Figure 5From: Identification and validation of quantitative real-time reverse transcription PCR reference genes for gene expression analysis in teak (Tectona grandis L.f.)Gene expression differences among the candidate reference genes analyzed by NormFinder. Black circles represent the log-transformed gene expression levels. Vertical bars give a confidence interval for the inter-tissue variation. Top and bottom lines from the graphic represent the maximum standard deviation of the candidate reference genes, with the difference log expression levels between 0.2 and -0.2.Back to article page
