Phylogenetic relationship among ARF/ARL proteins of rice, foxtail millet and Arabidopsis.
Full-length amino acid sequences of rice (Os), foxtail millet (Si) and Arabidopsis (At) were aligned by ClustalW and an unrooted Neighbor-Joining tree was constructed with 1000 bootstrap iterations. The tree classified the proteins into four distinct classes (I–IV), shaded with different colors. The proteins of rice and foxtail millet are represented in blue and red colored fonts, respectively.
