Morphological and Cellular Phenotypes of Arabidopsis Vegetative Actin Single Mutants.

(A) to (E) Mophological phenotypes of root hair or root growth defects.

(A) Four-day-old wild-type and mutant (act2-1, act8-2, and act7-4) seedlings.

(B) to (E) Portions of primary roots depicting defects in root hair development. Bars = 200 μm.

(F) to (T) Cellular phenotypes of F-actin cytoskeletal organization. Confocal microscopy maximum projection images of developing root hairs of wild-type ([F] to [L]) and act2-1 ([M] to [Q]), act8-2 ([R] and [S]), and act7-4 (T) mutants. All plants express the GFP-fABD2 fusion protein construct. Bars = 20 μm.
