Sequence Analysis of IAA9.
Sequence comparison of IAA9, putative orthologs from other plants, and other members of the Aux/IAA protein family. Conserved residues are shaded in black, dark gray shading indicates similar residues in at least 7 out of 12 of the sequences, and light gray shading indicates similar residues in 4 to 6 out of 12 of the sequences. The four conserved domains I, II, III, and IV are underlined. Conserved basic residues that putatively function as NLS are indicated by closed circles on the top of the alignment. Putative polyproline II (Pxx)2 conformation residues are indicated by arrows.
