Figure 4From: Identification and validation of quantitative real-time reverse transcription PCR reference genes for gene expression analysis in teak (Tectona grandis L.f.)Gene expression stability of the candidate reference genes calculated by different statistical methods. Ranking of each candidate reference gene (rp60s, Act, Cac, Ef-1α, GAPDH, His3, Sand, B-Tub, Ubq) calculated by NormFinder, BestKeeper, geNorm and Delta Ct methods, for all tested cDNA samples (leaf, flower, seedling, root, stem secondary xylem, branch secondary xylem).Back to article page
