Discovering the Repeatome of Five Species Belonging to the Asteraceae Family: A Computational Study

open access: yesPlants, 2023
Genome divergence by repeat proliferation and/or loss is a process that plays a crucial role in species evolution. Nevertheless, knowledge of the variability related to repeat proliferation among species of the same family is still limited.

Terminally repeated sequences in the avian sarcoma virus RNA genome. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1977
The initiation of DNA synthesis in vitro by RNA-directed DNA polymerase (deoxynucleosidetriphosphate: DNA deoxynucleotidyltransferase, EC 2.7.7.7) of avian oncornaviruses requires a tRNAtrp primer molecule located close to the 5' end of the viral RNA genome.

High-throughput nanopore sequencing of Treponema pallidum tandem repeat genes arp and tp0470 reveals clade-specific patterns and recapitulates global whole genome phylogeny

open access: yesFrontiers in Microbiology, 2022
Sequencing of most Treponema pallidum genomes excludes repeat regions in tp0470 and the tp0433 gene, encoding the acidic repeat protein (arp). As a first step to understanding the evolution and function of these genes and the proteins they encode, we ...

Nucleotide sequences of the retroviral long terminal repeats and their adjacent regions [PDF]

open access: yesNucleic Acids Research, 1984
The nucleotide sequences of the LTRs and their adjacent regions from 19 type C and one type B retrovirus were compared. Salient features are: (a) The R regions in the genomes of most of the type C retroviruses begin with GC and end with CA. (b) The mammalian type C retroviruses have a polyadenylation signal "AATAAA" in the R region, and most have a ...

Nucleotide sequence analysis of the long terminal repeat of integrated simian sarcoma virus: evolutionary relationship with other mammalian retroviral long terminal repeats [PDF]

open access: yesJournal of Virology, 1982
Nucleotide sequence analysis of the long terminal repeat (LTR) of the integrated simian sarcoma virus showed that the simian sarcoma virus LTR comprised 504 nucleotides with an inverted repeat of seven bases at its 5' and 3' termini. At the site of simian sarcoma virus integration, cellular flanking sequences adjacent to the proviral LTR contained a ...

Genetic polymorphism and natural selection of circumsporozoite protein in Myanmar Plasmodium vivax

open access: yesMalaria Journal, 2020
Background Circumsporozoite surface protein (CSP) of malaria parasites has been recognized as one of the leading vaccine candidates. Clinical trials of vaccines for vivax malaria incorporating Plasmodium vivax CSP (PvCSP) have demonstrated their ...

Genetic Diversity, Repeat Motifs, and Natural Selection at the C-Terminal Knob-Associated Histidine Rich Protein (KAHRP) of Plasmodium falciparum Clinical Samples from Saudi Arabia

open access: yesJournal of Tropical Medicine, 2022
Background. Malaria is still a public health problem in Saudi Arabia specifically in the Jazan region. Plasmodium falciparum knob-associated histidine-rich proteins (PfKAHRPs) play an important role in cerebral malaria pathophysiology as well as ...

Replication of the retroviral terminal repeat sequence during in vivo reverse transcription [PDF]

open access: yesJournal of Virology, 1993
There is a copy of a short terminal repeat segment, r, at each end of the retroviral RNA genome. During reverse transcription, r is copied from the genomic RNA to form the R component of the long terminal repeat in viral DNA. Although our current model for reverse transcription suggests that the 5' r is copied, it is not known whether the 5' copy, the ...

Human transposable elements in Repbase: genomic footprints from fish to humans

open access: yesMobile DNA, 2018
Repbase is a comprehensive database of eukaryotic transposable elements (TEs) and repeat sequences, containing over 1300 human repeat sequences. Recent analyses of these repeat sequences have accumulated evidences for their contribution to human ...

Comparative Next-Generation Sequencing of Adeno-Associated Virus Inverted Terminal Repeats

open access: yesBioTechniques, 2014
The inverted terminal repeats (ITRs) of adeno-associated virus (AAV) are notoriously difficult to sequence owing to their high GC-content (70%) and palindromic sequences that result in the formation of a very stable, 125 bp long, T-shaped hairpin structure. Here we evaluate the performance of two widely used next-generation sequencing platforms, 454 GS
