Figure 6.

Drought-accelerated flowering is partially dependent on the SlOST1–SlVOZ1 module. A and B, Representative phenotypes and electrolyte leakage of WT, slost1 and slvoz1 mutants (MT background) under control (H₂O) and 200-mM mannitol treatment conditions. Data are means ± sd of three biological replicates. Different letters indicate significant differences by two-way ANOVA (Analysis of Variance) (Duncan’s multiple range test, P < 0.05). C, WLR of WT, slost1 and slvoz1 mutants. Data are means ± sd of three biological replicates. D, False-colored infrared-thermal images of the WT, slvoz1 and slost1 mutant plants. E, Flowering phenotype of WT, slost1 and slvoz1 mutants (MT background) under normal and drought treatment conditions. Scale bars, 5 cm. F, Flowering time of WT, slost1 and slvoz1 mutants under normal and drought treatment conditions. Data represent mean ± sd (n = 6), and experiments were repeated 3 times independently with similar results. G, Relative SFT transcript levels in 18-day-old WT, slost1, slvoz1 seedlings under control and mannitol treatment conditions. Tomato Actin 7 was used as a reference control. Data represent mean ± sd from three technical replicates. Different letters represent significant differences, as determined using two-way ANOVA with Tukey’s post hoc test (P < 0.05).
