Sunflower centromeres consist of a centromere-specific LINE and a chromosome-specific tandem repeat

Frontiers in Plant Science, 2015
The kinetochore is a protein complex including kinetochore-specific proteins that plays a role in chromatid segregation during mitosis and meiosis. The complex associates with centromeric DNA sequences that are usually species-specific. In plant species,

Comprehensive In Silico Analysis of Retrotransposon Insertions within the Survival Motor Neuron Genes Involved in Spinal Muscular Atrophy

Biology, 2022
Transposable elements (TEs) are interspersed repetitive and mobile DNA sequences within the genome. Better tools for evaluating TE-derived sequences have provided insights into the contribution of TEs to human development and disease.

A Test of the Master Gene Hypothesis for Interspersed Repetitive DNA Sequences [PDF]

Molecular Biology and Evolution, 2005
Many families of interspersed repetitive DNA elements, including human Alu and LINE (Long Interspersed Element) elements, have been proposed to have accumulated through repeated copying from a single source locus: the "master gene." The extent to which a master gene model is applicable has implications for the origin, evolution, and function of such ...

Methylation levels of the "long interspersed nucleotide element-1" repetitive sequences predict survival of melanoma patients

Journal of Translational Medicine, 2011
Background The prognosis of cutaneous melanoma (CM) differs for patients with identical clinico-pathological stage, and no molecular markers discriminating the prognosis of stage III individuals have been established.

Higher Alu methylation levels in catch-up growth in twenty-year-old offsprings. [PDF]

PLoS ONE, 2015
Alu elements and long interspersed element-1 (LINE-1 or L1) are two major human intersperse repetitive sequences. Lower Alu methylation, but not LINE-1, has been observed in blood cells of people in old age, and in menopausal women having lower bone mass

Survey sequencing and comparative analysis of the elephant shark (Callorhinchus milii) genome.

PLoS Biology, 2007
Owing to their phylogenetic position, cartilaginous fishes (sharks, rays, skates, and chimaeras) provide a critical reference for our understanding of vertebrate genome evolution.

Complete mitochondrial genome of the endangered Prunus pedunculata (Prunoideae, Rosaceae) in China: characterization and phylogenetic analysis

Frontiers in Plant Science, 2023
IntroductionPrunus pedunculata (Prunoideae: Rosaceae), a relic shrub with strong resistance and multiple application values, is endangered in China. Extensive research had been devoted to gene expression, molecular markers, plastid genome analysis, and ...

The distribution of interspersed repetitive DNA sequences in the human genome

Genomics, 1989
The distribution of interspersed repetitive DNA sequences in the human genome has been investigated, using a combination of biochemical, cytological, computational, and recombinant DNA approaches. "Low-resolution" biochemical experiments indicate that the general distribution of repetitive sequences in human DNA can be adequately described by models ...

YAC subclone contig assembly by serial interspersed repetitive sequence (IRS)-PCR product hybridizations [PDF]

Nucleic Acids Research, 1993
Yeast artificial chromosomes (YACs) are presently the most effective means of cloning large contiguous regions of genomic DNA (1). However, performing a detailed molecular analysis of YAC clone insert DNA is constrained by inherent physical and technical limitations. Typically, an extended analysis of YAC DNA is facilitated by subcloning YAC insert DNA

Dynamics of tandemly repeated DNA sequences during evolution of diploid and tetraploid botiid loaches (Teleostei: Cobitoidea: Botiidae). [PDF]

PLoS ONE, 2018
Polyploidization has played an important role in the evolution of vertebrates, particularly at the base of Teleostei-an enormously successful ray-finned fish group with additional genome doublings on lower taxonomic levels.
