Arabidopsis EAR motif-containing proteins described in the literature. The 49 proteins are divided into two groups based on the sequence conservation pattern within the core EAR motif sites (highlighted in color). The alignment includes 12 amino acid residues upstream and downstream of the EAR motif, or up to where the nominal 12-amino acid sequence is abridged by encountering the first or last amino acid of the protein. A, The DLNxxP motif is conserved in some members of class II ERFs, TFIIIA-type ZFPs, and ABI3/VP1 family proteins. B, The LxLxL motif is conserved in AUX/IAAs and some members of the MYB and HD-Zip family proteins. Sequence logos (Crooks et al., 2004) illustrating the frequency of amino acids within the EAR motifs are presented below the respective alignments.
