TL;DR: Highly integrated maps of the epigenome, mRNA, and small RNA transcriptomes of two rice subspecies and their reciprocal hybrids reveal that gene activity was correlated with DNA methylation and both active and repressive histone modifications in transcribed regions.

TL;DR: It is found that increased DNA methylation in both hybrid genomes, possibly directed by the RdDM pathway, may play a role in heterosis and 77 genes sensitive to methylome remodeling were transcriptionally repressed in both reciprocal hybrids.

TL;DR: It is demonstrated that Arabidopsis CULLIN4 (CUL4) associates with the CDD complex and a common catalytic subunit to form an active E3 ubiquitin ligase both in vivo and in vitro.

TL;DR: This analysis indicated that histone modification patterns are set up very early and are relatively stable during Arabidopsis (Arabidopsis thaliana) seedling development and suggests that light-regulated changes in histone modifications might be an intricate part of light-controlled gene transcription.

TL;DR: The results suggest that local transcriptional activity may reflect the organization of the corresponding part of the chromosome and indicate that epigenetic regulation plays an important role in correlating chromosomal organization with transcriptionalactivity.
