Fig. 3. Effects of low concentrations of oryzalin (0.1 or 0.3 µM) or paclitaxel (1 µM). Treatments were initiated 16-17 hours AF. (A) Centrosomal alignment angles were measured on zygotes prior to treatment and during mitosis. (B) Distances between centrosomes at telophase. Data points in A and bars in B are the means±s.d. of two or three experiments. (C-F) Microtubule arrays in 0.3 µM oryzalin (C), 0.1 uM oryzalin (D), or 1 uM paclitaxel (E,F).
