Shared single copy genes in various combinations of angiosperm genomes. Angiosperm genomes are abbreviated as follows: Ath - Arabidopsis thaliana; Ptr - Populus trichocarpa; Vvi - Vitis vinifera; Osa - Orysa sativa. The number of tribes represents the number of PlantTribes found at medium stringency (3.0) that contain a single member from each of the genomes sampled.
