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

BMC 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 ...

Evolution and control of imprinted FWA genes in the genus Arabidopsis. [PDF]

PLoS Genetics, 2008
A central question in genomic imprinting is how a specific sequence is recognized as the target for epigenetic marking. In both mammals and plants, imprinted genes are often associated with tandem repeats and transposon-related sequences, but the role of

Repetitive DNA profile of the amphibian mitogenome

BMC Bioinformatics, 2020
Background Repetitive DNA elements such as direct and inverted repeat sequences are present in every genome, playing numerous biological roles. In amphibians, the functions and effects of the repeat sequences have not been extensively explored.

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 ...

The mitochondrion genome of Heveochlorella roystonensis (Trebouxiophyceae) contains large direct repeats

Mitochondrial DNA. Part B. Resources, 2020
The mitochondrial genome of the epiphytic green alga, Heveochlorella roystonensis was sequenced and characterized. The complete mitogenome contains 130,507 bp, including a single-copy region of 54,865 bp and two direct repeat regions of 37,816 and 37,826

Lycophyte plastid genomics: extreme variation in GC, gene and intron content and multiple inversions between a direct and inverted orientation of the rRNA repeat

New Phytologist, 2019
Summary Lycophytes are a key group for understanding vascular plant evolution. Lycophyte plastomes are highly distinct, indicating a dynamic evolutionary history, but detailed evaluation is hindered by the limited availability of sequences. Eight diverse

The ntrPR Operon of Sinorhizobium meliloti Is Organized and Functions as a Toxin-Antitoxin Module

Molecular Plant-Microbe Interactions, 2006
The chromosomal ntrPR operon of Sinorhizobium meliloti encodes a protein pair that forms a toxin-antitoxin (TA) module, the first characterized functional TA system in Rhizobiaceae. Similarly to other bacterial TA systems, the toxin gene ntrR is preceded
