DNA sequencing of Arabidopsis thaliana nrpd1-3 background with novel insertions of LTR retrotransposon ONSEN/COPIA78.


ABSTRACT: The intent of the experiment was to infer, from re-sequencing of genomic DNA, the coordinates of neo-insertions from activated ONSEN/COPIA78 LTR retrotrasnposon in Arabidopsis thaliana. For this, we performed Illumina 75 bp pair-end PCR-free DNA genome re-sequencing in several independent lines of RdDM mutant nrpd1-3.

Retrotransposons (RTs) can rapidly increase in copy number due to periodic bursts of transposition. Such bursts are mutagenic and thus potentially deleterious. However, certain transposition-induced gain-of-function or regulatory mutations may be of selective advantage. How an optimal balance between these opposing effects arises is not well characterized. Here, we studied transposition bursts of a heat-activated retrotransposon family in <i>Arabidopsis</i> We recorded a high inter and intraplan  ...[more]
