Figure 2From: CandidatusLiberibacter americanus induces significant reprogramming of the transcriptome of the susceptible citrus genotypeAverage expression stability values (M) and Pairwise variation (V) of the ten citrus reference genes calculated by geNorm. A) A lower M value indicates more stable expression. B) Pairwise variation (V) to determine the optimal number of reference genes suggested by geNorm to a reliable normalization.Back to article page
