Figure 3From: Sequence analysis of percent G+C fraction libraries of human faecal bacterial DNA reveals a high number of ActinobacteriaPhylogenetic tree of actinobacterial OTUs in the fraction libraries and in the unfractioned library. The amount of sequences in the representative OTUs are denoted after the letter F (fractioned sequence libraries) and U (unfractioned library). Bootstrap values are percentages of 100 resamplings and the scale bar represents 0.05 substitutions per nucleotide position.Back to article page
