Patterns and processes of diploidization in land plants
Most land plants are now known to be ancient polyploids that have rediploidized.
Diploidization involves many changes in genome organization that ultimately restore …

RNA-directed DNA methylation: the evolution of a complex epigenetic pathway in flowering plants
RNA-directed DNA methylation (RdDM) is an epigenetic process in plants that involves both
short and long noncoding RNAs. The generation of these RNAs and the induction of RdDM …

Are polyploids really evolutionary dead-ends (again)? A critical reappraisal of Mayrose et al. (2011)
Background Throughout the past century, hybridization and polyploidization have variously
been viewed as drivers of biodiversity (eg Arnold, 1997) or evolutionary noise, unimportant …
