Rearrangement of Noisy Genomes [PDF]

, 2006
Measures of distance between genomic maps are inflated by high levels of noise due to incorrectly resolved paralogy and error at the mapping, sequencing and alignment levels. Comparison is also hampered by lack of information on gene orientation and lack gene order.

Combinatorics of Genome Rearrangements [PDF]

, 2009
A comprehensive survey of a rapidly expanding field of combinatorial optimization, mathematically oriented but offering biological explanations when required. From one cell to another, from one individual to another, and from one species to another, the content of DNA molecules is often similar.

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

, 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 ...

Genome dedoubling by DCJ and reversal

BMC Bioinformatics, 2011
Background Segmental duplications in genomes have been studied for many years. Recently, several studies have highlighted a biological phenomenon called breakpoint-duplication that apparently associates a significant proportion of segmental duplications ...

Programmed genome rearrangements in ciliates [PDF]

Cellular and Molecular Life Sciences, 2020
AbstractCiliates are a highly divergent group of unicellular eukaryotes with separate somatic and germline genomes found in distinct dimorphic nuclei. This characteristic feature is tightly linked to extremely laborious developmentally regulated genome rearrangements in the development of a new somatic genome/nuclei following sex.

Recovery of a medieval Brucella melitensis genome using shotgun metagenomics [PDF]

, 2014
Shotgun metagenomics provides a powerful assumption-free approach to the recovery of pathogen genomes from contemporary and historical material. We sequenced the metagenome of a calcified nodule from the skeleton of a 14th-century middle-aged male ...

Negative Regulators of an RNAi-Heterochromatin Positive Feedback Loop Safeguard Somatic Genome Integrity in Tetrahymena

Cell Reports, 2017
RNAi-mediated positive feedback loops are pivotal for the maintenance of heterochromatin, but how they are downregulated at heterochromatin-euchromatin borders is not well understood.

Conservation of long-range synteny and microsynteny between the genomes of two distantly related nematodes [PDF]

, 2002
Comparisons between the genomes of the closely related nematodes Caenorhabditis elegans and Caenorhabditis briggsae reveal high rates of rearrangement, with a bias towards within-chromosome events.

Repeats of Unusual Size in Plant Mitochondrial Genomes: Identification, Incidence and Evolution

G3: Genes, Genomes, Genetics, 2019
Plant mitochondrial genomes have excessive size relative to coding capacity, a low mutation rate in genes and a high rearrangement rate. They also have abundant non-tandem repeats often including pairs of large repeats which cause isomerization of the ...

Heat stress-induced transposon activation correlates with 3D chromatin organization rearrangement in Arabidopsis

Nature Communications, 2020
Heat stress can activate heterochromatin-associated transposon elements (TEs). Here, the authors show that heat stress leads to global rearrangement of 3D genome and TEs activation closely correlates with 3D chromatin organization rearrangement in ...
