Fig. 4From: 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 analyses of MADS-box genes from two orchids, Dendrobium officinale and Phalaenopsis equestris. The AGL12, AGL15 and FLC subfamilies were lost from the two orchids. The phylogenetic tree was constructed using MEGA 7 [33] based on the alignment of MADS-box proteins by MAFFT 7 [34] with the NJ method. Numbers besides branches represent bootstrap support values from 1000 replicationsBack to article page
