Ultrastructure variations in Sphagnum denticulatum ecotypes in response to desiccation stress matter to conservation

Global warming and peat bogs drying are having a strong negative effect on the survival of endangered peat mosses. Here, we aimed to identify ultrastructural and physiological trait variation during dehydration and rehydration in the (sub-)meristematic cells of buds among clonally propagated individuals of Sphagnum denticulatum in relation to their ecological origin.
