Comparative analyses of DMRs. Populus nigra x (Populus deltoids x Populus nigra)

We clarify the role of the DNA methylation by using microarrays in the shoot apical meristem (SAM) of Populus × euramericana clones dormant or active and submitted to contrasted environments. This work aimed at characterizing: (i) the range of genetic and environmental variations of global DNA methylation and its correlation with biomass production, (ii) mitotically-conserved DMRs in winter-dormant SAM and (iii) common DMRs with their corresponding genes network and their biological role in phenotypic plasticity and stress memory toward natural environment conditions. Overall design: For each conditions one sample was used
