FIG. 3.

Cluster analysis based on UPGMA of the temporal fecal cDNA-AFLP profiles of subject 1. DNA, total RNA, and enriched mRNA were used as starting material. On the left, similarity coefficients based on Pearson correlation are indicated, whereas the gray bars at the root of each cluster indicate the cophenetic correlation coefficients. Four different primer combinations are displayed: TR14/B03, Taq+AT/Bfa+G; TR14/B04, Taq+AT/Bfa+T; TR18/M17, Taq+CT/Mse+CG; TR14/M24, Taq+AT/Mse+TC, respectively. The different time points are indicated by t₀ and t₃. The gray shading in the distance tree indicates the variation introduced by DNA or mRNA profiling, respectively.
