Plastid rDNA expression changes with plastic differentiation, plant development and plant growth conditions. Plastid rDNA operons are preceded by different promoter structures that are recognised by different types of RNA polymerase in a species-specific and development-dependent manner. Present knowledge on regulation of rDNA transcription obtained with plant material corresponding to different developmental stages and/or different plant species is summarised. Results indicate the creation of new and unique transcriptional regulatory mechanisms during the evolutionary integration process of the cyanobacterial ancestor into the present-day multi-cellular organism
