Genomic architecture of 5S rDNA cluster and its variations within and between species [PDF]
BMC Genomics, 2022 Background Ribosomal DNAs (rDNAs) are arranged in purely tandem repeats, preventing them from being reliably assembled onto chromosomes during generation of genome assembly.

Ancient Origin of Two 5S rDNA Families Dominating in the Genus Rosa and Their Behavior in the Canina-Type Meiosis [PDF]
Frontiers in Plant Science, 2021 The genus Rosa comprises more than 100 woody species characterized by intensive hybridization, introgression, and an overall complex evolutionary history. Besides many diploid species (2n = 2x = 14) polyploids ranging from 3x to 10x are frequently found.

Contrasting patterns of 5S rDNA repeats in European and Asian ecotypes of greater duckweed, Spirodela polyrhiza (Lemnaceae) [PDF]
Frontiers in Plant ScienceRibosomal DNA (rDNA) contains highly conserved, specifically organized sequences encoding ribosomal RNAs (rRNAs) separated by variable non-transcribed intergenic spacers (NTSs) and is abundant in eukaryotic genomes. These characteristics make the rDNA an

Genome sequence assembly of the 5S rDNA loci informs haplotype specificity and evolution in the greater duckweed Spirodela polyrhiza [PDF]
Communications BiologyDespite the rapid expansion of information on eukaryotic genomes, data on ribosomal DNA (rDNA) loci encoding ribosomal RNAs, crucial for the biogenesis of ribosomes, are absent in almost all cases due to difficulties in assembling the long regions of ...
