RESULTS
ONSEN preferentially integrates into coding exons enriched for the H3K27me3 histone mark and H2A.Z histone variant
… We compared our set of novel ONSEN insertions with those previously described in wild plants (natural insertions, Figure 2) and in NRPD1 defective plants (nrpd1 insertions, Figure 2) (44,78) …
… We used our novel hcLines insertions (n= 237) as well as the previously identified nrpd1 (n= 281) and natural (n= 279) insertions (44,78) …
Figure 2 caption
Genome-wide distribution of novel ONSEN insertions in the Arabidopsis genome. Novel insertions detected in this study are represented in blue (hcLines) and those previously reported (44,78) for natural populations and nrpd1 plants in grey and orange, respectively. The density plots below the grey chromosome schemes show gene density (green) and TE density (yellow). Units are given in Mb.
DISCUSSION
… Here we found that ONSEN had a clear preference for chromatin states rich in H2A.Z (as also documented by (78)) and H3K27me3 …
… It is notable that ONSEN preferentially integrated in genes with the chromatin states 5 and 2 that show a low expression level in adult plants and are often associated with typical polycomb chromatin
or repressed regions ((78) and this work) …
… As the insertion sites observed in the hcLines are similar to the ones previously documented for nrpd1 and natural populations (44,78), both in terms of chromatin states and genomic features, we concluded that the activation through the exposition to α-amanitin and zebularine did not impact ONSEN insertion site preferences …
… These genes and functions have recently been highlighted to play a role in response to abiotic stress in plants (70,71) and it goes in the same direction as a previous observation stating that ONSEN preferentially targets environmentally responsive genes (78) …
