Abstract
The nuclear matrix of diplomonad Giardia lambBa was detected for the first time with DGD embedment-sectioning-embedment free electron microscopy after a series of specific extractions. The result showed that archaezoa Giardia lamblia already possessed nuclear matrix within its two nuclei. The finest fibrils of the nuclear matrix of Giardia lamblia were measured to be about 11 to 13 nm in thickness. However, the nuclear lamina and nucleolus have never been observed. These results seem to suggest that nuclear matrix is an indispensable intranuclear structurM component even in the primitive nucleus.
