Relative gene expression of SOD1, APX2 and CAT genes (Top) and protein blots and quantitative bar graphs (Bottom) of SOD1, APX2 and CAT proteins. Both analyses were performed in Carrizo and Cleopatra plants self-grafted or grafted into each other after drought and heat stress combination. Data are mean values ± standard errors (n = 3). Asterisks denote Student’s t test significant at p < 0.05 between control and stressed plants within each grafting group
