Fig. 5From: Overexpression of Solanum habrochaites microRNA319d (sha-miR319d) confers chilling and heat stress tolerance in tomato (S. lycopersicum)The effect of overexpression of sha-miR319d on the activities of antioxidant enzymes. a SOD activities of WT and transgenic plants under control, chilling stress (4 °C) and heat stress (40 °C) conditions. b CAT activities of WT and transgenic plants under control, chilling stress (4 °C) and heat stress (40 °C) conditions. c APX activities of WT and transgenic plants under control, chilling stress (4 °C) and heat stress (40 °C) conditions. T2 generations of transgenic plants as well as WT were used. Each value is the mean of three biological repeats ± the standard deviation (SD). Asterisks indicate significant differences between transgenic lines and WT. *, P < 0.05; **, P < 0.01, Student’s t test.Back to article page
