Effect of camphor and menthol on the cytoskeleton in stomata guard cells. Effect of camphor (10 mg/l) and menthol (5 mg/l) on the cytoskeleton in stomata of Arabidopsis thaliana cotyledons. Actin cytoskeleton visualized with the 35S::GFP:FABD2 construct as in vivo marker for filamentous actin in control conditions (A) and after treatment with monoterpenoids for 48 h (B). Arrows point to the patches of bundled F-actin. Microtubular cytoskeleton visualized with the 35S::GFP:MBD construct as in vivo marker for microtubules in control conditions (C) and after treatment with monoterpenoids for 48 h (D). Note pronounced bundling of microtubules (arrowheads) and appearance of short disrupted microtubular bundles (arrows). Bar: 10 µm.
