Molecular organization, evolution, and function of ribosomal DNA
Original language description
The aim of this Research Topic is to highlight the current status of knowledge andnresearch on plant ribosomal DNA (rDNA). The Topic compiles seven Original Researchnpapers, five Reviews, one Perspective and one Methods articles, viewed more than 26,000ntimes by the time of this Editorial. The scope covers diverse modern technologies,nscientific approaches, and research aimed at achieving a better understanding of thenmany, complex aspects of rDNA structure, evolution, regulation, and functions in plantndevelopment and adaptation.nThe rDNA encodes four ribosomal RNA (rRNAs), which are the major componentsnof ribosome and constitute 65–75% of the plant cell’s total RNA. Because of itsnabundance, functional importance and specific organization in evolutionarily conservednrRNA coding sequences, and rapidly evolving intergenic spacer (IGS) regions, thenchromosomal and molecular organization, transcription and evolution of the rDNA havenbeen intensively studied since the early days of plant molecular biology.nThe history of rDNA research started almost 90 years ago when McClintock (1934)nobserved that in the interphase nuclei of maize the nucleolus was formed in associationnwith a specific region of a chromosome, which she called the nucleolar organizernregion (NOR). Early rDNA research in plants is presented in article of Hemlebennet al., which covers topics such as the synthesis of rRNA precursors, processing,nthe organization and evolution of 5S and 18S-5.8S-26S (or 35-45S) rDNA as well as epigenetic phenomena and the impact of hybridization andnallopolyploidy on rDNA expression and homogenization. Thisnhistorical view sets the scene for the other articles highlightingnthe progress in modern rDNA research.
