摘　　要：High temperature(HT)has major effects on the growth and production of vegetable crops,including eggplant(Solanum melongena L.).Eggplant seedlings,flower organs,and fruits are affected by high temperature stress(HTS).Nonetheless,key HT response factors are rare in eggplant.In this study,we found that SmEGY3 was localized in chloroplasts and nuclei,and the expression was induced by HT.We confirmed that SmEGY3 played a positive role in regulating heat tolerance of plants by virus-induced gene silencing(VIGS)and overexpression assays.Compared to the control plants,the SmEGY3-silenced plants showed significantly decrease in the H_(2)O_(2) content and H_(2)O_(2)-mediated retrograde signalling genes expression while the SmEGY3-overexpressing plants displayed significantly increase.
