Fig. 1. Comparison of the WUS protein family. (A) Alignment of the homeodomain
sequences. Asterisks indicate residues that are highly conserved in
homeodomains (Gehring et al.,
1990). (B) Alignment of the WUS box that is located
downstream of the homeodomain. No WUS box was found in WOX13 (dashed
line). (C) Alignment of the C-terminal region in a subset of the WUS family.
In A-C identical residues are in black boxes, conservative changes in gray.
(D) Dendrogram based on the sequence of the homeodomains. Bootstrap values are
given (1000 rounds). AmWUS, PhWUS, LeWUS, OzWUS, putative orthologs of
Antirrhinum, Petunia, tomato, and rice, respectively. See text for
details and references.
