The regulation of parental genome dosage is of fundamental importance in animals and
plants, as exemplified by X-chromosome inactivation and dosage compensation. The ‘triploid …

In eukaryotic cells, histones are subject to a large number of posttranslational modifications
whose sequential or combinatorial action affects chromatin structure and genome function. …

The early endosperm tissue of dicot species is very difficult to isolate by manual dissection.
This protocol details how to apply the INTACT (isolation of nuclei tagged in specific cell types…

Parental genomes in the endosperm are marked by differential DNA methylation and are
therefore epigenetically distinct. This epigenetic asymmetry is established in the gametes and …

MADS-box transcription factors (TFs) are ubiquitous in eukaryotic organisms and play major
roles during plant development. Nevertheless, their function in seed development remains …

Deposition of the H2A.Z histone variant by the SWR1 complex (SWR1-C) in regulatory
regions of specific loci modulates transcription. Characterization of mutations in Arabidopsis …

Hybrid seed lethality as a consequence of interspecies or interploidy hybridizations is a
major mechanism of reproductive isolation in plants. This mechanism is manifested in the …

Protein kinase CK2 is an evolutionary conserved Ser/Thr phosphotransferase composed of
two distinct subunits, α (catalytic) and β (regulatory), that combine to form a tetrameric …

Background Imprinted genes are epigenetically modified during gametogenesis and maintain
the established epigenetic signatures after fertilization, causing parental-specific gene …

In response to stress treatments, microspores can be reprogrammed to become totipotent
cells that follow an embryogenic pathway producing haploid and double-haploid embryos …
