“…For example, in the plant Plantago lagopus , PLsatB satDNA includes sequence parts which correspond with 5SrRNA and NTS fragments [ 29 ]. A similar process probably produced PcP190 satDNA in frogs, which is derived from the 5S rDNA and NTS [ 5 ]. In contrast to these examples, in T. freemani NTS sequences themselves show satDNA features forming tandemly arranged arrays in 5S rRNA clusters.…”

“…For example, single copies of the 5S rDNA are found inserted into 45S rDNA intergenic spacers in the genomes of some fishes [ 4 ]. Several studies on the organization and molecular evolution of 5S rDNA have reported association of 5S rRNA genes with satellite DNAs (satDNAs) [ 5 , 6 ]. SatDNAs are the most abundant and rapidly evolving noncoding DNAs of all eukaryotic genomes.…”

5S ribosomal DNAs (rDNAs) are arranged in tandem and are often under-represented in genome assemblies. In the present study, we performed a global and in-depth analysis of the 5S rDNAs in the model insect Tribolium castaneum and its closely related species Tribolium freemani. To accomplish this goal, we used our recently published genome assemblies based on Nanopore and PacBio long-read sequencing. Although these closely related species share the 5S rRNA gene sequence with high homology, they show a different organization of the 5S rDNA locus. Analysis of 5S rDNA arrays in T. castaneum revealed a typical tandemly repeated organization characterized by repeat units consisting of the 121 bp long 5S rRNA gene and the 71 bp long nontranscribed spacer (NTS). In contrast, T. freemani showed a much more complex organization of 5S rDNA arrays characterized by two patterns. The first is based on the association of 5S rRNA gene with arrays of a satellite DNA, representing the NTS sequence of the 5S rDNA genes in T. freemani. The second, more complex type is characterized by a somewhat less frequent occurrence of the 5S rRNA gene and its association with longer satellite DNA arrays that are regularly interrupted by Jockey-like retrotransposons. This organization, in which the ribosomal gene is associated with two completely different repetitive elements such as satellite DNAs and retrotransposons, suggests that the 5S rRNA gene, regardless of its crucial function in the genome, could be a subject of extremely dynamic genomic rearrangements.

“…Because of this recombination suppression, chromosome Y or W may undergo degeneration, which involves the loss of genes and the accumulation of repetitive DNA, leading to highly heteromorphic sex chromosomes (Charlesworth et al, 2005;Ellegren, 2011;Schartl et al, 2016). Among anurans, only 52 (review in Targueta et al, 2018;Ferro et al, 2018;Gazoni et al, 2018) of the karyotyped species show heteromorphic sex chromosomes, while most species possess homomorphic sex chromosomes, which are not differentiated by classical cytogenetic techniques. In this order of amphibians, an interesting case is observed in the genus Pseudis, in which species with different levels of sex chromosome differentiation are present.…”

“…Em anuros a ocorrência de cromossomos sexuais heteromórficos é limitada, sendo que apenas 52 das espécies de anuros já estudadas citogeneticamente possuem cromossomos sexuais heteromórficos, enquanto a maioria das espécies apresenta cromossomos sexuais homomórficos (revisão em Targueta et al, 2018;Gazoni et al, 2018;Ferro et al, 2018). A prevalência de cromossomos sexuais homomórficos pode ser explicada por uma alta taxa de transição entre sistemas de determinação de sexo que não permitiria a ocorrência da degeneração do cromossomo Y/W e o estabelecimento de cromossomos sexuais heteromórficos (Evans et al, 2012).…”
