Article Synopsis
- Retrotransposons are important parts of the DNA in plants and animals that can make copies of themselves.
- They usually get turned off by the host's DNA control system, but some have clever ways to bypass this control.
- The ONSEN retrotransposon in a plant called Arabidopsis can activate and replicate when the plant gets hot, which helps it survive but makes things tricky for the plant's ability to manage stress.
The TTAGG repeat, the only determined telomerase-dependent sequence in the Insecta, is generally reputed to be the canonical telomeric motif within the class. By studying the distribution of telomeric DNAs in 30 coleopteran beetles using Southern hybridization, BAL 31 DNA end-degradation assay and fluorescence in situ hybridization, we showed that arrays built of a TCAGG repeat substitute for (TTAGG)n sequences in all tested species within the superfamily Tenebrionoidea. We also provided the experimental evidence that (TCAGG)n repeats represent the terminal sequences on all chromosomes of the model species Tribolium castaneum.
