Figure 7From: Identification and validation of quantitative real-time reverse transcription PCR reference genes for gene expression analysis in teak (Tectona grandis L.f.)Venn diagrams. (A) the most stable reference genes present in the first four positions and (B) the least stable genes present in the last five positions identified by the NormFinder, BestKeeper, geNorm and Delta Ct methods. Diagrams were performed with the Smartdraw® program.Back to article page
