Phylogenetic relationships and motif compositions of membrane-bound FAD genes from <i>G</i>. <i>raimondii</i>, <i>Arabidopsis</i> and rice.

<p>Unrooted phylogenetic tree (left panel): Four subfamilies marked with different color backgrounds are labeled as Omega, Sphingolipid, Front-end and First. Motif compositions (right panel): Protein sequences are indicated by thick gray lines, and the conserved motifs are represented by different colored boxes. The length (amino acids) of the protein and motif can be estimated using the scale bar at the top.
