Freeze-fracture observations of the plasma membrane of the amoebae of the cellular slime mould Polysphondylium pallidum during encystment showed a rapid increase in the density of intramembrane particles, especially in the EF face. This density remained high during the formation of the microcyst wall and then fell abruptly to the much lower values typical of the resting microcyst. During germination there was a corresponding increase in intramembrane particle density which continued to a level typical of vegetative amoebae. These results are discussed in the light of recent biochemical studies of microcyst formation, cellulose biosynthesis and microcyst germination.
对细胞黏菌苍白聚孢霉变形虫在包囊化过程中质膜的冷冻蚀刻观察表明，膜内颗粒密度迅速增加，尤其是在EF面。在微囊壁形成过程中，这种密度保持较高，然后突然降至静止微囊典型的低得多的值。在萌发过程中，膜内颗粒密度相应增加，并持续到营养变形虫典型的水平。根据最近关于微囊形成、纤维素生物合成和微囊萌发的生化研究对这些结果进行了讨论。
