Type of AHL proteins and their AT-hook motifs in land plants. Ice-Logo analysis of the Type-I AT-hook motifs (a) and Type-II AT-hook motifs (b) in land-plant AHL proteins. The star symbol denotes the core sequence of the AT-hook motif. The conserved sequence downstream of the core sequences in Type-I and Type-II AT-hook motifs were pointed out by the triangle and diamond symbols accordingly. (c) Topology of three types of AHL proteins identified in land plants based on the combination of AT-hook motifs and PPC domain.
