The 3 most stable genes were EIF4A, GAPDH and TUB for the different developmental stages; EIF4A, GAPDH and EF for the different body parts; EF, RPL13A and GAPDH for the low-temperature challenge; G6PDH, 18S and EIF4A for fungal infection; and EF, GAPDH and TUB for the different diets treatment (Fig 1). This evidence concerns the gene TUB and fungal infectious disease.
