Strong and robust support is found for a sister-group relationship between land plants and one group of streptophyte green algae, the Zygnematophyceae, and suggests that phylogenetic hypotheses used to understand the evolution of fundamental plant traits should be reevaluated.
Recently Formed Polyploid Plants Diversify at Lower Rates
Likelihood-based analyses indicate that polyploids generally exhibit lower speciation rates and higher extinction rates than diploids, providing the first quantitative corroboration of the dead-end hypothesis.

It is found that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns.
A community‐derived classification for extant lycophytes and ferns
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.
Data access for the 1,000 Plants (1KP) project
How to access the data used in a phylogenomics analysis of the first 85 species, and how to visualize the gene and species trees of the 1KP project.
Paralogous Radiations of PIN Proteins with Multiple Origins of Noncanonical PIN Structure
The results have important implications for plant evolution as they suggest that structurally divergent PIN proteins that arose in paralogous radiations contributed to the convergent evolution of organ systems in different land plant lineages.
The Physcomitrella patens chromosome-scale assembly reveals moss genome structure and evolution.
More non-seed plant genomes are needed to unravel how plant genomes evolve, and to understand whether the P. patens genome structure is typical for mosses or bryophytes, it is found that 57% of the genome comprises transposable elements (TEs), some of which may be actively transposing during the life cycle.

It is proposed that the most recent common ancestor of extant land plants and green algae was preadapted for symbiotic associations and employed these gene networks to colonize land successfully.
Phytochrome diversity in green plants and the origin of canonical plant phytochromes
It is shown that canonical plant phytochromes originated in a common ancestor of streptophytes (charophyte algae and land plants) and Surprisingly, the phy tochrome portions of algal and land plant neochromes, a chimera ofphytochrome and phototropin, appear to share a common origin.

This study confirmed computationally predicted noncanonical translation events and uncovered unannotated small proteins that likely have important functions in plants and provides a valuable resource for plant genomics and an efficient optimization strategy for ribosome profiling in other organisms.
