Whole-Genome Duplication and Purifying Selection Contributes to the Functional Redundancy of Auxin Response Factor (<i>ARF</i>) Genes in Foxtail Millet (<i>Setaria italica</i> L.)

<div>The ML phylogenetic tree constructed by ARF proteins from four plant species. Prefixes in the protein names, including Si, Os, Zm, and At, were used as to denote the species they belong to and represent <i>S. italica</i>, <i>O. sativa</i>, <i>Z. mays</i>, and <i>Arabidopsis thaliana</i>, respectively. The phylogenetic tree could be classified into four clades, and each clade was marked with different colors. Yellow, blue, green, and red represented clades I to IV, respectively. Protein domain composition of each ARF members was also exhibited. Red diamonds represented B3 domain. Orange squares represented auxin_resp domain, and yellow diamonds indicated Aux/IAA domain.</div>
