Figure 3From: Repeated reunions and splits feature the highly dynamic evolution of 5S and 35S ribosomal RNA genes (rDNA) in the Asteraceae familyQuantification of the linked rRNA genes copy number by real time PCR. The Pr1-5SLf primer set (Figure 1A) was used to amplify inversely positioned 26S-5S genes. The graph shows mean values obtained from three independent experiments. Example of the amplification plot for Artemisia and Elachanthemum is shown in Additional file 2.Back to article page
