Fig. 4.

Transverse and longitudinal stalk sections of B73 (A, C) and bv1-1302 mutant (B, D) internode 8. Cells of bv1-1302 parenchyma cells had an average height of 66.2 vs 89.5 μm for B73 cells (standard error 3.9 and 3.4 μm, respectively, n=30). Both parenchyma and vascular cells are visible in the four panels. Cells of bv1-1302 were wider than B73 cells (178.9 vs 125.9 μm, respectively; standard error 5.6 and 4.9, respectively, n=30). Samples were taken 91 d after planting after the tassel had fully emerged from the whorl. Bars, 400 μm.
