Figure 2. Comparison of mRNA sequences of bat coronavirus (BatCoV) with viral genomic sequences. Read 1 was obtained by using reverse transcription–PCR and HKU9-Leader42–64 and N468–448r primers. Read 2 was obtained by using HKU9-Leader42–64 and Ns7a440–420r primers. Asterisks indicate sequence identity for read and virus genome sequences. TRS, transcription regulatory sequence; N, nucleocapsid; NS, nonstructural.
