Evolution of genome space occupation in ferns: linking genome diversity and species richness.

ABSTRACT:

Background and aims

The dynamics of genome evolution caused by whole genome duplications and other processes are hypothesized to shape the diversification of plants and thus contribute to the astonishing variation in species richness among the main lineages of land plants. Ferns, the second most species-rich lineage of land plants, are highly suitable to test this hypothesis because of several unique features that distinguish fern genomes from those of seed plants. In this study, we tested the hypothesis that genome diversity and disparity shape fern species diversity by recording several parameters related to genome size and chromosome number.

Methods

We conducted de novo measurement of DNA C-values across the fern phylogeny to reconstruct the phylogenetic history of the ge
