L. schismatica MADS Box B and C Orthologs.

(A) B and C MADS domain protein sequences of diverse angiosperms. L. schismatica orthologs possess diagnostic C-terminal motifs characteristic of each linage.

(B) Bayesian phylogenetic analysis (AG, left; B genes, right) corroborate the orthology of the L. schismatica genes (AG in red; AP3 and PI in blue) to C and B genes of Arabidopsis, respectively. Trees are supported with high posterior probabilities showed for the main branches. The L. schismatica sequences were nested within monocots. The MADS box has been excluded from this analysis to align domains with the most informative sites. Gymnosperm genes were used as outgroups. Larger alignments confirmed these results (see Supplemental Figure 1 online).
