Genome-wide DNA methylation maps during dehydration in leaf tissues of Boea hygrometrica

ABSTRACT: To examine the Boea hygrometrica genome methylation landscape and assess its functional significance during dehydration, we generated the first single-base resolution genome methylation maps for leaf tissues of hydrated, dehydrating to 70% RWC and dehydrating to 10% RWC (desiccating). The overall density of methyl-cytosine was not broadly altered by dehydration. There is, however, a small increase in intensity both for the whole genome and regionally during the first dehydration step (70% RWC) returning to near hydrated levels as leaves desiccate. We identified 5575 differentially methylated region-related genes during dehydration. The finding may provide an important clue for exploring molecular mechanisms and the regulation of desiccation tolerance at the whole-genome level.
