Figure 6From: Identification and validation of quantitative real-time reverse transcription PCR reference genes for gene expression analysis in teak (Tectona grandis L.f.)Pairwise variations (V) calculated by geNorm to determine the optimal number of reference genes. The average pairwise variations Vn/n+1 was analyzed between the normalization factors NFn and NFn+1 to indicate the optimal number of reference genes required for qRT-PCR data normalization in all the samples, lignified tissues (root, stem secondary xylem, branch secondary xylem), non-lignified tissues (leaf, flower, seedling) and in all samples minus stem secondary xylem.Back to article page
