Microscopic observation of the developing panicles in WT and pmm1–1. Scanning electron microscopy (SEM) analysis of young panicle development between WT (a-d) and pmm1–1 (e-h) at the vegetative stage (a, e), the primary branch primordial formation stage (b, f), the second primordial formation stage (c, g), the spikelet primordial formation stage (d, h). Longitudinal section analysis of young panicle development in WT (i, j) and pmm1–1 (k, l) at the primary branch primordial formation stage (i, k) and the second primordial formation stage (j, l).
