    Transcriptional regulation through association of chromatin domains with nuclear compartments

    The position of a genomic locus within the nucleus and relative to nuclear domains such as the nuclear periphery, the nucleolus, chromocenters or Polycomb bodies has the potential to affect its expression.

    Recent developments including techniques such as ChIP-seq and RNA-seq coupled to Chromatin Conformation Capture (3C) applied to the whole genome (Hi- C) have greatly improved our understanding of genome organization in nuclear space and revealed plant-specific features of nuclear architecture. Uniting these approaches with the power of genetics will provide breakthroughs in our understanding of plant nuclear architecture and genome expression. WG2 will integrate these different methodologies and deploy a series of complementary approaches to study the spatial organization of genomic loci in relation to its local chromatin features and its transcriptional activity.
