An abridged ORF list with additional constraints.

The ORFs in Table 1 were screened with additional filters, strong Kozak consensus sequence, upstream AUG location (within the first third of the transcript), and high prevalence (≥95% and ≥50% for in-frame and alternative-frame ORFs, respectively), to obtain 16 novel ORFs. These ORFs were named, according to conventions, as PB1-N40, PA-N155, PA-N182 (in-frame) and PB1-F2 (alternative-frame). The 4 known ORFs are excluded from this table.An abridged ORF list with additional constraints.
