Phenotypic Analysis of Arabidopsis Vegetative Actin Double Mutants.

(A) and (B) Four-day-old wild-type and actin double mutant (act2-1 act7-4 [2/7], act8-2 act7-4 [8/7], act2-1 act 8-2 [2/8]) seedlings.

(C) Shoots of 20-d-old double mutant seedlings. For wild-type control, a single leaf from a seedling of the same age is shown for comparison.

(D) Scanned images of ∼18-d-old wild-type (Wassilewskija) and double mutant seedlings showing differential defects in root development.

(E) Five-week-old plants.

(F) to (H) Portions of the primary roots of double mutants depicting different defects in root hair development.
