Effects of SlETR7 mutants on responses to ethylene in etiolated seedlings. a, b Changes in seedling root length of WT, KO-L1, KO-L2, OE-L1 and OE-L2 lines as a function of ethylene concentration. Treatments were conducted at 25 °C in the dark for 6 days. Data represent the mean ± SD, n ≥ 5. Tukey’s HSD tests were performed (P < 0.05) to compare tomato lines at each ethylene concentration, and significant differences are highlighted by different letters. c, d Hook angle changes as a function of time after a 1 ppm ethylene treatment. Four-day old seedlings of each line were treated with 1 ppm ethylene. Data represent the mean ± SD, n ≥ 5, relative to time “0” for each line, value that set at “1”. Dunn’s tests were performed for multiple comparison with P < 0.05 between tomato lines at each time, and significant differences are highlighted by different letters
