Ranking of <i>Araucaria angustifolia</i> candidate reference genes based on GeNorm analysis.

a Stability coefficient is the mean of the variation of two internal control genes between an individual and all other tested genes. The most stable gene has the lowest M value (cut-off < 1.5). b Pairwise variation values Vn/n+1 < 0.15 mean that use of the two most stable genes is sufficient to normalize the expression of a test gene in the corresponding set of samples. n: number of genes.
