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

The large‐scale replacement of gymnosperms by angiosperms in many ecological niches
over time and the huge disparity in species numbers have led scientists to explore factors …

The large size and complexity of most fern genomes have hampered efforts to elucidate
fundamental aspects of fern biology and land plant evolution through genome-enabled …

Plants have substantially higher gene duplication rates compared with most other
eukaryotes. These plant gene duplicates are mostly derived from whole genome and/or …

Polyploidy or whole genome duplication (WGD) is a major contributor to genome evolution
and diversity. Although polyploidy is recognized as an important component of plant …

The amount of DNA in the nucleus of a cell is commonly referred to as the genome size or C-
value and people have been estimating this character in plants and animals for over 50 …

Ferns are notorious for possessing large genomes and numerous chromosomes. Despite
decades of speculation, the processes underlying the expansive genomes of ferns are …

Background Because of their phylogenetic position and unique characteristics of their
biology and life cycle, ferns represent an important lineage for studying the evolution of land …

Ferns are one of the few remaining major clades of land plants for which a complete
genome sequence is lacking. Knowledge of genome space in ferns will enable broad-scale …

Twenty-first century technology is addressing many of the questions posed by 20th-century
biology. Although the new approaches, especially those involving genomic data and …
