Maximum likelihood cladogram of CSLD sequences from selected land plant species rooted with green algal CSLD sequences. The CSLD families of mosses, lycophytes, liverworts, and charophyte green algae diversified independently. Angiosperm CSLDs group by demonstrated function (filled circles) and expression (open circles) with sequences from other species. Nodes are labeled with bootstrap values (1,000 replicates). Species include Physcomitrium patens (Pp; Phytozome locus IDs; Roberts and Bushoven, 2007), Coleochaete orbicularis (KF; GenBank IDs; Mikkelsen et al., 2014), Selaginella moellendorffi (Smo; Phytozome protein IDs; Harholt et al., 2012), Marchantia polymorpha (Mapoly; Phytozome; identified by BLAST), Picea abies (MA; Phytozome protein IDs; Yin et al., 2014), Arabidopisis thaliana (AT; locus IDs; Richmond and Somerville, 2000), Populus trichocarpa (Potri; Phytozome protein IDs; Yin et al., 2014), Gossypium raimondii (Gorai; Phytozome protein IDs; Li et al., 2017), Zea mays (GRMZM; Phytozome protein IDs; Yin et al., 2014) and Oryza sativa (Os; locus IDs; Yin et al., 2014).
