title: Transcription of the chloroplast DNA: a review.
abstract: The transcription systems of chloroplasts and bacteria share different properties. The genetic material of chloroplasts is organized in the same way as bacterial nucleoids. The regulatory DNA sequences for transcription have a strong homology with their E. coli counterparts and some regulatory mechanisms could be conserved. The RNA polymerase subunits and some transcription factors also share similarities with prokaryotes. However, the chloroplast core-enzyme seems to be synthesized in the cytoplasm from nuclear encoded messages.
