During evolution of photosynthetic organisms, the genetic information provided by the internalized cyanobacteria has been transferred to the nucleus. The small genome kept by the chloroplast, the so-called plastome, displays a complex organization, comprising operons under the control of multiples promoters. In addition, polycistronic transcripts undergo multiple processing events, thus generating a complex population of mRNAs from a single gene. This chapter describes a method to investigate the diversity of the mRNA population from a single gene by circular RT-PCR. The protocol provided here allows for the simultaneous mapping of both 5′ and 3′ ends of the same RNA molecule.
