Fig. 6. Increased JA production facilitates kor1 response to root hydrotropism.

Fig. 6

(A) Primary root elongation of indicated genotypes between 4 and 9 days after germination. Bars represent the means of 40 to 50 plants. Data were used to determine the root growth rate in millimeter per day by linear regression. (B and C) Root hydrotropic response of (B) WT and aos and (C) kor1-4 and kor1-4 aos seedlings. Representative images and circular histograms summarizing root curvatures of indicated genotypes 24 hours after transfer to split-agar Murashige and Skoog (MS) plates under mock (MS/MS) or hydrotropism-inducing (MS/400 mM mannitol) conditions. Bars indicate the percentage of seedlings exhibiting a root bending angle assigned to one of the 1820° sectors on the circular diagram [individual measurements are available in fig. S7 (D and E)], n = 42. Letters indicate statistically significant differences as determined by two-way ANOVA followed by Tukey’s HSD test (P < 0.05). Scale bars, 5 mm.
