Long-read sequencing reveals atypical mitochondrial genome structure in a New Zealand marine isopod

Royal Society Open Science, 2022
Most animal mitochondrial genomes are small, circular and structurally conserved. However, recent work indicates that diverse taxa possess unusual mitochondrial genomes.

Comparative genomics study of inverted repeats in bacteria [PDF]

Bioinformatics, 2002
Abstract Motivation: Comparative genomics provides a powerful way to investigate regularities and differences observed at DNA level across species. Here we study the number and location of inverted repeats occurring in complete genomes of bacteria.

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

Current 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.

The complete chloroplast genome of Agave fourcroydes

Mitochondrial 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.

Data‐driven performance metrics for neural network learning

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

MUSTv2: An Improved De Novo Detection Program for Recently Active Miniature Inverted Repeat Transposable Elements (MITEs)

Journal of Integrative Bioinformatics, 2017
Miniature inverted repeat transposable element (MITE) is a short transposable element, carrying no protein-coding regions. However, its high proliferation rate and sequence-specific insertion preference renders it as a good genetic tool for both natural ...

Long-reads reveal that Rhododendron delavayi plastid genome contains extensive repeat sequences, and recombination exists among plastid genomes of photosynthetic Ericaceae [PDF]

PeerJ, 2020
Background Rhododendron delavayi Franch. var. delavayi is a wild ornamental plant species in Guizhou Province, China. The lack of its plastid genome information seriously hinders the further application and conservation of the valuable resource.

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

Database, 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 (

Full-length chloroplast genome of Dongxiang wild rice reveals small single-copy region switching

Frontiers in Plant Science, 2022
BackgroundPlant chloroplast DNA (cpDNA) typically has a circular structure, including a large single-copy region (LSC), a small single-copy region (SSC) and two inverted repeats (IR1 and IR2). The organization of these four elementary regions LSC-IR1-SSC-

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

Nucleic 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.
