Figure S1 – Information about quality of RT-qPCR results.Boxplot of quantification cycle (Cq) measured on 34
individual heads for 3 genes: for , rpl32 , gapdh .
The rpl32 and gapdh used as reference gene to normalisedfor expression exhibited less variation among samples than thefor gene (F-test; p-val<0.05) but do not differ between
them. Cq values were lower in reference genes than infor gene, indicating that rpl32 and gapdh have a
higher expression compared to for gene.
