Extended Data Fig. 3 | The phylogenetic tree of MADS-box genes of
N. colorata. a, The MADS-box genes are divided into type I and type II, and the
latter was subdivided into MIKCc and MIKC*. Branches of various species are
shown in different colours, with the colour code below the tree. The nodes
representing three tandem duplication events (TD1, TD2, and TD3 in b) are
marked with red circles. b, Genomic regions with the duplicated genes derived
from the three tandem duplication events (TD1, TD2 and TD3).
