Fig. 4From: Identification of polycistronic transcriptional units and non-canonical introns in green algal chloroplasts based on long-read RNA sequencing dataTranscriptional characteristics analysis of fragmented genes by RT-PCR, cemA (a), tilS (b), rpoB (c). The positions of primer pairs are shown as arrows with different color. Electrophoresis of PCR products on 1% agarose gel. gDNA (genomic DNA) was used as positive control. S1 and S2 are two different individuals of C. lentillifera. Full-length blots/gels are presented in Supplementary Figure S6Back to article page
