Conserved Leu in the LxLxL motif are in bold. The most conserved amino acids in domain I of A. thaliana IAA proteins are in uppercase. IAA32 and IAA33, which lack a LxLxL motif, are not shown. For nomenclature of A. thaliana IAA proteins, see Liscum and Reed (2002). NtERF3, AtERF4, and AtSUPR correspond to the EAR motifs within the repression domains of N. tabacum ERF3, A. thaliana ERF4, and A. thaliana SUPERMAN, respectively.
