Summary
Researchers discovered three new miniature inverted-repeat transposable elements (MITEs) in termite genomes, named terMITEs. These elements show mobility and contain variable tandem repeats, offering insights into transposable element evolution.
Area of Science:
- Genomics
- Molecular Biology
- Evolutionary Biology
Background:
- Transposable elements (TEs) are mobile DNA sequences.
- Miniature inverted-repeat TEs (MITEs) are non-autonomous elements with unclear origins.
- Some MITEs form tandem arrays, potentially leading to satellite DNA.
Purpose of the Study:
- Discover and analyze novel MITEs in termite genomes.
- Investigate the mobility and repeat structures of these new MITEs.
- Determine the genomic distribution and evolutionary implications of these terMITEs.
Main Methods:
- Bioinformatic analysis of termite genomes.
- Identification and characterization of MITE sequences.
- Comparative genomics to assess distribution and copy number variation.
Main Results:
- Discovery of three new MITE families: terMITE1, terMITE2, and terMITE3.
- Evidence of past mobility for terMITE1 (Tc1/mariner) and terMITE2 (piggyBac).
- terMITE1 and terMITE2 possess variable tandem core repeats (16 bp and 114 bp).
- terMITE2 tandem duplication linked to element degeneration.
- terMITE1 and terMITE3 near coding regions; terMITE2 associated with other TEs.
- Genomic distribution potentially explained by insertional preference.
Conclusions:
- terMITEs contribute to understanding MITE evolution and origin.
- The findings support models of MITEs and tandem array evolution.
- This study enhances knowledge of polyneopteran genomes and TE dynamics.

02:13Overview of Transposition and Recombination
21.3K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

03:08LTR Retrotransposons
20.6K
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

3.2K
Transposons, or "jumping genes," are small mobile genetic elements (MGEs) that range from 700 to 40,000 base pairs in length. They are found in all organisms and can move within the same chromosome or transfer to different chromosomes. In some cases, transposons can also jump between different host DNA molecules, such as plasmids or viruses, contributing to genetic variability.Barbara McClintock first discovered these mobile genetic elements in the 1940s while studying maize genetics, and she...

02:57DNA-only Transposons
18.9K
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.

03:18Non-LTR Retrotransposons
14.1K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

02:57piRNA - Piwi-interacting RNAs
7.9K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...
