Phylogenetic tree, conserved motifs and exon-intron structure analysis of flax MADS-box genes

(A) Phylogenetic tree of flax MADS-box genes.

(B) Conserved motifs of LuMADS proteins. The 10 conserved motifs are represented by different colors.

(C) Exon-intron structure of the LuMADS gene. The blue box indicates the CDS region of the gene, the orange box indicates the UTR region, and the black line indicates the intron.

(D) A conserved motif of the flax MADS gene. Motif1–Motif10 represents different conserved motifs, the numbers on the x axis represent the amino acid position, and the font size represents the relative frequency at the position.
