Phylogenetic tree derived from a CLUSTAL analysis of the full ORF sequences of Arabidopsis coiled-coil proteins. The seven AtFPP sequences (boxed) were aligned together with 35 additional Arabidopsis coiled-coil proteins that had been annotated as "myosin-like". The length of each pair of branches measures the distance between sequences. Units indicate the number of computed residue substitution events. Dotted lines have no unit length and were included for alignment purposes. ORFs were identified by their TAIR gene names, accessible through http://www.arabidopsis.org.
