From: Reference gene selection for gene expression studies using RT-qPCR in virus-infected planthoppers
Stability analysis of the candidate reference genes in Delphacodes kuscheli adult planthoppers. The housekeeping genes were ranked according to their expression stability by (A) geNorm, (B) Normfinder and (C) BestKeeper statistical tools. In the three plots, genes were ordered from least (left) to most (right) stable. Pair-wise correlation analysis between the candidate reference genes and the calculated BestKeeper index is also shown (C, bottom) and the higher correlated genes were highlighted in grey.
