TL;DR: A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.

TL;DR: Across angiosperms, nested shifts in diversification led to an overall increasing rate of net diversification and declining relative extinction rates through time, and it is suggested that stochastically changing diversification rates across the phylogeny explain these patterns.

TL;DR: Analysis of transcriptomes from 24 gymnosperms and 3 outgroups indicates that polyploidy has contributed to the evolution of conifers and other gymnos perms, contrary to previous genomic research that reported an absence of polyploidsy in the ancestry of contemporary gymnOSperms.

TL;DR: This study provides a major stepping-stone in the understanding of land plant evolutionary genomics by providing the first homosporous fern reference genome, as well as insights into the processes underlying the formation of these massive genomes.

TL;DR: New molecular and physiological evidence is reported for the presence of active stomatal control in ferns and of the key ABA-responsive genes identified, which fit the general ABA signaling pathway constructed from Arabidopsis and Hordeum vulgare.
