Botany 2015 Colloquium: Phylogenomics and the 1000 plants (1KP) initiative

Burleigh, Gordon [1].

Large-scale syntheses of plant relationships.

Recent phylogenomic datasets, including those produced by the 1kp project, have transformed approaches to plant systematics, providing evidence of both incongruence among loci and also contradicting some previously resolved backbone relationships. Other recent projects have used supertree and supermatrix approaches to construct large-scale syntheses of plant relationships, resulting in species level trees of unprecedented size. I compare several recent approaches to synthesize plant phylogenetic relationships from either published trees or large supermatrices of mostly chloroplast loci with insights from 1kp and other plant genomic data. I discuss new approaches to evaluate incongruence among loci based on the Robinson-Foulds distance and to quantify areas of support and conflict in large-scale synthetic phylogenetic trees. Finally, I discuss how insights from new phylogenomic data can be reconciled with, and ultimately compliment, large-scale syntheses.
