Phylogenetic analysis of DnAGL19 and its homologs. Phylogenetic analysis of DnAGL19, DOSOC1, and homologous proteins was performed using MEGA6. A preliminary neighbor joining (NJ) tree was constructed using the Chlamydomonas reinhardtii MADS-box protein, PAC 30775785 (accession No. at Phytozome 10.2), as the out-group. The subtree containing the SOC1/TM3-like proteins is shown here. Orthologs from eudicots and monocot grasses are grouped independently, and both groups are independent from the Dendrobium SOC1/TM3-like branch (red). SOC1/TM3-like proteins from A. thaliana and rice (Oryza sativa) are shown in green and blue, respectively. Proteins are indicated by “Accession No. at Phytozome 10.2 + species common name.” DnAGL19 and DOSOC1 are orchid SOC1/TM3-like proteins from Dendrobium nobile and Dendrobium Chao Parya Smile, respectively.
