Phylogenetic relationships among ‘green plants’ and the presence of GRF-GIF genes. Depicted are the relationships among the three lineages of ‘green plants’: chlorophytes, charophytes, and land plants. The numbers of GRF and GIF are indicated in black boxes, while diamond bullets indicate the presence of the WRC domain. Species depicted in gray tone only have whole transcriptomic resources, but no whole genome sequenced. n designates ‘not present’; asterisks indicate that the GRF genes are predicted to encode three consecutive WRC domains after the QLQ domain.
