Fig. 4From: Pervasive read-through transcription of T-DNAs is frequent in tobacco BY-2 cells and can effectively induce silencingTranscription analysis of selected BY-2 calli transformed with pER8-IR-PIN3. RT-qPCR analysis of transcript levels in eleven randomly selected calli and an untransformed BY-2 callus as a control. a The level of the PIN3 mRNA (RT: oligo dT primer, qPCR: PIN3_F and PIN3_R primers); b the level of the sense intron of the IR-PIN3 (representing both the unspliced transcript and the spliced intron; RT: R5 primer, qPCR: F5 and R5 primers)Back to article page
