Distributions of secondary cell wall pits in ropgef and ropgap mutants. Distribution of secondary cell wall pits in WT and ropgef4-1 ropgef7-1 plants (A–D), ropgap3-1 ropgap4-2 plants (E–H), or GAP3ox plants (I–M). (A,B,E,F,I and J) Histograms showing distances between secondary cell wall pits in WT (A,E and I) and mutant plants (B,F and J). n = 108 (A), 64 (B), 69 (E), 63 (F), 90 (I), and 110 (J) pits. (C,G and K) Degree of skewness of distributions of distances between secondary cell wall pits. White rectangles represent means; black bars represent medians; black dots represent outliers; n = 12 (C and K) and 10 (G) plants; ***P < 0.001, **P < 0.01, *P < 0.05; student’s t test (C and K); Wilcoxon rank sum test (G). (D,H and M) Omni-directional images of metaxylem vessel cells. Scale bars = 5 µm. (L) Distances between secondary cell wall pits in wild type and GAP3ox plants. Data are the mean ± SD (n = 12 plants). ***P < 0.001; student’s t test.
