DNA replication requires the faithful propagation of both genetic and epigenetic information. There is evidence that DNA polymerases play a role in transcriptional silencing, but the extent of their contribution and how it relates to heterochromatin maintenance is unclear. To get a better understanding of the role of POL2A, the catalytic subunit of the DNA polymerase epsilon, into maintaining heterochromatin silencing, we performed mRNA-seq on Arabidopsis plants carrying a new hypomorphic pol2a mutation. We deepened our analysis by profiling transcriptomes of other silencing mutants or combinations of pol2a with other mutations.

Instrument: Illumina HiSeq 2500
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: PolyA
Layout: SINGLE
Construction protocol: 13-day-old rosette were cut out and flash frozen in liquid nitrogen Plants were grown in soil in a growth cabinet at 23°C, 50% humidity, using long day conditions (16h light, 8h dark). Total RNA was extracted in TRIzol reagent, precipitated with isopropanol and washed two times in ethanol 70%. RNA was then DNase treated using 1 unit of RQ1 DNAse (Promega) per μg of RNA, following manufacturer's instructions. Following DNase treatment, RNAs were further purified in phenol-chloroform. RNA integrity was assessed by running 1ug of RNA through a agarose gel supplemented with formaldehyde after denaturation in 1X MOPS 4% formaldehyde for 15 minutes at 65°C. Sequencing libraries were generated at Fasteris S.A. (Geneva, Switzerland).
