Polycistronic mRNA is a mRNA that encodes several proteins and is characteristic of many bacterial and chloroplast mRNAs. Polycistronic mRNAs consist of a leader sequence which precedes the first gene. The gene is followed by an intercistronic region and then another gene. A trailer sequence follows the last gene in the mRNA. Examples of a polycistronic transcripts are found in the chloroplast. One region that exhibits a group of different polycistronic messages from the same region is the psbb/psbH/petB/petD region. The following table lists the genes, their products and the complex of which the product is a part.
