Cortical Microtubule Arrangement in Different Root Hair Zones of L. japonicus Plants Exposed to Purified M. loti Nod Factors.
(A) Average microtubule length (n = 1168 microtubules from 146 root hairs).
(B) Microtubule (MT) length in Zone II root hairs as a function of distance from root hair tip (n = 450 microtubules from 75 root hairs).
(C) Average microtubule angular orientation (n = 1185 microtubules from 145 root hairs).
(D) Microtubule (MT) angular orientation in Zone II root hairs as a function of distance from root hair tip (n = 954 microtubules from 106 root hairs).
Double asterisks indicate a statistically significant difference at P < 0.001, and single asterisks indicate a statistically significant difference at P < 0.05, according to ANOVA. Values were compared with those for controls given in Figures 1C and 3A.
