| "Genetic variability is one of the means for plant species to cope with environmental changes, but not the only one. Epigenetic variability creates potential for evolution of plant phenotypic plasticity which may be critical for long-lived species, such as forest trees [1]. Phenotypic plasticity enables plants to adapt to environmental changes by modifying their development and function. Both adaptation strategies will be critical for organisms to endure rapid and abrupt changes of climate. Exposure to environmental stress prompts epigenetic changes, which regulate the transcriptomic stress response. Among known epigenetic mechanisms, cytosine DNA methylation is responsive to different stresses. Cytosine methylation is relatively stable, may be transgenerationally inheritable and in addition could underpin a molecular mechanism of stress memory in plants. The high levels of cytosine methylation, the low correlation with genetic variation in some cases, and the observed association with adaptive traits related to population differentiation, suggest a role for methylation inheritance in adaptation and evolution of woody and herbaceous species. From the above mentioned arguments we established different experimental approaches to assess the epigenetic variation caused by changes in DNA methylation in woody plants. " | |
