原生动物包囊的研究进展

对几乎所有的原生动物细胞而言,在一定条件下形成包囊是一种普遍的现象,它可在一定程度上降低了生存代价,是一种从某种意义上讲比某些高等生物更具优越性的生存策略。以国内外文献报道为依据,综述了原生动物包囊,特别是休眠包囊的研究进展情况,主要集中在包囊的形态、结构、组成、生命活动特征、包囊形成的分子作用机理和意义,以及包囊形成与解脱过程中细胞行为上的研究等方面。

Advances in the Studies on Cysts of Protozoans

It is common for almost all protozoans to encystment under certain conditions.Compared with some high life-forms,the phenomena of encystment in protozoa is a more ascendant survival strategy in certain meaning since it can reduce the cost of adaptation.This paper reviewed the research progresses about the cysts,especially the resting cysts of protozoans,mainly focused on the characteristics of morphologies,structures,constituents,and living activities,as well as molecular mechanism and significance of encystment for the protozoans,also,cell behavior during encystment and excystment was involved based on the references reported.
