Release from the dormant state requires exposure to a period of chilling temperatures similar to the vernalization required for flowering in Arabidopsis. Over the past decade, genomic DNA (gDNA) methylation and transcriptome studieshave revealed signatures of chromatin regulation during active growth and winter dormancy. To date, only a few chromatin modification genes, as candidate regulators of these developmental stages, have been functionally characterized in trees. In thiswork, we summarize the major findings of the chromatin-remodeling role during growthdormancycycles and we explore the transcriptional profiling of vegetative apical bud and stem tissues during dormancy. Finally, we discuss genetic strategies designed to improve the growth and quality of forest trees.
