Mutant rip1–6 lines exhibit microfilament defects. a, b Roots of 5 days old wild type (WT) and rip1–6 plants. Bar = 2 mm. c, d WT and rip1–6 root tip microfilaments stained with phalloidin. Bar = 50 µm. e, f Enlargements of boxed areas in (c) and (d), respectively. Bar = 10 µm. g Actin filament abundance, or percentage of occupancy, in WT and rip1–6 root tips. n = 40, **P < 0.005 (Student’s t-test). h Actin filament bundling, or skewness, in WT and rip1–6 root tips. n = 40
