Phylogenetic tree constructed by the neighbor-joining method using MADS-box genes from
, Arabidopsis and Rice. (a) Phylogenetic analysis of 138 type I MADS-box proteins from B. rapa (67), Arabidopsis (43) and Rice (28). (b) Phylogenetic analysis of type II B. rapa, Rice and Arabidopsis MADS-box proteins. 181 type II MADS-box proteins from B. rapa (100), Arabidopsis (43) and rice (38) showing 13 MIKCc clades and MIKC* group as marked in the figure.
