Database documentation of retrotransposon insertion polymorphisms.
Retrotransposons constitute more than 40 percent of the human genome with L1, Alu, SVA, and HERVs known to remain active in transposition. Retrotransposition contribute to genetic diversity in the form of retrotransposon insertion polymorphism (RIP) that is defined as the presence or absence of a retrotransposon insertion among human populations at a specific genomic location. So far close to 5...
متن کاملRetrotransposon evolution in diverse plant genomes.
Retrotransposon or retrotransposon-like sequences have been reported to be conserved components of cereal centromeres. Here we show that the published sequences are derived from a single conventional Ty3-gypsy family or a nonautonomous derivative. Both autonomous and nonautonomous elements are likely to have colonized Poaceae centromeres at the time of a common ancestor but have been maintained...
متن کاملeuL1db: the European database of L1HS retrotransposon insertions in humans
Retrotransposons account for almost half of our genome. They are mobile genetics elements-also known as jumping genes--but only the L1HS subfamily of Long Interspersed Nuclear Elements (LINEs) has retained the ability to jump autonomously in modern humans. Their mobilization in germline--but also some somatic tissues--contributes to human genetic diversity and to diseases, such as cancer. Here,...
متن کاملMASiVE: Mapping and Analysis of SireVirus Elements in plant genome sequences
UNLABELLED We present MASiVE, an expertly built tool for the large-scale, yet sensitive and highly accurate, discovery, preliminary analysis and insertion age estimation of intact Sirevirus LTR-retrotransposons in plant genomic sequences. Validation was based on the recently available and annotated large maize chromosome one. Results show a considerable improvement in the annotation of Sireviru...
متن کاملPMRD: plant microRNA database
MicroRNAs (miRNA) are approximately 21 nucleotide-long non-coding small RNAs, which function as post-transcriptional regulators in eukaryotes. miRNAs play essential roles in regulating plant growth and development. In recent years, research into the mechanism and consequences of miRNA action has made great progress. With whole genome sequence available in such plants as Arabidopsis thaliana, Or...
