According to the coefficient of determination of each gene, the 3 most stable genes were EIF4A, GAPDH and EF for the different developmental stages; EF, EIF4A and GAPDH for the different body parts; EIF4A, RPL13A and EF for the low-temperature challenge; GAPDH, EF and TUB for fungal infection; and ACT, TUB and EF for the different diets treatment (Table 2). Here, RPL13A is linked to fungal infectious disease.
