The characterization and phylogenetic relationship of the trichoplusia ni single capsid nuclear polyhedrosis virus polyhedrin gene.

An EcoRI fragment containing the truncated polyhedrin gene was detected by hybridization with an AcMNPV expression vector probe; the remaining portion of the gene was amplified by reverse PCR. An open reading frame (ORF) of 741 nucleotides (nt), encoding a putative protein of 246 amino acids (a.a) with Mr 28,780 Da was identified. The 50-noncoding region contained the putative late (TAAG) transcription initiation motif. The 30 end, downstream of the translation stop codon, lacked an obvious putative poly (A) signal. Nucleotide and amino acid homology are greater than 80% to that of Mamestra brassicae polyhedrin sequences.Results suggest that T. niSNPV is a member of the group II nuclear polyhedrosis viruses.enThis is the post-print version of the article published available online at http://dx.doi.org/10.1023/A:1008192723971BaculovirusTrichoplusia ni polyhedrin geneSequence analysisPhylogenyArticle
