The classical model of concerted evolution states that hundreds to thousands of ribosomal
DNA (rDNA) units undergo homogenization, making the multiple copies of the individual …

Abstract The transcription of 18S, 5.8 S, and 18S rRNA genes (45S rDNA), cotranscriptional
processing of pre-rRNA, and assembly of mature rRNA with ribosomal proteins are the …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Motivation Analyzing k-mer frequencies in whole-genome sequencing data is becoming a
common method for estimating genome size (GS). However, it remains uninvestigated how …

Most diploid organisms have polyploid ancestors. The evolutionary process of
polyploidization is poorly understood but has frequently been conjectured to involve some …

The columbine genus Aquilegia is a classic example of an adaptive radiation, involving a
wide variety of pollinators and habitats. Here we present the genome assembly of A …

The ribosome is an RNA-protein complex that is essential for translation in all domains of
life. The structural and catalytic core of the ribosome is its ribosomal RNA (rRNA). While …

rDNA, the genes encoding the RNA components of ribosomes (rRNA), are highly repetitive
in all eukaryotic genomes, containing 100s to 1000s of copies, to meet the demand for …

During meiosis, DNA double‐strand breaks undergo interhomolog repair to yield crossovers
between homologous chromosomes. To investigate how interhomolog sequence …

Although long-read sequencing can often enable chromosome-level reconstruction of
genomes, it is still unclear how one can routinely obtain gapless assemblies. In the model …
