A Lombardy poplars. B Location of the collection sites of the Lombardy poplar ramets included in the DNA pools. The number of trees included in each DNA pool is indicated on the map. The DNA pools were categorized in three groups for the analysis of differential methylated regions. The grouping was based on the mean temperature in January at the location of the Lombardy poplar ortets calculated for the period 1965–2015 (data from CRU TS Version 4.05). (green; 1.83–3.41°C; blue; − 1.40°C to − 1.18°C, purple; 4.97–8.02°C)
