Table 5 Correlation of the candidate reference genes rank according to the evaluation based on four statistical algorithms for three comparison groups (leaves inoculated with low dose of Pseudomonas syringae pv. actinidiae inoculum (LDI), leaves inoculated with high dose of P. s. pv. actinidiae inoculum (HDI) and all samples combined together (Total)).

From: Reference gene selection for normalization of RT-qPCR gene expression data from Actinidia deliciosa leaves infected with Pseudomonas syringae pv. actinidiae
