Role of epigenetic (DNA methylation) as a component of phenotypic plasticity and adaptation in response to water deficit in forest trees

Our objective: A better understanding of the role of DNA methylation in trees and the potential uses for forest tree breeding, management of conservation of genetic resources.
Our skills: We are developing an integrative multi-omic approach combining forward and reverse (epi)genetic as well as population epigenomics. For 20 years, we have continuously followed the evolution of DNA methylation methods (Figure 2) as shown below. Actually, WGBS (Whole Genome Bisulfite Sequencing), Capture Bisulfite Sequencing and Global methylation with HPLC are our references. Using these approaches and bioinformatics, we analyse DNA methylation at different scales (Figure 3).
