Phylogenomics of the seedless land plants.

The seedless vascular-plant groups (lycophytes and ferns) and bryophytes (mosses, liverworts, hornworts) collectively represent most of the early diversity of land plants. They are key to understanding the origin and diversification of major plant structures (such as roots, leaves and vascular tissue), shifts in the alternation of generations (such as the origin of a dominant diploid phase and heterospory), and transitions associated with invasion of land (such as the evolution of the cuticle). However, these lineages are under-represented as model plant systems, and there are very few genomic resources available to researchers. Here we present transcriptome data from a phylogenetically diverse sampling of ~175 species of seed-free land plants, produced as part of the 1KP project with the assistance of a large number of collaborators. We use a variety of approaches to revisit classical and contemporary phylogenetic hypotheses for higher-order relationship within the monilophytes, lycophytes and the major bryophyte groups, which to date have been investigated using only a handful of loci.
