Abstract

Read online

Active DNA demethylation is required for sexual reproduction in plants, but the underlying mechanisms are unknown. Here, the authors show that the DNA glycosylases DEMETER and REPRESSOR OF SILENCING 1 enable the DNA demethylation-dependent activation of genes involved in pollen tube progression.
