Effects of Paclitaxel Treatment on the Actin Cytoskeleton and of Latrunculin B on the Microtubular Cytoskeleton in Trichomes.

(A) A radially swollen wild-type trichome obtained after treatment with paclitaxel exhibits intact and elongated F-actin strands.

(B) A trichome of stichel with a subapical bulge, obtained after prolonged paclitaxel treatment, shows elongated F-actin strands following the cell periphery.

(C) A stichel trichome with a swollen apex displayed thick continuous actin bundles.

(D) A wild-type trichome became distorted, with unextended branches. The transverse cortical microtubule array appears undisturbed.

(E) Stichel trichomes treated with latrunculin B are short, stubby, and wavy. Note that the cortical microtubule array appears undisturbed.
