Fig. 5From: Genome-wide identification of circular RNAs in peanut (Arachis hypogaea L.)Validation of circRNAs by qRT-PCR and Sanger sequencing. a The expected fragments amplified with divergent primers (covering the back-splicing junction) in 15 circRNAs. b circRNA604 was further confirmed by Sanger sequencing. The red arrow represents the back-splicing site of circRNA604Back to article page
