*4.6. Detection of Additional Conserved Motifs*

To identify additional conserved motifs outside the Dof domain of physic nut Dof proteins, we used Multipel Expectation Maximization for Motif Elucidation (MEME v4.11.2, Available online: http://meme.nbcr.net/meme/) [50]. The limits on maximum width, minimum width, and maximum number of motifs were specified as 5, 150, and 10, respectively. The motifs were numbered serially according to their order in MEME. Those motifs common to genes in one of the three similarity groups were designated as the group-specific signatures.
