      abstract     = {Seed dormancy is a crucial developmental transition that
                      affects the adaption and survival of plants. Arabidopsis
                      DELAY OF GERMINATION 1 (DOG1) is known as a master regulator
                      of seed dormancy. However, although several upstream factors
                      of DOG1 have been reported, the exact regulation of DOG1 is
                      not fully understood. Histone acetylation is an important
                      regulatory layer, controlled by histone acetyltransferases
                      and histone deacetylases. Histone acetylation strongly
                      correlates with transcriptionally active chromatin, whereas
                      heterochromatin is generally characterized by hypoacetylated
                      histones. Here we describe that loss of function of two
                      plant-specific histone deacetylases, HD2A and HD2B, resulted
                      in enhanced seed dormancy in Arabidopsis. Interestingly, the
                      silencing of HD2A and HD2B caused hyperacetylation of the
                      DOG1 locus and promoted the expression of DOG1 during seed
                      maturation and imbibition. Knockout of DOG1 could rescue the
                      seed dormancy and partly rescue the disturbed development
                      phenotype of hd2ahd2b. Transcriptomic analysis of the
                      hd2ahd2b line shows that many genes involved in seed
                      development were impaired. Moreover, we demonstrated that
                      HSI2 and HSL1 interact with HD2A and HD2B. In sum, these
                      results suggest that HSI2 and HSL1 might recruit HD2A and
                      HD2B to DOG1 to negatively regulate DOG1 expression and to
                      reduce seed dormancy, consequently, affecting seed
                      development during seed maturation and promoting seed
                      germination during imbibition.},
