  bibo_abstract:
  - The Arabidopsis thaliana central cell, the companion cell of the egg, undergoes
    DNA demethylation before fertilization, but the targeting preferences, mechanism,
    and biological significance of this process remain unclear. Here, we show that
    active DNA demethylation mediated by the DEMETER DNA glycosylase accounts for
    all of the demethylation in the central cell and preferentially targets small,
    AT-rich, and nucleosome-depleted euchromatic transposable elements. The vegetative
    cell, the companion cell of sperm, also undergoes DEMETER-dependent demethylation
    of similar sequences, and lack of DEMETER in vegetative cells causes reduced small
    RNA–directed DNA methylation of transposons in sperm. Our results demonstrate
    that demethylation in companion cells reinforces transposon methylation in plant
    gametes and likely contributes to stable silencing of transposable elements across
    generations.@eng
