Abstract: The distribution and variation of microfilaments (MFs) in the maize root cap detached cells were examined under confocal laser scanning microscopy (CLSM) by using TRITC-phalloidin (TRITC-Ph) as fluorescent probe. The results showed that the microfilaments network was distributed on the root cells. The microfilaments were interweaved each other and connected with fluorescent particles. The microfilaments networks were dense and some radiative MFs bundles distributed around the nucleus and organelles. This suggested that the microfilaments were correlative with their function. Both CB and HMC toxin, a host-specific toxin from Bipolaris (Helminthosporium) maydis race C, could destroy the MFs distribution and had obvious quantity-effects relations.

Key words: Root cap cells, Microfilaments (MFs), Bipolaris (Helminthosporium) maydis race C toxin (HMC), Confocal laser scanning microscope (CLSM)
