Abstract Detail

Phylogeny and evolution of angiosperms in the era of next generation sequencing

Leebens-Mack, Jim [1], Soltis, Douglas [2].

A Roadmap for Enabling Phylogenomics across the Green Plant Tree of Life.

Phylogenomics encompasses the use of genome data to resolve species and gene family phylogenies, together with comparative investigations of genome, gene family and gene evolution. With the growing availability of reference genome assemblies and transcriptome data, phylogenomics research is yielding new insights into phylogeny and the myriad biological processes contributing to plant diversification. Increasingly precise phylogenetic placements of gene and genome duplications are elucidating their contributions to evolutionary innovations such as the origins of seeds and flowers. Gene family contractions and expansions are being identified across the tree of life and correlated with key innovations. Analyses of synteny are providing novel insights into genome evolution including the gene duplication and loss processes. However, at the same time, high quality genome assemblies are only available for a very small fraction of green plant lineages. Most of our current understanding of plant genome evolution is based on a few well-assembled and annotated genomes concentrated in just a few angiosperm families. In the last year, the Open Green Genomes and Ten Thousand Plant Genomes sequencing initiatives have been launched to generate genome assemblies across the Embryophyta and Viridiplantae phylogenies, respectively. We will discuss the scopes and objectives of each of these community-driven initiatives. Further, we will share information on data availability and dissemination for these large, open-access genome sequencing programs.
