In most eukaryotes, subtelomeres are dynamic genomic regions populated by multi-copy
sequences of different origins, which can promote segmental duplications and chromosomal …

Chromosomal regions enriched in repetitive DNA sequences have a predisposition to
instability, resulting in a propensity to undergo structural rearrangements. Hence, the rRNA …

The Labeoninae subfamily is a highly diversified but demonstrably monophyletic lineage of
cyprinid fishes comprising five tribes and six incertae sedis genera. This widely distributed …

Cytogenetic studies in Melipona are scarce with only 24 species analyzed cytogenetically.
Of these, six species had the rDNA sites physically mapped and characterized by …

In association with many proteins, small nuclear RNAs (snRNAs) organize the spliceosomes
that play a significant role in processing precursor mRNAs during gene expression …

Abstract Introduction: The Pacific abalone, Haliotis discus hannai, is one of the most
commercially important marine shellfish in China. Cell engineering breeding is an important …

Genes for major ribosomal RNAs (rDNA) are present in multiple copies mainly organized in
tandem arrays. The number and position of rDNA loci can change dynamically and their …

Chromosomal markers of the diversity and evolution of dinoflagellates are scarce because
the genomes of these organisms are unique among eukaryotes in terms of their base …

Simple Summary Fish present astonishing diversity, comprising more species than the
combined total of all other vertebrates. Here, we integrated cytogenetic and genomic data to …

The wide variation found in the size of eukaryotic genomes is largely related to the
accumulation of repetitive sequences. Studies show that these sequences can go through …
