FIG. 6.

Detection of the caroDK/caroDI transcripts by RT-PCR. (A) Schematic representation of the RT-PCR experiment. The small arrows indicate the positions and directions of the gene-specific primers used in RT-PCR with lengths of the expected PCR product, and the wavy arrow indicates transcription. (B) Agarose gel electrophoresis of RT-PCR products. The reactions were carried out in the presence of a reverse transcriptase (cDNA) or with the genomic DNA as a template (DNA). DK indicates the caroDK gene-specific product, DI indicates the caroDI-specific product, and DKI indicates the caroDK and caroDI product.
