Fig. 1.

UPGMA-based distance tree showing the similarity between P. persica and Arabidopsis small GTPase proteins and their distribution within the RAB, ARF/ARL/SAR, ROP, and RAN families. Two different graphic representations of the same tree are combined to show both the general partition in families and the detail of each group. Families and subfamilies of Arabidopsis small GTPases, previously identified by Vernoud et al. (2003), and the 24 sequences from peach (in bold type) are shown. The numbers above and below branches indicate bootstrap support percentages, based on 1000 replicates. (This figure is available in colour at JXB online.)
