Fig. 2From: 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 orchidClassification of the total of 865 MIKCC proteins based on phylogenetic analysis. The MIKCC proteins were divided into 13 subfamilies: AG, AGL6, AGL12, AGL15, AGL17, BS, DEF/GLO, FLC, SEP, SQUA, SVP, TM3/SOC1 and TM8. The phylogenetic tree was constructed by MEGA 7 [33] with the NJ method based on alignments by MAFFT 7 [34]. The phylogenetic tree containing bootstrap values can be observed in Additional file 6: Figure S4Back to article page
