From: Fine organization of genomic regions tagged to the 5S rDNA locus of the bread wheat 5B chromosome
Neighbor-joining phylogenetic tree of representative clusters of 5S rDNA, sequenced from pool 52 and pool 89. The phylogenetic tree was constructed using a CLUSTALW multiple alignment for the 5S rDNA spacer nucleotide sequences (neighbor-joining method, pairwise deletion option, 500 bootstrap replicates). Bootstrap support over 50% is shown for the corresponding branches. The number of spacer sequences united in the cluster is indicated in brackets. The ShortA1, ShortG1, ShortA2 and LongS1 unit types used are also shown [10]. The branches are designated as ShortA1, ShortA2 and LongS1 based on the presence of the relevant 5S rDNA type
