Influence of changes in shoot vigour on the size of root epidermal cells. (A) Single plane confocal microscopy image of root epidermal cells showing trichoblasts (green outline) and atrichoblasts (magenta outline). Trichoblasts were identified by changing the focus to identify those with root hairs. (B) Surface areas of the trichoblasts and atrichoblasts of C0 lines. The area measured was ‘surface 2’ of Supplementary Fig. S1 (n=64). (C) Cell body volumes of trichoblasts and atrichoblasts (excluding the root hair volume) for each cycle of the recurrent selection for shoot vigour (n=75 per cell type and cycle). (D) Total cell volumes of trichoblasts including root hair volume (n=75 per cell type and cycle). The error bars represent SEs, and different letters identify significant differences between means at P=0.05.
