Summary of the three experiments used for the methylome comparative approach. Plant materials, water regimes, samples, and the previously published ecophysiological or epigenomic data used for the analyses in this paper are cited. For experiment 1, the field trial was located near Orléans, France, under two different water regimes (ORLWW and ORLWD); WW, Well watered (considered favorable for growth); WD, water deficit (considered unfavorable for growth). For experiment 2, field trials were located in Echigey (a site with favorable growing conditions) and Saint-Cyr-en-Val or Guémené, France (both sites with unfavorable growing conditions). For experiment 3, poplar trees were grown in a greenhouse under three water regimes: WW, WD, and water deficit followed by rewatering (WD-RW), also considered unfavorable for growth.
