dc.description.abstract | One of the strategies of plant adaptation to stress is the modulation of gene expression, which may result from the
regulation of DNA methylation. This study attempted to characterize and compare the barley methylome of leaves
and roots under water-deficiency treatment and in the subsequent rewatering phase. Our results, obtained using
methylation-sensitive amplification polymorphism sequencing analysis, indicated that the overall DNA methylation
level in the barley genome was high and in general stable under water-deficiency conditions. Nevertheless, numerous
differentially methylated sites (DMSs) were induced by stress in the leaves and roots. Equal proportions of novel
stress-induced methylation and demethylation events were observed within the genes in the leaves, but new methylations
dominated in the roots. Repetitive elements preferentially underwent demethylation in the leaves and novel
methylations in the roots. Importantly, rewatering and plant recovery resulted in the reversibility of the majority of
stress-induced methylation events, but this process was more efficient in the leaves than in the roots. Different biological
processes were enriched within the subsets of the DMSs that were identified in the genic regions of leaves and
roots. We assume that the organ specificity of the methylome changes in response to water deficiency might be an
important regulatory mechanism that leads to multi-level mechanisms of stress tolerance in barley. | pl_PL |
