Diversification of chromatin organization in eukaryotes

Abstract

Our knowledge of the chromatin landscape and its regulation was originally discovered using yeast and a limited number of animals models. A wealth of studies in model plants now strongly demonstrates the conservation of certain features while illuminating the diversification of others. Here we summarize recent advances that describe specific features of chromatin organization of transcriptional units and specific regulation of heterochromatin in flowering plants. We highlight the importance of transcriptional regulation in plant chromatin organization and the need to investigate a more diverse range of species to understand the chromatin landscape in eukaryotes.
