Figure 1

The expression levels of the reference candidates over all treatments. The boxplot graphs show the measured quantification cycles (Cq) for all candidate genes comprising all genotypes (93/1-119, 94/1-30 and 94/1-97), all tissues (leaves, roots and immature flower buds) and all treatments (heat shock, wounding, black spot inoculation for 2 h and 3 d) of genotype 93/1-119. The boxes represent 25 and 75 quartiles, the whisker caps indicate 10 and 90 percentiles, and the medians are indicated by the line. The number of included Cqs is indicated by n.
