DNA methylation in plant adaptation to changing environment
Abstract
The article presents a mini review of the current and updated, significantly expanded in recent decades information on DNA methylation changes in plant responses to unfavorable environmental factors, which allows it to consider as ecological epigenetics (eco-epi). Epigenetic regulation of gene expression is considered as the main source of adaptive phenotypic plasticity. We emphasize a great potential of further studies of the epigenetic regulatory systems in phenotypic plasticity of a wide range of non-model species in natural populations and agrocenoses for our advanced understanding of the molecular mechanisms of plant existence in the changing environment and thus for forecasting the effects of global climate changes on biodiversity and crop yield. Specific taxa of the Ukrainian flora which, in authors’ opinion, are promising and interesting for this type of research, are recommended.
