Translational repression by a miniature inverted-repeat transposable element in the 3′ untranslated region

open access: yesNature Communications, 2017
Transposable elements constitute a substantial portion of eukaryotic genomes and contribute to genomic variation, function, and evolution. Miniature inverted-repeat transposable elements (MITEs), as DNA transposons, are widely distributed in plant and ...

Leaping forks at inverted repeats.

open access: yesGenes & development, 2010
Genome rearrangements are often associated with genome instability observed in cancer and other pathological disorders. Different types of repeat elements are common in genomes and are prone to instability. S-phase checkpoints, recombination, and telomere maintenance pathways have been implicated in suppressing chromosome rearrangements, but little is ...

MiteFinderII: a novel tool to identify miniature inverted-repeat transposable elements hidden in eukaryotic genomes

open access: yesBMC Medical Genomics, 2018
Miniature inverted-repeat transposable element (MITE) is a type of class II non-autonomous transposable element playing a crucial role in the process of evolution in biology. There is an urgent need to develop bioinformatics tools to effectively identify

Inverted and mirror repeats in model nucleotide sequences [PDF]

open access: yesPhysical Review E, 2007
We analytically and numerically study the probabilistic properties of inverted and mirror repeats in model sequences of nucleic acids. We consider both perfect and non-perfect repeats, i.e. repeats with mismatches and gaps. The considered sequence models are independent identically distributed (i.i.d.) sequences, Markov processes and long range ...

Complete chloroplast genome of Caragana kozlowii, an alpine shrub endemic to China

open access: yesMitochondrial DNA. Part B. Resources, 2019
Endemic to the southeast boundary of Tibet plateau, the medicinal alpine shrub Caragana kozlowii is a threatened species. The genetic and molecular data about it is insufficient. In this paper, the complete chloroplast (cp) genome sequence of C. kozlowii

Inverted repeat domains in membrane proteins

open access: yesFEBS Letters, 2005
With the upsurge in known membrane protein structures, common structural themes have started to emerge. One of these is the inverted repeat, a tandem of α‐helical domains that have similar tertiary folds but opposite membrane orientations. In all previously known examples, both repeat units were encoded in a single continuous polypeptide.

A cruciform-dumbbell model for inverted dimer formation mediated by inverted repeats [PDF]

open access: yesNucleic Acids Research, 1997
Small inverted repeats (small palindromes) on plasmids have been shown to mediate a recombinational rearrangement event in Escherichia coli leading to the formation of inverted dimers (giant palindromes). This recombinational rearrangement event is efficient and independent of RecA and RecBCD.

The plastid genome sequence of the invasive plant common Ragweed (Ambrosia artemisiifolia, Asteraceae)

open access: yesMitochondrial DNA. Part B. Resources, 2017
In the current study, we present the complete chloroplast genome sequence of Ambrosia artemisiifolia. The genome is 152,223 bp long and consist of 83 protein coding genes, 38 tRNAs, and four rRNAs duplicated in the inverted repeat.

Directed Repeats Co-occur with Few Short-Dispersed Repeats in Plastid Genome of a Spikemoss, Selaginella vardei (Selaginellaceae, Lycopodiopsida)

open access: yesBMC Genomics, 2019
Background It is hypothesized that the highly conserved inverted repeats (IR) structure of land plant plastid genomes (plastomes) is beneficial for stabilizing plastome organization, whereas the mechanism of the occurrence and stability maintenance of ...

Common Repeat Elements in the Mitochondrial and Plastid Genomes of Green Algae

open access: yesFrontiers in Genetics, 2020
Despite both originating from endosymbiotic bacteria, one does not typically expect mitochondrial DNA (mtDNA) to show strong sequence identity to plastid DNA (ptDNA). Nevertheless, a recent analysis of Haematococcus lacustris revealed exactly that.
