Figure 1.

Phylogenetic analysis of MP genes from M. micrantha and four other species, namely, A. thaliana, C. nankingense, H. annuus, and L. sativa. I~IV represent the MP proteins of the five species divided into four independent clades. The tree was constructed via the neighbor-joining method based on the protein sequence alignments. The numbers on the branches represent bootstrap values obtained from 1000 replicates. The branch lengths are proportional to the percentage of sequence difference (scale bar, 0.05% difference). The red triangle represents the M. micrantha gene Mm01G000655; the blue circles represent two protein-encoding genes in A. thaliana.
