The Dynamic Interplay Between Ribosomal DNA and Transposable Elements: A Perspective From Genomics and Cytogenetics. Mol Biol Evol 2024; 41:msae025.

Abstract
Although both are salient features of genomes, at first glance ribosomal DNAs and transposable elements are genetic elements with not much in common: whereas ribosomal DNAs are mainly viewed as housekeeping genes that uphold all prime genome functions, transposable elements are generally portrayed as selfish and disruptive. These opposing characteristics are also mirrored in other attributes: organization in tandem (ribosomal DNAs) versus organization in a dispersed manner (transposable elements); evolution in a concerted manner (ribosomal DNAs) versus evolution by diversification (transposable elements); and activity that prolongs genomic stability (ribosomal DNAs) versus activity that shortens it (transposable elements). Re-visiting relevant instances in which ribosomal DNA-transposable element interactions have been reported, we note that both repeat types share at least four structural and functional hallmarks: (1) they are repetitive DNAs that shape genomes in evolutionary timescales, (2) they exchange structural motifs and can enter co-evolution processes, (3) they are tightly controlled genomic stress sensors playing key roles in senescence/aging, and (4) they share common epigenetic marks such as DNA methylation and histone modification. Here, we give an overview of the structural, functional, and evolutionary characteristics of both ribosomal DNAs and transposable elements, discuss their roles and interactions, and highlight trends and future directions as we move forward in understanding ribosomal DNA-transposable element associations.

Diversity of short interspersed nuclear elements (SINEs) in lepidopteran insects and evidence of horizontal SINE transfer between baculovirus and lepidopteran hosts. BMC Genomics 2021; 22:226. [PMID: 33789582 PMCID: PMC8010984 DOI: 10.1186/s12864-021-07543-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Accepted: 03/22/2021] [Indexed: 11/16/2022] Open
Abstract
Background Short interspersed nuclear elements (SINEs) belong to non-long terminal repeat (non-LTR) retrotransposons, which can mobilize dependent on the help of counterpart long interspersed nuclear elements (LINEs). Although 234 SINEs have been identified so far, only 23 are from insect species (SINEbase: http://sines.eimb.ru/). Results Here, five SINEs were identified from the genome of Plutella xylostella, among which PxSE1, PxSE2 and PxSE3 were tRNA-derived SINEs, PxSE4 and PxSE5 were 5S RNA-derived SINEs. A total of 18 related SINEs were further identified in 13 lepidopteran insects and a baculovirus. The 3′-tail of PxSE5 shares highly identity with that of LINE retrotransposon, PxLINE1. The analysis of relative age distribution profiles revealed that PxSE1 is a relatively young retrotransposon in the genome of P. xylostella and was generated by recent explosive amplification. Integration pattern analysis showed that SINEs in P. xylostella prefer to insert into or accumulate in introns and regions 5 kb downstream of genes. In particular, the PxSE1-like element, SlNPVSE1, in Spodoptera litura nucleopolyhedrovirus II genome is highly identical to SfSE1 in Spodoptera frugiperda, SlittSE1 in Spodoptera littoralis, and SlituSE1 in Spodoptera litura, suggesting the occurrence of horizontal transfer. Conclusions Lepidopteran insect genomes harbor a diversity of SINEs. The retrotransposition activity and copy number of these SINEs varies considerably between host lineages and SINE lineages. Host-parasite interactions facilitate the horizontal transfer of SINE between baculovirus and its lepidopteran hosts.

The Ribosome as a Missing Link in Prebiotic Evolution III: Over-Representation of tRNA- and rRNA-Like Sequences and Plieofunctionality of Ribosome-Related Molecules Argues for the Evolution of Primitive Genomes from Ribosomal RNA Modules. Int J Mol Sci 2019; 20:ijms20010140. [PMID: 30609737 PMCID: PMC6337102 DOI: 10.3390/ijms20010140] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Revised: 12/21/2018] [Accepted: 12/23/2018] [Indexed: 12/18/2022] Open
Abstract
We propose that ribosomal RNA (rRNA) formed the basis of the first cellular genomes, and provide evidence from a review of relevant literature and proteonomic tests. We have proposed previously that the ribosome may represent the vestige of the first self-replicating entity in which rRNAs also functioned as genes that were transcribed into functional messenger RNAs (mRNAs) encoding ribosomal proteins. rRNAs also encoded polymerases to replicate itself and a full complement of the transfer RNAs (tRNAs) required to translate its genes. We explore here a further prediction of our “ribosome-first” theory: the ribosomal genome provided the basis for the first cellular genomes. Modern genomes should therefore contain an unexpectedly large percentage of tRNA- and rRNA-like modules derived from both sense and antisense reading frames, and these should encode non-ribosomal proteins, as well as ribosomal ones with key cell functions. Ribosomal proteins should also have been co-opted by cellular evolution to play extra-ribosomal functions. We review existing literature supporting these predictions. We provide additional, new data demonstrating that rRNA-like sequences occur at significantly higher frequencies than predicted on the basis of mRNA duplications or randomized RNA sequences. These data support our “ribosome-first” theory of cellular evolution.

