Phylogenetic relationships of YUCCAs in vascular plants, moss, and algae. The bubbles indicate the five YUCCA subgroups. The dots symbolize the species to which the YUCCA proteins in each group belong (brown: rice [monocot]; purple: Arabidopsis thaliana [eudicot]; cyan-blue: apple [eudicot]; green: Selaginella moellendorffii [lycophyte]; and dark green: Physcomitrella patens [moss]).
