The effect of overexpression of sha-miR319d on plant growth under control and temperature-stress conditions. a Phenotypes of WT and transgenic lines (T2 generations) under control (25 °C) conditions. b Phenotypes of WT and transgenic lines (T2 generations) under chilling (4 °C) conditions for 5 d. c Phenotypes of WT and transgenic lines (T2 generations) under heat (40 °C) conditions for 5 d. d, e Effects of chilling stress on REL (D) and the MDA content (f) in WT and transgenic lines (T2 generations). f, g Effects of heat stress on REL (F) and MDA (g). The data in (d-g) are the means 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
