Abstract To screen for suitable internal reference genes in eggplant under diff erenttissues and adversity stresses，UBC，EF-1a，18S，Actin，GAPDH，β-TUB，L33 and EF2，eight candidate internal reference genes were selected in this study under eight experimental conditions，including flood stress，drought stress，cold stress，heat stress，Verticillium dahliae infestation，salt stress，salicylic acid treatment and different tissue sites．The stability of candidate internal reference genes was analyzed using geNorm，NormFinder，ΔCT，Bestkeeper and RefFinder under eight test conditions．The results showed that Actin was the most stable internal gene among all samples，cold stress，heat stress，Verticillium dahliae infestation and salt stress，β-TUB was the most stable gene expressed under flooding stress，EF2 was the most stable under drought stress，EF-1a was the most stable gene expressed under salicylic acid treatment，and 18S was the most stable among different tissue sites．UBC，L33 and GAPDH were not stably expressed under all treatments．This study provides stable internal reference genes for the study of gene specific expression in different tissues of eggplants and under adversity stress．
