Novel insights into chloroplast genome evolution in the green macroalgal genus Ulva (Ulvophyceae, Chlorophyta)

open access: yesFrontiers in Plant Science, 2023
To understand the evolutionary driving forces of chloroplast (or plastid) genomes (plastomes) in the green macroalgal genus Ulva (Ulvophyceae, Chlorophyta), in this study, we sequenced and constructed seven complete chloroplast genomes from five Ulva ...

Ontology for genome comparison and genomic rearrangements

open access: yesComparative and Functional Genomics, 2004
AbstractWe present an ontology for describing genomes, genome comparisons, their evolution and biological function. This ontology will support the development of novel genome comparison algorithms and aid the community in discussing genomic evolution. It provides a framework for communication about comparative genomics, and a basis upon which further ...

Genome rearrangement algorithms [PDF]

open access: yes, 2011
With the increasing amount of sequenced genomes, a comparison of species based on these data becomes more and more interesting. In contrast to the classical approach, where only point mutations were considered, genome rearrangement problems ignore small mutations and only consider large-scale mutations that change the gene order on the chromosomes ...

Super short operations on both gene order and intergenic sizes

open access: yesAlgorithms for Molecular Biology, 2019
Background The evolutionary distance between two genomes can be estimated by computing a minimum length sequence of operations, called genome rearrangements, that transform one genome into another.

The Complete Mitogenome of Redheaded Pine Sawfly, Neodiprion lecontei (Hymenoptera: Diprionidae): Duplication of trnR Gene and Rearrangement in the ARNS1EF Gene Cluster

open access: yesCumhuriyet Science Journal, 2022
Neodiprion is a genus belonging to the small sawfly family Diprionidae, feeding the plant family Pinaceae entirely. Here, the complete mitogenome of the redheaded pine sawfly Neodiprion lecontei (Hymenoptera: Diprionidae) was assembled, annotated as ...

Two Sets of Piwi Proteins Are Involved in Distinct sRNA Pathways Leading to Elimination of Germline-Specific DNA

open access: yesCell Reports, 2017
Piwi proteins and piRNAs protect eukaryotic germlines against the spread of transposons. During development in the ciliate Paramecium, two Piwi-dependent sRNA classes are involved in the elimination of transposons and transposon-derived DNA: scan RNAs ...

The complete mitochondrial genome of Cryptotermes declivis Tsai et Chen (Isoptera: Kalotermitidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete mitochondrial genome (mitogenomes) of Cryptotermes declivis were revealed. The circular mitogenome of C. declivis (accession number MK599465) has a length of 15678 bp and an overall G + C content of 35.07%.

Advances in the Application of Plant Chromosome Rearrangement in Crop Genetic Improvement

open access: yesGuangdong nongye kexue
Chromosome rearrangement is a mechanism that can lead to the loss, duplication, translocation and inversion of DNA segments, thereby altering the genomic structure and providing possibilities for creating new variable traits.

Multiple Intraspecific Variations of Mitochondrial Genomes in the Green-Tide Forming Alga, Ulva compressa Linnaeus (Ulvophyceae, Chlorophyta)

open access: yesFrontiers in Marine Science, 2020
To gain further insights into intraspecific evolution of Ulva mitochondrial genomes, the mitogenomes of three morphotypes of the green-tide forming alga, Ulva compressa Linnaeus from China and United States, were sequenced and compared with the available

Genomic rearrangements in prostate cancer [PDF]

open access: yesCurrent Opinion in Urology, 2015
Genomic instability is a fundamental feature of human cancer, leading to the activation of oncogenes and inactivation of tumor suppressors. In prostate cancer (PCA), structural genomic rearrangements, resulting in gene fusions, amplifications, and deletions, are a critical mechanism effecting these alterations.
