Figure 2From: Tracking the best reference genes for RT-qPCR data normalization in filamentous fungi geNorm–based ranking of the putative reference genes. (A) Genes were ranked from the least stable (on the left) to the most stable (on the right) according to their M value (Y axis). This classification was independently performed by using different sets of conditions: the ‘All conditions’ included the whole set of culture conditions studied by RT-qPCR in this work; the ‘C sources’ subset gathered the 18 samples obtained from growth on different sugars; the ‘Stress’ subset corresponded to 6 samples harvested during stress exposition; the ‘Germination’ subset included the 6 germination time points. For each set of conditions, the result of the classification was given below the X-axis (arbitrary colours attributed to each gene for the sake of clarity). (B) Result of the pairwise variation analysis between NFn and NFn+1 to determine the optimal number of genes for reliable normalization. Values below the 0.15 threshold mean that n genes might be sufficient.Back to article page
