Fig. 5From: Genome-wide identification and classification of MIKC-type MADS-box genes in Streptophyte lineages and expression analyses to reveal their role in seed germination of orchidPhylogenetic relationships and expression pattern of SQUA (a), DEF/GLO (b), AG (c) and SEP (d) subfamily proteins from Dendrobium officinale (Do), Phalaenopsis equestris (Pe) and Arabidopsis thaliana (At). The phylogenetic tree was constructed using MEGA 7 [33] with the NJ method and 1000 bootstrap replications based on the alignment of MADS-box proteins by MAFFT 7 [34].
