Figure 1From: Identification of shared single copy nuclear genes in Arabidopsis, Populus, Vitis and Oryzaand their phylogenetic utility across various taxonomic levelsShared 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.Back to article page
