Genome size is a biodiversity trait that shows staggering diversity across eukaryotes, varying
over 64,000-fold. Of all major taxonomic groups, land plants stand out due to their …

Next-generation sequencing (NGS) technologies using DNA, RNA, or methylation
sequencing have impacted enormously on the life sciences. NGS is the choice for large …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …

Highlights•Post-polyploid diploidization (PPD) in angiosperms usually operates by
descending dysploidy.•PPD is acting with differing intensities and rates.•Multiple base …

Background The growing wealth of knowledge on whole-plant genome sequences is
highlighting the key role of transposable elements (TEs) in plant evolution, as a driver of …

A large proportion of genomic information, particularly repetitive elements, is usually ignored
when researchers are using next-generation sequencing. Here we demonstrate the …

Species of Nicotiana grow naturally in different parts of the world and have long been used
both medicinally and recreationally by human societies. More recently in our history …

Complexes of diploid and polyploid species have formed frequently during the evolution of
land plants. In false flax (Camelina sativa), an important hexaploid oilseed crop closely …

We investigate the timing of diversification in allopolyploids of Nicotiana (Solanaceae)
utilising sequence data of maternal and paternal origin to look for evidence of a lag phase …
