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. Less...
