Figure 2

Consensus unrooted distance tree of 5S rDNA spacers from Nicotiana tabacum (NTA131161–67), N. tomentosiformis (NTO131175–79), N. otophora (NOT131172–74), and N. sylvestris (NSY131168–71). The names of spacers are as published in GenBank. The tree was generated from 100 bootstrapped multiple analyses (see methods). The numbers at the forks indicate the number of times the branch point occurred among the trees (out of 100). The tree is divided into two main groups corresponding to the S-genome and T-genome 5S rDNA families. The T-genome family is divided into two subgroups that cluster sequences according to spacer length.
