DMRs induced by drought, cold, heat, herbivory, rust infection and salicylic acid in the Lombardi poplar

We aimed to provide a comprehensive characterization of the stress-induced DNA methylation variation in the Lombardi poplar. We made use of a recent reference genome assembly for this particular clone in order to examine DNA methylation responses to a variety of abiotic (drought, cold, heat) and abiotic (herbivory, rust infection, salicylic acid) stresses. Since we sampled adult trees sampled across Europe, we were particularly interested to determine consistent stress-induced changes irrespective of the different methylation backgrounds from where the cuttings originated.
