Recombination drives vertebrate genome contraction. [PDF]

open access: yesPLoS Genetics, 2012
Selective and/or neutral processes may govern variation in DNA content and, ultimately, genome size. The observation in several organisms of a negative correlation between recombination rate and intron size could be compatible with a neutral model in ...

DNA rearrangements associated with a transposable element in yeast

open access: yesCell, 1980
The his4-912 mutation results from insertion of a 6200 bp transposable element into the his4 gene of yeast. In order to clone the his4-912 mutation, the plasmid pBR322 was integrated into the his4 gene by means of yeast transformation, and then the vector sequences and the his4-912 insertion element were excised as a single restriction fragment.

SoyTEdb: a comprehensive database of transposable elements in the soybean genome

open access: yesBMC Genomics, 2010
Background Transposable elements are the most abundant components of all characterized genomes of higher eukaryotes. It has been documented that these elements not only contribute to the shaping and reshaping of their host genomes, but also play ...

Bioinformatic analysis of Entamoeba histolytica SINE1 elements. [PDF]

open access: yes, 2010
BACKGROUND: Invasive amoebiasis, caused by infection with the human parasite Entamoeba histolytica remains a major cause of morbidity and mortality in some less-developed countries. Genetically E.

DNA methylation enables transposable element-driven genome expansion [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Significance We examined recent whole-genome data of 53 organisms and found that the substantial differences in their genome sizes can be largely explained by the proportion of transposable elements (TEs) within them. TEs coexist with their host largely because CpG methylation suppresses their transcription.

Evolutionary genomics of transposable elements in Saccharomyces cerevisiae

open access: yes, 2012
Saccharomyces cerevisiae is one of the premier model systems for studying the genomics and evolution of transposable elements. The availability of the S.

The CACTA transposon Bot1 played a major role in Brassica genome divergence and gene proliferation [PDF]

open access: yes, 2008
We isolated and characterized a Brassica C genome-specific CACTA element, which was designated Bot1 (Brassica oleracea transposon 1). After analysing phylogenetic relationships, copy numbers and sequence similarity of Bot1 and Bot1 analogues in B ...

The effects of recombination rate on the distribution and abundance of transposable elements

open access: yes, 2008
Transposable elements (TEs) often accumulate in regions of the genome with suppressed recombination. But it is unclear whether this pattern reflects a reduction in the efficacy of selection against deleterious insertions or a relaxation of ectopic ...

Transposable Elements as a Source of Novel Repetitive DNA in the Eukaryote Genome

open access: yesCells, 2022
The impact of transposable elements (TEs) on the evolution of the eukaryote genome has been observed in a number of biological processes, such as the recruitment of the host’s gene expression network or the rearrangement of genome structure. However, TEs may also provide a substrate for the emergence of novel repetitive elements, which contribute to ...

Repetitive DNA is associated with centromeric domains in Trypanosoma brucei but not Trypanosoma cruzi. [PDF]

open access: yes, 2007
BACKGROUND: Trypanosomes are parasitic protozoa that diverged early from the main eukaryotic lineage. Their genomes display several unusual characteristics and, despite completion of the trypanosome genome projects, the location of centromeric DNA has ...
