The B73 Maize Genome: Complexity, Diversity, and Dynamics

Patrick S. Schnable, +159 more
- 20 Nov 2009 - 
TL;DR: The sequence of the maize genome reveals it to be the most complex genome known to date and the correlation of methylation-poor regions with Mu transposon insertions and recombination and how uneven gene losses between duplicated regions were involved in returning an ancient allotetraploid to a genetically diploid state is reported.
Journal ArticleDOI

Regulation of heterochromatic silencing and histone H3 lysine-9 methylation by RNAi.

TL;DR: It is proposed that double-stranded RNA arising from centromeric repeats targets formation and maintenance of heterochromatin through RNAi.
Journal ArticleDOI

Transposable elements and the epigenetic regulation of the genome.

TL;DR: New insights have been gained into how silencing in eukaryotic cells has been co-opted to serve essential functions in 'host' cells, highlighting the importance of TEs in the epigenetic regulation of the genome.
Journal ArticleDOI

Transgenerational Epigenetic Inheritance: myths and mechanisms

TL;DR: Although the inheritance of epigenetic characters can certainly occur-particularly in plants-how much is due to the environment and the extent to which it happens in humans remain unclear.
