Fig. S1. SDS-PAGE analysis of overexpressed and purified ORF3. Lane 1, molecular markers; lane 2, purified ORF3. The arrowhead indicates the band of ORF3 protein. [PDF] (79 kb)
Fig. S2. Transcriptional analysis of EcOYM-encoded genes. RT-PCR analysis of EcOYM-encoded genes (orf1-5) was performed using total RNA isolated from OY-M-infected insects. The lengths of orf1-4 are 486, 603, 465 and 315 bp, respectively. The full-length of orf5 is 1305 bp, but only a partial region was amplified. To prove an absence of DNA contamination in the total RNA, PCR analysis of the OY-M amp gene was performed without reverse transcription (negative control). [PDF] (84 kb)
Fig. S3. Complete set of EcOY-DNAs and pOY plasmids from OY lines. orf3 is encoded on EcOYNIM but not on pOYNIM. The major promoter of orf3 (ORF3-pro2) is indicated by the open arrows on EcOYW and EcOYM, but it is not encoded on EcOYNIM. [PDF] (88 kb)
