Figure 2

Neighbour-joining tree showing the relationships among the coding sequences of the Antirrhinum and Misopates S-RNases and those of the three published Antirrhinum S-allele cDNAs. The names of the different sequence types are as in Table 1, and the lengths of the putative introns are shown in parentheses. The numbers by the nodes of the tree are bootstrap values greater than 68%.
