Figure 2.

Confocal laser scanning analysis of lateral roots in WT, slr1, and slr2. Propidium iodide-stained lateral roots from the middle part of the primary root of 8-d-old maize seedlings were analyzed and cortical cells from the basal part of the lateral roots were focused. Optical sections inside the lateral roots were scrutinized at various levels, and images obtained from the basal part showing striking differences are presented in WT (A), slr1 (B), and slr2 (C). Bar indicates 200 μm. Arrows and asterisks indicate root hairs on lateral root and primary root, respectively.
