Reference Genes for Accurate Transcript Normalization in Citrus Genotypes under Different Experimental Conditions (original) (raw)
Figure 2
Average expression stability values (M) calculated by geNorm.
M values of the remaining candidate citrus reference genes during stepwise exclusion of the least stable citrus reference gene in the different subsets. The ranking of the reference genes is in Table 2. A lower M value indicates more stable expression. (a) Total citrus samples examined, (b) Different citrus tissues or organs, (c) Fungal or oomycete stress, (d) Bacterial stress and (e) Viral stress.
