Identification of influenza A virus-derived small RNAs. A549 cells were mock treated or infected with influenza A/PR/8/34 H1N1 virus at an MOI of 1. Twelve hours postinfection, total RNA was resolved on an SDS/PAGE gel, and RNA <40 nt in length was isolated and sequenced using SOLiD-based technology. Each of the eight segments (and corresponding accession numbers) and their ORFs are shown. Above each cartoon is a histogram depicting peaks of total reads captured per segment (labeled as n = total reads).
