The Bombyx mori nucleopolyhedrovirus (BmNPV) La is a variant BmNPV strain isolated in Laos. La has different features from BmNPV type strain T3 in virulence, production of the polyhedrin protein, and the formation of multicapsid occlusion-derived viruses. Here, the whole-genome sequence of La was compared to the sequences of nine BmNPV and two Bombyx mandarina nucleopolyhedrovirus strains. The complete La genome consisted of 127,618 base pairs with a G + C content of 40.3% and contained putative 136 open reading frames encoding more than 60 amino acids. The La genome lacked the bro-b gene and had the highest identity with that of the T3 strain. A comparison of the transcriptomes of La- and T3-infected cells showed that the expression levels of the polyhedrin and cathepsin genes were greater in cells infected with La as compared to those infected with T3. Interestingly, the virus genes with different RNA levels between the two BmNPV strains were assembled into five clusters in the genome of La. Also, the RNA levels of host ribosomal protein genes were significantly decreased in cells infected with La as compared to those infected with T3.
