Figure 6

Cortical actin filament orientation is affected in rpi1 mutant. (A) Cortical actin filaments are mainly longitudinal along the direction of elongation in 4-day-old control seedling root cells (arrowheads). Each figure is a maximum projection of five slices z-stack. (B) Cortical actin filaments are transversely oriented in root cells of 4-day-old rpi1 seedling (arrowheads). Each figure is a maximum projection of five slices z-stack. (C, D) Cortical actin filaments are randomly oriented in the meristem zone in (C) wild type and (D) rpi1. Arrows indicate phragmoplast-enriched actin filaments. Bars = 50 μm in (A, B) and 20 μm in (C, D).
