摘要

Abstract

The ultrastructure of extrusomes of the hypotrichous ciliate Pseudourostyla nova was observed in scanning and transmission electron microscopy and enzyme-cytochemistry. The results show that the distribution

morphological characteristics

morphogenesis process

and extrusive process of the extrusomes in P. nova are different from the trichocysts in Paramecium

suggesting that the extrusomes of P. nova can respond to environmental stimuli

play an important role in the defense of this species

and cannot be regarded as “trichocysts”. The results also suggest that the extrusomes might be originated from the Golgi apparatus and mature in the cytoplasm; after the extrusion of mature extrusomes

the residual substance might be reabsorbed and reused by the ciliate cell via food vacuoles

and take part in material recycling of the cell.
