Genome sequence and organization of the Mythimna (formerly Pseudaletia) unipuncta granulovirus Hawaiian strain.

ABSTRACT: Purified occlusion bodies (OBs) of Mythimna (formerly Pseudaletia) unipuncta (the true armyworm) granulovirus Hawaiian strain (MyunGV-A) were observed, showing typical GV morphological characteristics under scanning and transmission electron microscopy (EM). The genome of MyunGV-A was completely sequenced and analysed. The genome is 176,677 bp in size, with a G+C content of 39.79%. It contains 183 open reading frames (ORFs) encoding 50 or more amino acids with minimal overlap. Comparison of MyunGV-A with TnGV, XcGV, and HearGV genomes revealed extensive sequence similarity and collinearity, and the four genomes contain the same nine homologous regions (hrs) with conserved structures and locations. Three unique genes, 12 baculovirus repeated ORF (bro), 2 helicase, and 3 enhancin genes, were
