Genomic analysis of two Chinese isolates of hyphantria cunea nucleopolyhedrovirus reveals a novel species of alphabaculovirus that infects hyphantria cunea drury (lepidoptera: arctiidae).

ABSTRACT:

Background

Baculoviruses act as effective biological control agents against the invasive pest Hyphantria cunea Drury. In this study, two Chinese Hyphantria cunea nucleopolyhedrovirus (HycuNPV) isolates, HycuNPV-BJ and HycuNPV-HB, were deep sequenced and compared with the Japanese isolate, HycuNPV-N9, to determine whole-genome level diversity and evolutionary history.

Results

The divergence of the phylogenetic tree and the K2P distances based on 38 core-gene concatenated alignment revealed that two Chinese HycuNPV isolates were a novel species of Alphabaculovirus that infected Hyphantria cunea in China. The gene contents indicated significant differences in the HycuNPV genomes between the Chinese and Japanese isolates. The differences included gene deletions, acquisitions and
