Root hair patterning in A. alpina . A) Wild type A. alpina root; A(i), Higher magnification of the lower root hair differentiation zone; A(ii), Higher magnification of upper root hair differentiation zone. Root hair file (H), Non-root hair file (N) and non-root hair file with root hair stretches (D-file) is indicated by arrows. B) Aattg1-1 root; B(i), Higher magnification of the lower root hair differentiation zone; B(ii), Higher magnification of the upper root hair differentiation zone. C) Wild type A. alpina root cross section depicting one root hair at the H-position over the cleft of two underlying cortex cells and a neighboring root hair in an N-position. D) Percentage of root hairs in root hair files (H) and non-root hair files (N). E) Relative number of cells in H and N files. A ratio of about two reflects that the non-hair cells are twice as long as the H-cells. F) Number of cells in continuous stretches of root hair cells in the N files. Scale bar: 100 μm in A,B; Scale bar: 40 μm in C. ***: P < 0.001, **: P < 0.01.
