Viruses interact with nearly all organisms on Earth, thereby influencing biogeochemical cycles, agriculture, and health. However, less is known about the composition and function of viruses in agricultural rhizosphere soils, especially under consecutive monoculture regimes. Our qRT-PCR analysis in this study showed that consecutive monoculture regi...

Nucleopolyhedrovirus (NPV) can alter its host behaviour such that infected larvae hang at the top of trees before their death. This phenomenon was firstly described by Hofmann in 1891 and named as “tree-top disease”. Subsequent studies have described effects during the infection proceedings as NPVs manipulate the host to avoid the immune response,...
