Pharmacological modulators of MT organization affect compatible pollination. Average number of adhered pollen grains (A) and germinated pollen tubes (B) on W1 stigmas treated with either taxol or oryzalin, followed by compatible or self-incompatible pollinations with Westar and W1 pollen respectively. n = 5; error bars are ± standard error. The representative DIC and aniline blue fluorescence images (to visualize pollen tubes) of stigmas from the compatible treatments are shown in C. HAP, Hours after pollination.
