Fig. 4: Effect of ethylene and 1-MCP treatment on WT and SlGRAS4-OE fruit.
From: SlGRAS4 accelerates fruit ripening by regulating ethylene biosynthesis genes and SlMADS1 in tomato

a Phenotypes of WT and SlGRAS4 OE #18 fruit after treatment with ethylene for 48 and 72 h, respectively. The fruit were picked at the mature green stage for ethylene treatment. b Phenotypes of WT and SlGRAS4 OE #18 fruit after treatment with 1-MCP for 72 h. The fruit were picked at the breaker stage for 1-MCP treatment. c The expression levels of SlACS2, SlACS4, SlACO1, and SlACO3 in WT and SlGRAS4-OE fruit after treatment with ethylene for 72 h. d The expression levels of SlACS2, SlACS4, SlACO1, and SlACO3 in WT and SlGRAS4-OE fruit after treatment with 1-MCP for 72 h. In (c) and (d), the data represent the mean values of three independent experiments, and error bars show the ±standard error values. * and ** refer to significant differences between WT and transgenic lines with P < 0.05 and P < 0.01, respectively (two-tailed Student’s t-test)
