PCIR: a database of Plant Chloroplast Inverted Repeats [PDF]

open access: yesDatabase, 2019
Abstract Inverted repeats (IRs) serve as potential biomarkers for genomic instability, DNA replication and other genetic processes. However, little information can be found in databases to help researchers recognize potential IR nucleotides, explore junction sites and annotate related functional genes. Plant Chloroplast Inverted Repeats (

Bridging PCR: An Efficient and Reliable Scheme Implemented for Genome-Walking

open access: yesCurrent Issues in Molecular Biology, 2023
The efficacy of the available genome-walking methods is restricted by low specificity, high background, or composite operations. We herein conceived bridging PCR, an efficient genome-walking approach.

Recombination-restarted replication makes inverted chromosome fusions at inverted repeats [PDF]

open access: yesNature, 2012
Impediments to DNA replication are known to induce gross chromosomal rearrangements (GCRs) and copy-number variations (CNVs). GCRs and CNVs underlie human genomic disorders and are a feature of cancer. During cancer development, environmental factors and oncogene-driven proliferation promote replication stress.

Conformational and thermodynamic hallmarks of DNA operator site specificity in the copper sensitive operon repressor from Streptomyces lividans [PDF]

open access: yes, 2013
Metal ion homeostasis in bacteria relies on metalloregulatory proteins to upregulate metal resistance genes and enable the organism to preclude metal toxicity.

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

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.

The complete chloroplast genome of Agave fourcroydes

open access: yesMitochondrial DNA. Part B. Resources, 2021
Agave fourcroydes (henequen) is the only cultivated Agave species in the Yucatan Peninsula, which is mainly used for fiber production. In the present study, we have successfully assembled the chloroplast (cp) genome of A. fourcroydes.

Functional Organization of the Inverted Repeats of IS30 [PDF]

open access: yesJournal of Bacteriology, 2010
ABSTRACTThe mobile element IS30has 26-bp imperfect terminal inverted repeats (IRs) that are indispensable for transposition. We have analyzed the effects of IR mutations on both major transposition steps, the circle formation and integration of the abutted ends, characteristic for IS30.

Investigating the DNA-Binding Site for VirB, a Key Transcriptional Regulator of Shigella Virulence Genes, Using an In Vivo Binding Tool [PDF]

open access: yes, 2019
The transcriptional anti-silencing and DNA-binding protein, VirB, is essential for the virulence of Shigella species and, yet, sequences required for VirB-DNA binding are poorly understood.
