The effect of GAMYB-like1-silencing on tomato seedlings under chilling stress. a Relative expression levels of GAMYB-like1 in WT, Ve and VGAMYB-like1 plants. b Phenotypes of WT, Ve and VGAMYB-like1 lines under control (25 °C) conditions. c Phenotypes of WT, Ve and VGAMYB-like1 lines under chilling (4 °C) conditions for 4 h; d Phenotypes of WT, Ve and VGAMYB-like1 lines under chilling (4 °C) conditions for 8 h. e and f Effects of chilling stress on REL (e) and MDA (f) in WT, Ve and VGAMYB-like1 lines. g Relative expression levels of key genes involved in chilling and ROS signaling. The data are means of three biological repeats ± the standard deviation (SD). Asterisks indicate significant differences between gene-silencing lines and WT. *, P < 0.05; **, P < 0.01, Student’s test
