminal coiled-coil domain that is required for IE2 dimerization. The other mutant BmIE2CS expresses an E3 ligase activity-deficient IE2 derivative, which is degraded more slowly compared with wild-type IE2. We found that ie2 mutations had little effect on BmNPV infection in cultured cells, whereas budded virus and occlusion body production was significantly reduced in the hemolymph of B. mori larvae infected with ie2 mutants. These results indicate that both dimerization and proper degradation of BmNPV IE2 are crucial steps for efficient virus growth in B. mori larvae, but not in cultured cells. Oral infection assays also revealed that the infectivity of the occluded form of ie2 mutants was normal in B. mori larvae, which is inconsistent with the results reported from ie2 mutants of Autographa californica NPV. This suggests that loss of IE2 function causes virus-specific effects in host insects.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Baculovirus</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">IE2</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">BmNPV</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">NPV</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ishihara, Genki</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shimada, Toru</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Katsuma, Susumu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied entomology and zoology</subfield><subfield code="d">Tokyo : Springer, 1966</subfield><subfield code="g">48(2013), 2 vom: 17.

abstract	Abstract The baculovirus ie2 gene is one of the immediate early genes, and its product is known to transactivate viral promoters. However, the roles of Bombyx mori nucleopolyhedrovirus (BmNPV) ie2 in insect larvae are poorly understood. Here we investigated the functions of BmNPV IE2 in cultured cells and in insect larvae using two mutant viruses, BmIE2D and BmIE2CS. BmIE2D lacks the IE2 C-terminal coiled-coil domain that is required for IE2 dimerization. The other mutant BmIE2CS expresses an E3 ligase activity-deficient IE2 derivative, which is degraded more slowly compared with wild-type IE2. We found that ie2 mutations had little effect on BmNPV infection in cultured cells, whereas budded virus and occlusion body production was significantly reduced in the hemolymph of B. mori larvae infected with ie2 mutants. These results indicate that both dimerization and proper degradation of BmNPV IE2 are crucial steps for efficient virus growth in B. mori larvae, but not in cultured cells. Oral infection assays also revealed that the infectivity of the occluded form of ie2 mutants was normal in B. mori larvae, which is inconsistent with the results reported from ie2 mutants of Autographa californica NPV. This suggests that loss of IE2 function causes virus-specific effects in host insects. © The Japanese Society of Applied Entomology and Zoology 2013
