Figure 1
Expression levels of eight candidate reference genes. The values are given as real-time PCR quantification cycle (Cq) values for individual reference genes in a total of 12 samples (in duplicate) from the individual timepoints in the 2009 (96, 109, 116 and 136 DAF) crop season from cultivars Barnea, Frantoio and Picual. The boxes represent the 25th and 75th percentiles and the line within the boxes represents the median. The whiskers indicate the range of Cq values of the data of the 24 samples per reference gene.
