7dSh (1) reduces the growth of A. thaliana seedlings. a Morphological appearance of autotrophically grown Arabidopsis thaliana seedlings 7 days after induction of germination. Seedlings were grown in constant light on agar plates without an antimetabolite (control) or in the presence of 7dSh or glyphosate. Plates were mounted vertically and illuminated from above. White arrows mark the root and shoot apical meristem. Scale bar (5 mm) applies to all images. b Measurement of the distance between root and shoot apical meristem. Significant differences between seedling sizes were analyzed in an unpaired t-test (*p-value < 0.05; ** p-value < 0.01; *** p-value < 0.001; n.s., not significant). Box-and-whisker plots represent the values of at least 16 seedlings. c Effect of 7dSh and glyphosate (each 260 µM) on the growth of A. thaliana on soil after 18 days in a day/night cycle. Statistical analysis was performed by using a one-way ANOVA. Tukey’s multiple comparison test was used as the post-hoc test. Means that were significantly different (p-value < 0.05) are marked with different capital letters in the diagram. Box-and-whisker plots represent the values of at least 58 A. thaliana seedlings. For b, c: Error bars indicate range, box bounds indicate second and third quartiles, center lines indicate median. Source data are provided as a Source Data file