Abstract
Short interspersed elements (SINEs), which are nonautonomous transposable elements, require the transposition machinery of long interspersed elements (LINEs) to mobilize. SINEs are composed of two or more independently originating parts. The 5′ region is called the “head” and is derived mainly from small RNAs, and the 3′ region (“tail”) originates from the 3′ region of LINEs and is responsible for being recognized by counterpart LINE proteins. The origin of the middle “body” of SINEs is enigmatic, although significant sequence similarities among SINEs from very diverse species have been observed. Here, a systematic analysis of the similarities among SINEs and LINEs deposited on Repbase, a comprehensive database of eukaryotic repeat sequences was performed. Three primary findings are described: 1) The 5′ regions of only two clades of LINEs, RTE and Vingi, were revealed to have contributed to the middle parts of SINEs; 2) The linkage of the 5′ and 3′ parts of LINEs can be lost due to occasional tail exchange of SINEs; and 3) The previously proposed Ceph-domain was revealed to be a fusion of a CORE-domain and a 5′ part of RTE clade of LINE. Based on these findings, a hypothesis that the 5′ parts of bipartite nonautonomous LINEs, which possess only the 5′ and 3′ regions of the original LINEs, can contribute to the undefined middle part of SINEs is proposed.

Abstract
Polymorphisms in regions upstream of transcription initiation site may modify the transcriptional activity of target genes by changing promoter activity. This study aims to determine whether or not polymorphisms at porcine IGFBP7 promoter region affect gene expression. In this study, eight SNPs and one PRE1 insertion in this region were first confirmed. The PRE1 insertion was widespread in 20 Chinese indigenous breeds, but was not observed in three commercial breeds. A perfect linkage disequilibrium, consisting of six of those SNPs and a PRE1, was observed with two haplotypes (h1 and h2) in five pig breeds. The h1 haplotype had an overwhelming superiority distribution in Large White, Landrace, and Bama mini-pig; in turn, the h2 only existed in the PRE1 presence breeds. As the haplotypes and PRE1 were located at gene promoter regions, we further investigated the transfection of plasmids with three different fragments of IGFBP-7 promoter region (H1, H2, RF). The CMV promoter of the pEGFP-N1 was substituted by these three different fragments, respectively. Different transcriptional and translational activities of EGFP in PK-15 cells were observed in these three recombinant plasmids by quantitative real-time PCR and flow cytometric analysis. The results indicated that H1 had the higher transcriptional and translational activities of EGFP as compared to the H2 (P < 0.05, P < 0.05). As compared to the RF group, EGFP mRNA expression level was significantly higher in H1 groups (P < 0.05). The IGFBP-7 promoter polymorphisms detected in this study may be important functional variants and potential genetic markers for pig population genetic study.

Abstract
Human centromeres are defined by alpha satellite DNA arrays that are distinct and chromosome specific. Most human chromosomes contain multiple alpha satellite arrays that are competent for centromere assembly. Here, we show that human centromeres are defined by chromosome-specific RNAs linked to underlying organization of distinct alpha satellite arrays. Active and inactive arrays on the same chromosome produce discrete sets of transcripts in cis. Non-coding RNAs produced from active arrays are complexed with CENP-A and CENP-C, while inactive-array transcripts associate with CENP-B and are generally less stable. Loss of CENP-A does not affect transcript abundance or stability. However, depletion of array-specific RNAs reduces CENP-A and CENP-C at the targeted centromere via faulty CENP-A loading, arresting cells before mitosis. This work shows that each human alpha satellite array produces a unique set of non-coding transcripts, and RNAs present at active centromeres are necessary for kinetochore assembly and cell-cycle progression.

Abstract
Parasite host switches may trigger disease emergence, but prehistoric host ranges are often unknowable. Lymphatic filariasis and loiasis are major human diseases caused by the insect-borne filarial nematodes Brugia, Wuchereria and Loa. Here we show that the genomes of these nematodes and seven tropical bird lineages exclusively share a novel retrotransposon, AviRTE, resulting from horizontal transfer (HT). AviRTE subfamilies exhibit 83–99% nucleotide identity between genomes, and their phylogenetic distribution, paleobiogeography and invasion times suggest that HTs involved filarial nematodes. The HTs between bird and nematode genomes took place in two pantropical waves, >25–22 million years ago (Myr ago) involving the Brugia/Wuchereria lineage and >20–17 Myr ago involving the Loa lineage. Contrary to the expectation from the mammal-dominated host range of filarial nematodes, we hypothesize that these major human pathogens may have independently evolved from bird endoparasites that formerly infected the global breadth of avian biodiversity. Lymphatic filariasis and loiasis are diseases caused by insect-borne filarial nematodes. Here, Suh et al. identify a retrotransposon that is present in the genomes of these nematodes and seven tropical bird lineages, indicating two waves of horizontal gene transfer around 17–25 million years ago.

Abstract
SINEs (Short INterspersed Elements) are widely distributed among eukaryotes. Some SINE families are organized in superfamilies characterized by a shared central domain. These central domains are conserved across species, classes, and even phyla. Here we report the identification of two novel such superfamilies in the genomes of gastropod and bivalve mollusks. The central conserved domain of the first superfamily is present in SINEs in Caenogastropoda and Vetigastropoda as well as in all four subclasses of Bivalvia. We designated the domain MESC (Romanian for MElc-snail and SCoica-mussel) because it appears to be restricted to snails and mussels. The second superfamily is restricted to Caenogastropoda. Its central conserved domain-Snail-is related to the Nin-DC domain. Furthermore, we provide evidence that a 40-bp subdomain of the SINE V-domain is conserved in SINEs in mollusks and arthropods. It is predicted to form a stable stem-loop structure that is preserved in the context of the overall SINE RNA secondary structure in invertebrates. Our analysis also recovered short retrotransposons with a Long INterspersed Element (LINE)-derived 5' end. These share the body and/or the tail with transfer RNA (tRNA)-derived SINEs within and across species. Finally, we identified CORE SINEs in gastropods and bivalves-extending the distribution range of this superfamily.
