Figure 4From: Reference gene selection for quantitative reverse transcription-polymerase chain reaction normalization during in vitro adventitious rooting in Eucalyptus globulus LabillDetermination of the optimal reference gene number as calculated by geNorm for accurate normalization during Eucalyptus globulus in vitro adventitious rooting. geNorm pairwise variation values (V values) are calculated by an algorithm which measures pairwise variation (Vn/n + 1) between two sequential normalization factors NFn and NFn + 1, where n is the number of genes involved in the normalization factor.Back to article page
