Plastome phylogenomic study of Gentianeae (Gentianaceae): Widespread gene tree discordance and its association with evolutionary rate heterogeneity of plastid genes

Plastome-scale data have been prevalent in reconstructing the plant Tree of Life. However, phylogenomic studies currently based on plastomes rely primarily on maximum likelihood inference of concatenated alignments of plastid genes, and thus phylogenetic discordance produced by individual plastid genes has generally been ignored.
