Soil-holding capacity of the seedling root. (a) Representative images showing soil held by the seedling root of control (Cont) and transgenic lines overexpressing RHS10 (RHS10ox), axr2-1 (axr2-1ox), RSL4 (RSL4ox), and IAA2mImI (IAA2mImIIox) after pulling out seedlings from soil. Bar is 5 mm for all. (b) Soil amount retained by the root after pulling out seedling. Data represent mean ± s.e.m. (n = 11–26 from each line). Statistically significant differences are denoted with different letters (one-way ANOVA with Tukey’s unequal N-HSD post hoc test, P < 0.05) (c) Magnified images of soil particles held by the root. Bar is 0.5 mm for all.
